4 Best APIs for Threat-Intelligence in Nigeria

Pulsedive is a community-driven threat intelligence API that provides enriched information about indicators of compromise including IP addresses, domain names, and URLs. The platform aggregates threat data from dozens of open-source intelligence feeds, performs active and passive scanning, and enriches each indicator with risk scores, associated threats, properties, and historical scan data to give security teams comprehensive context about potential threats. The core value of Pulsedive lies in its aggregation and enrichment capabilities. Rather than querying multiple individual threat intelligence sources and manually correlating the results, Pulsedive queries all connected feeds simultaneously and returns a consolidated risk assessment. Each indicator receives a risk score ranging from none to critical based on factors including its appearance in known malicious activity, the types of threats it has been associated with, and scan results revealing potentially malicious server configurations. The API supports lookups for three primary indicator types. IP address lookups reveal information about the hosting organization, ASN, geolocation, open ports and services discovered during active scanning, SSL certificate details, DNS records, associated domains, and any threats the IP has been linked to across threat intelligence feeds. Domain lookups provide registration information, DNS history, SSL certificate chain, associated IP addresses over time, and threat associations. URL lookups perform active scanning to analyze the page content, check for malicious redirects, identify hosting details, and cross-reference against known malicious URL databases. For Nigerian cybersecurity professionals and organizations, Pulsedive provides a particularly accessible entry point into threat intelligence because of its generous free tier. The free plan allows individual researchers and small security teams at Nigerian startups and SMEs to perform meaningful threat analysis without budget constraints. At 30 requests per day on the free tier, security analysts at Nigerian organizations can perform enrichment on the most critical indicators encountered during incident response and daily monitoring activities. Nigerian fintech companies and banks regularly encounter suspicious IPs attempting to probe their APIs and payment systems. Pulsedive enrichment transforms a raw suspicious IP address into a complete threat profile showing whether that IP has been previously associated with banking trojans, fraud operations, or botnets. This context enables faster, more confident decisions about whether an incident requires immediate escalation or can be handled as routine noise. Threat feed integration is central to Pulsedive effectiveness. The platform continuously ingests from open-source feeds including AlienVault OTX, Emerging Threats, Abuse.ch, ThreatFox, MalwareBazaar, URLhaus, Feodo Tracker, and many others. When any of these feeds marks an indicator as malicious, that information propagates into Pulsedive and becomes available through the API. For Nigerian security teams that cannot afford premium threat intelligence subscriptions, Pulsedive aggregates the best available open-source intelligence into a single API call. The API also exposes Pulsedive threat profiles, which are named threat campaigns and malware families. Security teams can query for all indicators associated with a specific threat such as a ransomware group, banking trojan, or APT actor, enabling targeted threat hunting and proactive blocking of infrastructure linked to known threat actors. Bulk indicator scanning is supported for security operations that need to enrich large lists of indicators from network logs or SIEM data. Analysts can submit lists of IPs, domains, and URLs for batch processing, with results returned in structured JSON format that can be imported into SIEM platforms or spreadsheets for analysis. For developers building security products targeting the Nigerian market, Pulsedive API integration adds immediate threat intelligence value to security dashboards, SOAR platforms, and incident response tools. The clear risk scoring and structured data format makes it straightforward to display threat context in user interfaces and trigger automated responses when high-risk indicators are detected. The combination of free access, comprehensive enrichment, and easy integration makes Pulsedive an excellent starting point for Nigerian organizations beginning to build threat intelligence capabilities.

GreyNoise is a cybersecurity intelligence API that helps security teams distinguish between targeted attacks and the constant background noise of benign internet scanning activity. Rather than alerting on every connection attempt hitting a network, GreyNoise classifies internet traffic so that security operations centers can focus their limited attention on genuine threats rather than the thousands of automated scanners, research organizations, and security companies that continuously probe the entire internet. The fundamental insight behind GreyNoise is that a large proportion of internet traffic that triggers security alerts is not actually malicious. Search engines, academic researchers, vulnerability scanners, ISPs, cloud providers, and security companies all run automated systems that systematically scan IP address ranges. When these scans hit enterprise firewalls and intrusion detection systems, they generate alerts that look identical to the early stages of a targeted attack. Analysts who must investigate these false positives waste enormous amounts of time, leading to alert fatigue and missed real threats. GreyNoise addresses this through its sensor network, which consists of thousands of IP addresses distributed globally that passively collect internet-wide scanning data. Any IP address that probes these sensors is classified based on its behavior, and that classification is made available through the GreyNoise API. When a security team queries an IP address that has been seen scanning the GreyNoise sensor network, they receive a verdict: this IP is a known internet background noise source and is likely not targeting your organization specifically. The API provides two primary datasets. The first is the GreyNoise dataset, which covers IPs observed actively scanning the internet. Each entry includes the IP address, classification as malicious or benign, tags describing what the IP was doing such as scanning for specific vulnerabilities or running specific tools, country of origin, organization, and ASN details. The second dataset is RIOT, which stands for Rule It Out, covering IP addresses associated with well-known business services such as Google, Amazon, Microsoft, and other cloud providers that appear frequently in security logs but are almost never genuinely malicious. For Nigerian security operations centers operating in Nigerian banks, telecommunications companies, government agencies, and large enterprises, GreyNoise dramatically reduces the operational burden of managing security alerts. Nigerian SOC teams frequently deal with high volumes of alerts from their SIEM systems, and a significant portion of these alerts involve IP addresses that are simply running automated internet scans with no specific interest in Nigerian targets. GreyNoise context allows analysts to quickly dismiss these false positives and focus on IPs that are engaged in targeted, suspicious behavior. The API integrates natively with major SIEM platforms including Splunk, IBM QRadar, and Microsoft Sentinel, as well as threat intelligence platforms. Nigerian organizations using any of these security tools can install GreyNoise integration apps that automatically enrich security alerts with GreyNoise classifications, reducing the mean time to investigate and close false positive alerts. Tag-based filtering is one of GreyNoise most powerful features for Nigerian security teams. When a new vulnerability is announced, GreyNoise quickly adds a tag identifying IPs that are scanning for that specific vulnerability. Nigerian security teams can query for IPs currently scanning for vulnerabilities present in their specific technology stack, enabling proactive threat hunting before an exploitation attempt actually reaches their network. GreyNoise offers a community tier with basic IP lookup functionality at no cost, making it accessible to Nigerian security researchers, independent consultants, and smaller organizations that cannot afford enterprise security intelligence subscriptions. The community API allows unlimited IP queries with basic classification data, providing immediate value for any security team that wants to begin filtering background noise from their alerts. The GreyNoise visualization and query interface allows complex boolean searches across the sensor data, enabling analysts to discover patterns in who is scanning for what vulnerabilities and from where. This bulk analysis capability is valuable for Nigerian threat intelligence teams building reports on the threat landscape facing Nigerian organizations, identifying the most active scanning activity targeting African IP address space and the vulnerabilities being most aggressively probed.

URLhaus is a free threat intelligence API by Abuse.ch that provides access to a community-curated database of malicious URLs used for distributing malware, phishing, and exploit kits. The URLhaus API allows developers and security researchers to query URLs, payloads, and tags — checking whether a URL is flagged as malicious before allowing users to visit or download from it. Security-focused Nigerian developers building browser extensions, email security tools, link shorteners, and web application firewalls use URLhaus to add real-time URL threat intelligence. The API is completely free with no authentication required for basic queries. Supports bulk URL submission for contributing to the community database.
