MUJ428

MUJ428 LLC operates the MUJ428 Trust Layer ("VERIFY BEFORE ACT"), a machine-native trust preflight service for autonomous agents: an agent POSTs the consequential action it is about to take (PAY, BUY, DELEGATE, TRUST, ACCEPT, APPROVE, WRITE, RELEASE, COMMIT, PROPOSE) and receives an ALLOW / VERIFY / REQUIRE_VERIFICATION / DENY decision plus a portable Trust Receipt v1.3, while the caller keeps execution authority and MUJ428 never moves funds. The first 1,000 qualifying decisions per caller_ref are free with no account, key or wallet; paid continuation and the evidence-signal, reputation-check, milestone-attestation, trust-report and transaction-assurance services are settled in USDC on Base (eip155:8453) through x402. The same surface is published as a 24-operation OpenAPI 3.1 REST facade hosted on Supabase edge functions, a remote Streamable-HTTP MCP server listed in the official MCP registry, an A2A agent card with a Trust Reflex extension, an RFC 9727 api-catalog, an llms.txt, AGENTS.md and a tarball-distributed JavaScript client, all discoverable from agents.muj428.com.

MUJ428 publishes 23 API contracts indexed on the APIs.io network, including Compatibility API, Discover API, Evidence Signal API, and 20 more. Tagged areas include Agents, Agent Trust, Agentic Commerce, A2A, and MCP.

MUJ428’s developer surface includes documentation, API reference, getting-started guide, FAQ, pricing, authentication, changelog, and 25 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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):

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
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's
Protected Resource Metadata +5 pts — a served /.well-known/oauth-protected-resource carrying `resource` (documented), and naming its authorization_servers (verified)

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
x402 Micropayments & Agentic Pay-per-Call	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.

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.

x402

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
