Agent Failure Mode Registry

The Agent Failure Mode Registry (AFMR) is a reputation-integrity standard for agentic commerce. AFMR 1.0 is a published, citable vocabulary of 32 permanent failure-mode families in eight classes describing how autonomous agent systems fail as designed mechanisms; afmr.ai is the independent public front door and machine-discovery router for it. The site publishes a read-only Discovery API described by an OpenAPI 3.1 document (CC BY 4.0), a public read-only MCP server (Streamable HTTP at /api/rpc, listed in the official MCP Registry as ai.afmr/discovery), an A2A 1.0 agent card and JSON-RPC endpoint, llms.txt / llms-full.txt, a Reputation Attestation Working Draft 0.1 (human spec, JSON Schema 2020-12, verifier requirements), a pinned governance-and-voting binding, an intentionally empty endpoint-conformance registry and a configuration-only Lift Evidence index. The AFMR 1.0 vocabulary itself is governed from the editor's GitHub machine index and is not mirrored on afmr.ai.

Agent Failure Mode Registry publishes 17 API contracts indexed on the APIs.io network, including A2a API, Agents.json API, Changelog.json API, and 14 more. Tagged areas include Company, AI Agents, Agent Governance, Standards, and Reputation.

Agent Failure Mode Registry’s developer surface includes documentation, API reference, getting-started guide, changelog, GitHub presence, authentication, and 31 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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):

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)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

5 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. This rating is computed from the provider profile at artifacts.apis.io/afmr-ai/apis.yml: open an issue on github.com/api-evangelist/afmr-ai to ask a question or point us at an artifact you publish.

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
AI Agents (A2A agent cards)	undeclared	-	1	1

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.
