TwilioLookup API

TwilioLookup API

Twilio Lookup is a real-time phone number intelligence API that provides instant validation, carrier identification, line type detection, and fraud signals for any phone number globally. Built on Twilio's extensive carrier network relationships, Lookup enables developers to query phone number metadata before sending SMS messages, onboarding users, or processing transactions โ€” helping reduce messaging failures, detect fraud, and route communications optimally. For Nigerian developers, Twilio Lookup is particularly useful for identifying which of the four main Nigerian carriers (MTN, Airtel, Glo, 9mobile) a given number belongs to, detecting VoIP numbers commonly used in fraud, and identifying SIM Swap events that signal potential account takeovers. ## What the API Does Twilio Lookup v2 provides phone intelligence through a modular add-on system. The base request provides free E.164 format validation and number standardization. Paid add-ons provide richer intelligence: **Basic Lookup (Free)**: Validates phone number format, returns E.164 and national format, and confirms the number exists in Twilio's records. No carrier data. **Carrier Lookup ($0.005/lookup)**: Returns the carrier name, mobile country code, mobile network code, and line type (mobile/landline/VoIP) for the phone number. For Nigerian numbers, this identifies which carrier (MTN Nigeria, Airtel Nigeria, Globacom, 9mobile) the number is on. **Line Type Intelligence (paid add-on)**: Classifies numbers into: mobile, landline, fixed VoIP, non-fixed VoIP, toll-free, or unknown. This classification is available for all countries worldwide. **SIM Swap**: Detects recent SIM card changes on a mobile number โ€” a critical fraud signal indicating potential account hijacking. Returned as hours since last SIM change. **Caller Name (CNAM)**: Returns the registered name for the phone number (primarily US numbers, limited international availability). ## How Developers Use It Twilio Lookup is a simple REST API. A single GET request to `https://lookups.twilio.com/v2/PhoneNumbers/{PhoneNumber}` returns the requested intelligence. Add query parameters to enable specific packages: ``` GET /v2/PhoneNumbers/+2348012345678?Fields=line_type_intelligence,sim_swap ``` Authentication uses your Twilio Account SID and Auth Token as HTTP Basic Auth credentials. ## Pricing & Fees - **Basic validation**: Free โ€” no charge for E.164 format lookup. - **Carrier lookup**: $0.005 per lookup (half a cent per number checked). - **Line Type Intelligence**: Paid add-on โ€” pricing available at twilio.com/en-us/user-authentication-identity/pricing/lookup. - **SIM Swap**: Per-query fee varies by country. - **Caller Name**: Per-query fee for supported regions. ## Authentication HTTP Basic Authentication using your Twilio Account SID (username) and Auth Token (password). These are found in the Twilio Console. For production use, Twilio recommends creating scoped API Keys rather than using the master Auth Token directly. ## Rate Limits Standard Twilio account-level rate limits apply. These vary by account tier. Contact Twilio support or review the Console for your account's specific limits. ## Compliance & Regulations Twilio is ISO 27001 certified, SOC 2 Type II attested, and GDPR compliant. Twilio Lookup processes phone number metadata without storing user personal information beyond what is necessary for query processing. For Nigerian deployments, the carrier and line type data returned by Lookup can support CBN KYC requirements around phone number verification as part of customer due diligence. ## Challenges & Gotchas for Nigerian Developers 1. **VoIP detection for fraud**: Nigerian number fraud often uses VoIP numbers. Always check line_type_intelligence during registration and block non-fixed VoIP registrations. 2. **SIM Swap coverage**: SIM swap detection coverage varies by carrier. Confirm Nigerian carrier coverage (MTN, Airtel, Glo, 9mobile) is included before relying on this feature for fraud prevention. 3. **Carrier lookup cost vs. value**: At $0.005/lookup, checking every user registration costs $5 per 1,000 users. For high-volume apps, model this cost against the fraud prevention value. 4. **USD billing**: Twilio charges in USD. Use a USD virtual card or wire transfer. 5. **CNAM limited for Nigeria**: Caller name lookup has limited availability outside the US. Do not rely on CNAM for Nigerian number enrichment. ## Company Background Twilio Lookup is part of Twilio's User Authentication and Identity product suite, operated by Twilio Inc. (NYSE: TWLO), a publicly listed cloud communications company founded in 2008 in San Francisco. Twilio's global carrier network and data partnerships power the phone intelligence provided by Lookup. ## Frequently Asked Questions **Q: Is basic phone number validation really free?** A: Yes. E.164 format validation and number standardization via Twilio Lookup is completely free with no per-query charge. **Q: Which Nigerian carriers can Twilio Lookup identify?** A: MTN Nigeria, Airtel Nigeria, Globacom (Glo), and 9mobile (formerly Etisalat) are all identifiable through the carrier lookup feature. **Q: Can I detect SIM Swap for Nigerian users?** A: Yes, but availability depends on the specific carrier's data-sharing agreements with Twilio. Confirm Nigerian carrier SIM Swap coverage with Twilio support before deploying. **Q: Does Lookup integrate with Twilio Verify?** A: Yes. Twilio Verify uses Lookup internally for carrier validation. You can use Lookup independently as a pre-send check before triggering Verify OTPs.

MTN SMS API

MTN SMS API

The MTN Developer API platform is the official developer program of MTN Group, Africa's largest mobile telecommunications company. MTN Nigeria is the country's largest mobile network operator with over 70 million subscribers, representing approximately one-third of Nigeria's entire mobile subscriber base. Integrating directly with the MTN Developer API gives Nigerian businesses and developers access to telecommunications capabilities โ€” SMS, USSD, subscriber services โ€” through a direct carrier connection rather than through a third-party aggregator, which translates to higher delivery rates, lower latency, and direct support from the network operator. The MTN SMS API allows businesses to send SMS messages directly to MTN Nigeria subscribers. Because messages are routed through MTN's own infrastructure rather than a third-party SMS aggregator, delivery rates for MTN numbers are typically higher than through aggregator routing. The API supports both transactional SMS (OTP codes, account alerts, order confirmations) and promotional bulk SMS campaigns (marketing messages, event notifications). Delivery receipts confirm message delivery status in real time via webhooks. This is critical for Nigerian fintech applications where delivery of OTP codes is time-sensitive and delivery failure means transaction failure. The USSD API is one of MTN's most strategically important offerings for the Nigerian market. USSD (Unstructured Supplementary Service Data) is a real-time communication protocol that works on every mobile phone โ€” including the most basic feature phones โ€” without requiring internet connectivity. USSD sessions are interactive, menu-driven conversations initiated by the user dialing a short code (e.g., *123#). For Nigerian financial services, agriculture, healthcare, and government applications, USSD is the primary way to reach users who do not have smartphones or reliable internet access. Building a USSD service on MTN reaches tens of millions of Nigerians who are inaccessible via app or web-based interfaces. The subscriber lookup and verification capabilities allow businesses to query whether a given phone number is an active MTN Nigeria subscriber, check number portability status, and retrieve basic subscriber information (within regulatory permissions). For Nigerian platforms that need to verify phone number validity before sending messages or initiating calls, subscriber lookup helps reduce failed delivery costs and improve user experience. Authentication for the MTN Developer API uses OAuth 2.0 with client credentials flow, providing secure, token-based API access. API keys and secrets are managed through the MTN developer portal, and tokens are short-lived and automatically refreshed by the SDK or developer code. Access to the MTN Developer API typically requires registration on the developers.mtn.com portal with business verification. Consumer-grade features may be available immediately after registration, while enterprise features like USSD service provisioning and bulk SMS at scale require engagement with MTN Nigeria enterprise sales. Regulatory compliance requirements from the NCC (Nigerian Communications Commission) may apply to commercial API deployments. For Nigerian developers building fintech applications, the combination of MTN SMS for notifications and MTN USSD for service access represents a powerful stack for reaching the maximum possible Nigerian user base โ€” from the most digitally sophisticated smartphone users to rural feature phone users with no internet access. Banks, microfinance institutions, mobile money services, and insurance platforms in Nigeria have successfully deployed on MTN USSD to dramatically expand their addressable market. Pricing for MTN Developer API is commercial and based on usage volume. Nigerian naira pricing is available for domestic businesses. Enterprise accounts with committed usage volumes receive preferential per-message rates. Integration support is available through the MTN developer portal documentation, community forums, and enterprise support channels.

Easypost Shipping API

Easypost Shipping API

EasyPost is a US-headquartered shipping API platform that consolidates rate shopping, label printing, address verification, and tracking across 70+ major Western carriers (UPS, FedEx, USPS, DHL, Royal Mail, Canada Post, and more) into a single developer-friendly API. EasyPost does NOT support Nigerian domestic carriers and cannot be used for Nigeria-to-Nigeria shipping. Its primary relevance to Nigerian developers and businesses is for US and international operations โ€” specifically for businesses with US, UK, Canadian, or Australian shipping needs, Nigerian diaspora businesses, and Nigerian companies managing operations or shipments in Western markets. **What EasyPost Does** EasyPost provides four core shipping services: **1. Multi-carrier Rate Shopping** Submit package dimensions, weight, origin, and destination to receive rate quotes from all available carriers simultaneously. Compare USPS First Class vs UPS Ground vs FedEx Home Delivery for any US domestic shipment, or compare DHL Express vs FedEx International Priority for international routes. **2. Shipping Label Generation** After selecting a carrier and service level, create the shipment to receive a prepaid shipping label as a PDF or ZPL (thermal printer format) URL. Print and attach to the package. EasyPost's pre-negotiated rates with USPS, FedEx, and UPS are significantly lower than retail walk-in rates. **3. Address Verification** Validate US addresses before shipping to reduce failed deliveries. Returns the USPS-standardized address, residential/commercial flag, and deliverability status. **4. Shipment Tracking** Track any shipment across 70+ carriers using a unified tracking API. Returns normalized status events with timestamps and location data regardless of carrier. **Carrier Coverage (Western Focus)** US domestic: - USPS (all service classes: Priority Mail, First Class, Ground Advantage) - UPS (Ground, 2nd Day Air, Next Day Air, etc.) - FedEx (Home Delivery, Express, 2Day, Overnight, etc.) International from US: - DHL Express - FedEx International - UPS Worldwide - USPS Priority Mail International UK: - Royal Mail (various services) - DHL UK Canada: Canada Post, Purolator Australia: Australia Post, StarTrack **No Nigerian Carrier Support** EasyPost explicitly does not cover: - GIG Logistics - Red Star Express - Sendbox - Kwik Delivery - Any Nigerian domestic postal or courier service For Nigerian domestic shipping, use Sendbox, GIG Logistics API, or Konga Logistics instead. **How Developers Use EasyPost** Authentication uses HTTP Basic Auth with the API key as username: Rate shopping: ``` POST https://api.easypost.com/v2/shipments Authorization: Basic BASE64(YOUR_API_KEY:) { "shipment": { "from_address": { "street1": "123 Main St", "city": "New York", "state": "NY", "zip": "10001", "country": "US" }, "to_address": { "street1": "456 Oak Ave", "city": "Los Angeles", "state": "CA", "zip": "90001", "country": "US" }, "parcel": { "weight": 16, "length": 8, "width": 6, "height": 4 } } } ``` Returns all available rates. Then buy a specific rate to generate the label: ``` POST https://api.easypost.com/v2/shipments/{id}/buy { "rate": { "id": "rate_xxx" } } ``` Returns the label URL, tracking number, and tracking URL. SDKs available for Python, Ruby, Node.js, PHP, Java, C#, and Go. **Pricing** - **Free**: 100 tracker updates/month, 1000 API calls. No credit card required. - **Growth**: $10/month for higher limits - **Scale/Enterprise**: Custom pricing for high volume Beyond the platform fee, actual shipping costs are charged when labels are purchased โ€” at EasyPost's pre-negotiated carrier rates. **Nigerian Relevance Scenarios** Although EasyPost does not cover Nigeria domestically, it is valuable in these scenarios: 1. **Nigerian-American E-Commerce**: An entrepreneur in the Nigerian diaspora selling from the US needs to ship to US customers. EasyPost is the fastest way to integrate USPS, UPS, and FedEx with negotiated discounts. 2. **Nigerian Companies with US Fulfillment**: Some Nigerian brands use US-based third-party logistics (3PL) warehouses for US customers. EasyPost integrates with most US 3PL platforms. 3. **Nigeria-to-International via US Intermediary**: A Nigerian exporter shipping through a US-based intermediary (a forwarder or consolidator) can use EasyPost for the US-side outbound leg. 4. **UK/Australia Operations**: Nigerian businesses with UK or Australian operations can use EasyPost for those markets. **Compliance** EasyPost is SOC 2 Type II certified. API calls are encrypted via HTTPS. For high-volume shippers, EasyPost provides volume commitment programs with additional rate discounts. **Company Background** EasyPost was founded in 2012 in San Francisco by Jarrett Streebin. The company is bootstrapped and profitable, rare in the startup ecosystem. EasyPost processes hundreds of millions of shipments annually and has grown to serve thousands of e-commerce businesses ranging from small Shopify merchants to large enterprises. Their API is widely regarded as the most developer-friendly shipping API available for Western markets, with excellent documentation, consistent uptime, and responsive support. For Nigerian developers building for Western markets, EasyPost is the leading choice. For Nigerian domestic logistics, use the Nigerian-specific APIs (GIG, Sendbox, Kwik, Konga Logistics) instead.

NumlookupAPI Phone Validation

NumlookupAPI Phone Validation

NumlookupAPI is a phone number lookup and validation API providing real-time carrier identification, line type detection, geographic location data, and number format normalization for global phone numbers including Nigerian (+234) numbers. Operated by EverAPI (everapihq), the platform offers a developer-friendly integration path with a free trial requiring no credit card, paid plans from $9.99/month, and a 99.99% uptime SLA on all paid tiers. The API is designed for businesses that need to validate phone numbers at point of entry, enrich CRM contact data, or screen registrations for invalid or suspicious numbers โ€” without the complexity of a full communications platform. ## What the API Does A single NumlookupAPI call accepts a phone number and returns: - **Validity**: Whether the number is a valid, recognized phone number. - **Number (E.164)**: The number in international E.164 format. - **Carrier**: The mobile network operator (e.g., MTN Nigeria, Airtel Nigeria, Globacom, 9mobile). - **Line type**: Mobile, landline, VoIP, or unknown. - **Location**: Country and sub-national region associated with the number prefix. - **Country code**: ISO 2-letter country code (NG for Nigerian numbers). The API integrates with CRM systems, marketing platforms, and custom applications for automated phone number quality management. ## How Developers Use It GET request to the NumlookupAPI endpoint with the phone number and API key. The response is a JSON object with all available metadata. SDKs and client libraries are available for popular languages through the GitHub repository (everapihq/numlookupapi). Integration is straightforward and can be completed in under an hour. ## Pricing & Fees - **Free trial**: Available with no credit card required for initial testing. - **Paid plans**: Start at $9.99/month providing 7,000 API requests per month. - **Custom plans**: Available for businesses requiring more than 300,000 requests per month. - All paid plans include unlimited API connections (no concurrent request limit) and the 99.99% uptime guarantee. ## Authentication API key authentication. The key is passed as a parameter in the API request. Keys are issued immediately after registration. ## Rate Limits Rate limits are based on monthly request quotas per plan tier. Paid plans come with unlimited concurrent API connections โ€” requests are processed without queuing. Monthly quotas reset each billing cycle. ## Compliance NumlookupAPI processes phone numbers for validation and lookup purposes. Data handling policies are consistent with standard API service agreements. For Nigerian deployments, the carrier and format data returned supports phone number verification as part of broader user onboarding flows. ## Challenges & Gotchas for Nigerian Developers 1. **No SIM Swap detection**: NumlookupAPI provides carrier and line type data but does not offer SIM Swap detection for fraud prevention. Use Twilio Lookup for SIM Swap signals. 2. **Carrier accuracy with MNP**: Nigerian mobile number portability can cause carrier misidentification after a user switches networks. The API reflects original carrier assignment. 3. **7,000 requests at $9.99**: This is a reasonable starting volume but will be exhausted quickly for apps with active daily registrations. Plan your tier based on expected daily validation volume. 4. **USD billing**: NumlookupAPI charges in USD. Nigerian developers need a USD-capable payment method. 5. **Limited documentation depth**: As a smaller API provider, documentation and community support resources are more limited than Twilio or Abstract API. ## Company Background NumlookupAPI is operated by EverAPI (everapihq), a developer-focused API company providing a portfolio of data enrichment and validation APIs. The platform is available as an open-source client library on GitHub and through the Rapid API marketplace in addition to the main website. ## Frequently Asked Questions **Q: Does NumlookupAPI support Nigerian phone numbers?** A: Yes. Nigerian numbers (+234) are supported with carrier identification for MTN, Airtel, Glo, and 9mobile. **Q: Is a credit card required to try the API?** A: No. A free trial is available without credit card details. **Q: What is the uptime guarantee?** A: Paid plans include a 99.99% uptime SLA over the trailing 12-month period. **Q: How many requests does the entry-level plan include?** A: The $9.99/month plan includes 7,000 API requests per month.
