ankr

Ankr is a Web3 infrastructure provider whose multichain RPC, Advanced API, liquid staking, contract automation, and Rollup-as-a-Service products serve developers, exchanges, and enterprises across 80+ blockchains. The Node API exposes JSON-RPC and WebSocket endpoints at rpc.ankr.com/{chain}; the Advanced API (AAPI) layers an indexed query surface across 19 EVM mainnets for NFT, token, and historical-data reads. Ankr also operates liquid staking pools (ankrETH, ankrBNB, ankrPOL, ankrAVAX, ankrFTM, ankrDOT, ankrFLOW), a contract automation service on BNB Smart Chain, and an enterprise Rollup-as-a-Service practice that supports OP Stack, Polygon CDK, and Arbitrum Orbit variants. Infrastructure runs as a global DePIN of bare-metal nodes in 30+ regions serving roughly 8 billion daily RPC requests.

ankr publishes 8 APIs on the APIs.io network, including EVM API, Metrics API, NFT API, and 5 more.

The ankr catalog on APIs.io includes 2 event-driven AsyncAPI specifications, 1 JSON-LD context, and 3 Spectral governance rulesets.

ankr’s developer surface includes authentication, developer portal, documentation, signup flow, pricing, engineering blog, CLI, and 39 more developer resources.

description: 'Ankr is a Web3 infrastructure provider whose multichain RPC, Advanced API, liquid staking,

  contract automation, and Rollup-as-a-Service products serve developers, exchanges, and

  enterprises across 80+ blockchains. The Node API exposes JSON-RPC and WebSocket endpoints at

  rpc.ankr.com/{chain}; the Advanced API (AAPI) layers an indexed query surface across 19 EVM

  mainnets for NFT, token, and historical-data reads. Ankr also operates liquid staking pools

  (ankrETH, ankrBNB, ankrPOL, ankrAVAX, ankrFTM, ankrDOT, ankrFLOW), a contract automation

  service on BNB Smart Chain, and an enterprise Rollup-as-a-Service practice that supports OP

  Stack, Polygon CDK, and Arbitrum Orbit variants. Infrastructure runs as a global DePIN of

  bare-metal nodes in 30+ regions serving roughly 8 billion daily RPC requests.
