Ethereum

Ethereum is a decentralized, open-source blockchain platform that supports smart contracts - self-executing programs that run on its distributed network. It is the foundation for a vast ecosystem of decentralized applications (dApps), tokens, DeFi protocols, and NFTs, and uses a proof-of-stake consensus mechanism.

Ethereum publishes 1 API on the APIs.io network: Ethereum JSON RPC API API. Tagged areas include Blockchain, DeFi, Ethereum, JSON-RPC, and Smart Contracts.

The Ethereum catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Ethereum’s developer surface includes documentation, getting-started guide, engineering blog, and 9 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/ethereum: open an issue to ask a question, or submit a pull request to add artifacts.
