This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
Lido — Ethereum liquid staking protocol (stETH / wstETH); #1 liquid staking provider by TVL.
Lido is the leading liquid staking protocol on Ethereum. Users deposit ETH and receive stETH, a rebasing ERC-20 that earns daily staking rewards, or its wrapped non-rebasing form wstETH that flows freely across DeFi. The protocol is governed by the Lido DAO via the LDO token, with on-chain Aragon voting, off-chain Snapshot signaling, and a Dual Governance timelock giving stETH holders a dynamic veto over the DAO.
Lido's validator set is delegated across multiple Staking Modules — the Curated Module of professional node operators, Simple DVT (Obol + SSV), the permissionless Community Staking Module backed by bonded stETH, and stVaults for tailored modular setups. With over $18B TVL and 8.8M+ ETH staked, Lido is the #1 liquid staking provider by total value locked.
Lido previously operated on Polygon (stMATIC, sunset June 2025) and Solana (stSOL, sunset February 2024); the protocol is now Ethereum-only.
