Self.ID

Self.ID is a Ceramic-based decentralized identity framework providing SDK packages and REST-compatible APIs for managing DID profiles, verifiable credentials, and self-sovereign identity data on the Ceramic network. It supports Ethereum-based authentication via 3ID Connect and enables reading and writing identity records such as basic profiles, linked crypto accounts, and linked Web2 accounts. The SDK is organized in layered packages (core, web, react, framework) targeting both Node.js and browser environments.

Self.ID publishes 8 API contracts indexed on the APIs.io network, including Commits API, Multiqueries API, Node API, and 5 more. Tagged areas include Decentralized Identity, DID, Ceramic, Self-Sovereign Identity, and Web3.

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

Self.ID’s developer surface includes engineering blog and 5 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
LF Decentralized Trust (Hyperledger) Members and Projects (enterprise blockchain, digital identity, CBDC)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
