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 40 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ankr: open an issue to ask a question, or submit a pull request to add artifacts.

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.
