Question 1

What does Ankr do?

Accepted Answer

Ankr is a Web3 infrastructure platform offering both free public RPC endpoints and premium dedicated node services for over 50 blockchains. Founded in 2017 and headquartered in San Francisco, Ankr operates a globally distributed network of blockchain nodes across multiple cloud providers and bare-metal servers, with a philosophy of decentralized infrastructure that reduces dependence on single providers. For Nigerian Web3 developers, Ankr is particularly valuable for its free public RPC endpoints that require no API key — making it the fastest entry point to multi-chain blockchain connectivity for development, testing, and early production use.

The free public RPC endpoints are Ankr's most accessible offering. Developers can access Ethereum, Polygon, BNB Smart Chain, Avalanche, Fantom, Arbitrum, Optimism, Solana, and dozens of other chains without registering an account or obtaining an API key. The public endpoints are shared among all users and subject to shared rate limits, but they provide immediate connectivity for development work, hackathon projects, and low-traffic applications. For a Nigerian blockchain developer starting out, being able to connect to any major chain in seconds by simply specifying the Ankr public RPC URL in their Web3 library is a significant convenience.

Premium endpoints provide dedicated node access with substantially higher rate limits, lower latency from dedicated infrastructure, and SLA-backed uptime guarantees. Premium accounts at Ankr are significantly less expensive than Alchemy or QuickNode for equivalent throughput on many chains, which has made Ankr popular for cost-conscious Nigerian teams scaling to production. Premium endpoints receive a unique API key embedded in the endpoint URL, isolating traffic from the public shared pool.

Advanced APIs built on top of the node infrastructure provide pre-indexed blockchain data similar to Moralis — NFT API for wallet NFT portfolios, Token API for ERC-20 balances, and Query API for historical blockchain data. These enhanced endpoints are available on premium plans and eliminate the need for custom data indexing for common Web3 data patterns.

The breadth of 50+ supported chains is one of Ankr's strongest selling points. Beyond the major EVM chains, Ankr supports many emerging chains (Gnosis, Celo, Aurora, Klaytn, Moonbeam, Telos, and many others) that are not covered by all node providers. For Nigerian Web3 developers exploring newer blockchain ecosystems or building cross-chain applications that span multiple less-common chains, Ankr often provides coverage that competitors lack.

WebSocket endpoints are available for all supported chains on both public and premium tiers, enabling real-time blockchain event subscriptions for Nigerian applications requiring live data feeds, transaction monitoring, or event-driven smart contract interactions.

Ankr's decentralization philosophy extends to its node operator network — Ankr allows independent node operators to join the network and serve requests, distributing infrastructure ownership beyond a single company. This aligns with Web3 values and provides a degree of censorship resistance that centralized node providers cannot offer. For Nigerian developers building applications that prioritize decentralization as a core value, Ankr's infrastructure model is ideologically consistent.

Ankr also operates a liquid staking platform (ankrETH, ankrMATIC, etc.) that allows crypto holders to stake assets while maintaining liquidity — a DeFi product built on their node infrastructure. While this is not directly a developer API product, Nigerian developers building on Ankr's infrastructure benefit from working with a company that has deep stake in the blockchain networks they support.

Pricing for premium endpoints is competitive, with monthly plans based on request volume rather than chain count — a single subscription provides access to all supported chains at the subscribed throughput level. This bundled pricing model is advantageous for Nigerian teams needing access to many chains simultaneously without paying per-chain fees.

Question 2

How much does Ankr cost?

Accepted Answer

Ankr is free to start, with paid tiers for higher usage (freemium). Free: 30M requests/month on public RPC. Premium from $99/month. 50+ chains.

Question 3

How do I authenticate with the Ankr API?

Accepted Answer

API Key (Premium) or open public endpoint (no key)

Question 4

Is there a rate limit on Ankr?

Accepted Answer

Public: shared rate limits. Premium: dedicated endpoints, higher limits.

Question 5

Does Ankr offer a sandbox or test mode?

Accepted Answer

No public sandbox is documented for Ankr. Check the official docs for the recommended way to test integrations safely before going live.

Question 6

What is Ankr best suited for?

Accepted Answer

Web3 developers needing free public RPC access across 50+ blockchains or affordable premium dedicated endpoints for multi-chain development with decentralized node infrastructure.

Question 7

Is there anything else I should know before integrating Ankr?

Accepted Answer

Ankr provides both free public RPC endpoints (no API key, shared) and premium dedicated endpoints for 50+ blockchains. Known for decentralized node infrastructure and competitive multi-chain pricing.
