Terminal 3

Terminal 3 (T3) is a data-freedom and decentralized-identity company (founded 2023, Hong Kong) building privacy-preserving identity, verifiable credentials, and confidential computing infrastructure. Its products include T3 Verify (enterprise KYC/AML with real-time identity and liveness verification across 190+ countries and reusable verifiable credentials), T3 Identity (full-stack digital identity with passwordless auth, OpenID Connect SSO, decentralized identifiers, and verifiable credentials), Agent Command (secure, cryptographically verifiable AI-agent identity, permissions, and audit), and the T3 Network (T3N) — a hardware-secured confidential-computing network running tenant TEE contracts inside Intel TDX enclaves. Terminal 3 publishes a REST API (DID, OpenID Connect, verifiable credentials, sub-clients, transactional email, and user data) and an Agent Developer Kit (ADK) with a first-party TypeScript SDK family. Backed by 500 Global, ConsenSys Mesh, CMCC Global, Bixin Ventures, and Cherubic Ventures.

Terminal 3 publishes 7 APIs on the APIs.io network, including DID V1 API, OpenID Connect V1 API, OpenID Connect V2 API, and 4 more. Tagged areas include Company, Identity, Decentralized Identity, Verifiable Credentials, and OpenID Connect.

Terminal 3’s developer surface includes authentication, changelog, sandbox, documentation, getting-started guide, support, engineering blog, and 24 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/terminal-3: open an issue to ask a question, or submit a pull request to add artifacts.
