CLEAR

CLEAR (clearme.com) is a secure identity company best known for its biometric identity network. For developers, CLEAR1 exposes an identity verification API: you create a verification session, hand the user off to CLEAR's hosted UI to capture a government ID and a selfie/liveness check, then retrieve the verified result and traits. The platform supports OAuth 2.0 / OpenID Connect (with PKCE) for end-user identity tokens, bearer-key auth for the REST API, webhooks for session lifecycle events, a sandbox with synthetic test identities, and native integrations (Okta, Microsoft Entra, Ping, Amazon Connect, DocuSign, Greenhouse) across workforce, healthcare, financial services, and consumer use cases, including IAL2 identity proofing and TEFCA/Carequality access.

CLEAR publishes 1 API contract indexed on the APIs.io network: Verification Sessions API. Tagged areas include Company, Identity, Identity Verification, Authentication, and KYC.

The CLEAR catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

CLEAR’s developer surface includes engineering blog, documentation, API reference, getting-started guide, support, authentication, sandbox, and 27 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

6 more unmet checks in the Agent Readiness table above.

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.

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
RegTech, AML/KYC and Money Transmission	builds-on	46.4	-	-
Biometrics Testing (biometric recognition vendors, identity verification depth)	builds-on	46.4	-	-

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.
