Was es kann

Tool-Inventar

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.

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.

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.

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.

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.
