  title: API Evangelist overlay for the MUJ428 Trust Layer API
  version: 1.0.0
  x-generated: '2026-09-19'
  x-method: generated
  x-source: >-
    Generated by API Evangelist against openapi/muj428-com-trust-layer-openapi.json (the provider's own
    OpenAPI 3.1.0 mirror, v1.8.2, fetched 2026-09-19 from https://agents.muj428.com/openapi.json). The
    original is never mutated; this overlay adds tags, contact/terms discovery, x402 payment semantics the
    spec states only in prose, and pointers to the sibling artifacts. Every value below is taken from a
    document the provider serves (developer.json, AGENTS.md, pricing.json, the x402 manifest, live headers).
