Aelf

aelf (styled lowercase by the company, listed on the secondary market as "Aelf Inc") is a Singapore-headquartered AI-enhanced, cloud-native layer-1 blockchain network founded in 2017. It is written in C# with a modular multi-side-chain architecture, parallel transaction execution and built-in cross-chain communication. Its public machine-readable surface is the AElf node Web API — an OpenAPI 3.0.1 contract every node serves at /swagger/v1/swagger.json and reachable anonymously on the public mainnet nodes — alongside 89 published protobuf contract definitions (the ACS contract standards, plus the gRPC peer and cross-chain services), six first-party chain SDKs, the aelf-command CLI, and a first-party agent layer of packaged Agent Skills and a local MCP server.

Aelf publishes 2 APIs on the APIs.io network: Node Web API and Agent Gateway API. Tagged areas include Company, Blockchain, Layer 1, Web3, and Smart Contracts.

Aelf’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, CLI, authentication, and 32 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/aelf-inc: open an issue to ask a question, or submit a pull request to add artifacts.

  note: The harvest row came from the Forge Global secondary-market listing https://forgeglobal.com/aelf-inc_stock/ ("Aelf",
    Enterprise Software). That page sits behind a Cloudflare interstitial and returned HTTP 403 to every fetch on 2026-09-09,
    so the mapping to aelf was made from the company name and sector rather than by reading the listing itself. No other company
    trading as "Aelf" was found. Every artifact in this repository was harvested from aelf.com, docs.aelf.com, the *.aelf.io
    node hosts and the AElfProject GitHub organization — never from the Forge page.

    a locally or privately run gateway. aelf operates no public instance, so there is no production host to record; this is
    a genuinely local base, not a placeholder.
