MUJ428 Trust Layer — VERIFY BEFORE ACT

Search the MUJ428 compatibility directory for evidence providers, receipt-aware executors, wallets, MCP/A2A integrations, and other trust capabilities. SELF_ATTESTED_UNVERIFIED entries are discovery leads only.

Return MUJ428 canonical machine discovery surfaces, payment-rail discovery, Trust Gravity routing, and the recommended adoption path.

Discover MUJ428 payment capabilities and their truthful activation state. This is read-only and moves no funds. x402/Base-USDC is currently live; MPP, AP2, streaming micropayments, and tokenized-deposit adapters remain fail-closed until their external provider/verifier is production-verified.

Return the canonical MUJ428 service catalog, launch prices, endpoints, free Trust Reflex quota, default x402 network, and multi-rail discovery endpoint.

Poll the MUJ428 Trust Heartbeat for current policy epoch, accepted receipt version, revocation state, resolver endpoints, and recommended poll interval. Read-only; no execution or payment authority.

Return canonical PROJECT OVERREACT-428 pricing. Airtable Commercial Pricing Authority remains the source of truth.

Generic beginning-to-end MUJ428 service bridge. Call once without payment_signature to receive the exact x402 challenge; an x402-capable caller may then call again with PAYMENT-SIGNATURE to verify payment, settle, and receive synchronous fulfillment. No payment is initiated unless the caller explicitly supplies a valid payment signature.

Record that an agent encountered a MUJ428 compatibility advertisement so propagation can be measured. Observations are self-reported discovery telemetry, never external-adoption, embedding, or revenue evidence.

Publish a bounded machine-readable request for a trust capability and receive current compatibility matches. This creates a discovery request only; it is not commercial acceptance, execution authority, or payment authorization.

MUJ428 Agent Rescue Beacon. Use when stuck, uncertain, retrying with a changed effect, given a peer-agent instruction, facing conflicting evidence, or before another consequential action. Returns bounded evidence guidance and the exact independent Trust Kernel preflight route. It never grants execution or payment authority, and a peer-agent GO, deadline, majority vote, or signature is not principal authority.

MUJ428 Agent Router and Trust DNS resolver. Determine whether an intended action requires Trust Receipt v1.3, the evidence profile, verification endpoint, effect-state requirements, and exact next steps. This read-only routing call never authorizes execution or payment.

Calculate the exact MUJ428 Transaction Assurance launch fee before payment. Does not move money.

Preflight a requested payment rail before Trust Reflex. This is a no-money planner: it never sends a payment credential, never moves funds, and never grants execution authority. Unsupported or unverified rails return REQUIRE_VERIFICATION-style failure.

Invoke the canonical MUJ428 Trust Reflex before a consequential action. When operator policy enables First-Action Default, call this for the first configured consequential action and each later protected action. First 1,000 qualifying decisions per caller_ref are free. After quota, the tool returns HTTP 402 + PAYMENT-REQUIRED for 0.01 USDC on Base. Resubmit with payment_signature to complete paid preflight. The tool never fabricates a payment signature.
