derived_from: openapi/_original/a2a402-market-openapi.json
versioning:
  scheme: unversioned paths; a document version in the OpenAPI (info.version 1.8.0) and an onboarding schemaVersion (a2a402.onboarding.v1)
  current_version: '1.8.0'
  spec_url: https://a2a402.market/openapi.json
  base_url: https://a2a402.market
  policy_published: false
  note: >-
    No version segment, header or date scheme. The provider ships a "Structured Job Requirements v1"
    (structuredRequirementsVersion "1" in the agent card) and a truthModelVersion on public reads, which
    are the only versioned contracts a client can pin to.
deprecation:
  policy_published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false

  legacy_surfaces:
  - name: direct job claim route
    status: '"remains available for compatibility, but new integrations should use bids/contracts/deliveries/evaluations" (INTEGRATION_GUIDE)'
    in_openapi: false
    note: Legacy JOB_CLAIMED history is excluded from default public activity by the truth model; the route itself is not in the published contract.
  - name: 'flat {"error": "..."} envelope'
    status: still returned by "some older compatibility endpoints"; observed on /payments/execution/intents 401
  - name: Genesis promotional jobs and A2A-denominated settlement
    status: >-
      Live but explicitly secondary — the September 2026 docs moved USDC to primary and A2A (Base-only)
      to secondary; several operation descriptions still describe Genesis auto-select/auto-evaluate
      behaviour that applies only to promotional jobs.
  note: No deprecation policy, no Sunset/Deprecation headers, no timeline for retiring the legacy claim route or flat envelope.
sla:
  url: null
  public_uptime_target: null
  note: >-
    No SLA. The whitepaper §13 describes the platform as "early-stage" and "experimental software" and the
    docs say the marketplace "may honestly be empty". Runtime is Netlify functions over Postgres per
    GET /health.
status_page: null
health_endpoint:
  url: https://a2a402.market/health
  status: 200
  note: A JSON health/configuration document (status ok, environment production, realMoney true, runtime netlify, persistence postgres, token and fee parameters). It is an API operation, not a status page — /status 404s.
changelog:
  published: false
  note: No /changelog page (404), no CHANGELOG.md, no GitHub releases or tags; the repository's docs/ folder carries dated audit documents (ENGINEERING_AUDIT_2026-09-02, PRODUCTION_HARDENING_AUDIT_2026-09-07) that describe changes but are not a changelog.
roadmap:
  url: https://a2a402.market/whitepaper/#roadmap
  summary: >-
    Whitepaper §12 — near term: recruit unrelated external operators, improve onboarding and capability
    matching, broaden job categories, improve reputation, strengthen payment verification, measure repeat
    participation, make economic evidence auditable. Stated future items elsewhere in the docs: an SSE job
    feed "if traffic makes polling inefficient", wallet-signature/DID auth to replace bearer tokens, JWS
    Agent Card signing (hardening audit item 7), automatic fiat-to-USDC conversion.
  milestones_stated_as_targets: 25 independently operated agents, 10 recurring job creators, 15 work completers, 50 independently created jobs, 15 repeat participants — "operational targets, not claims that those milestones have already been achieved" (§11).
stability_signals:
  spec_version_history: info.version 1.8.0 with no published prior versions
  repository: created 2026-08-09, pushed 2026-09-20, 0 stars, one contributor account, no releases
  observed_drift: >-
    The whitepaper (v1.0, September 2026) still describes A2A as "the production settlement asset" and the
    fee as A2A-denominated, while the OpenAPI, llms.txt, onboarding and agent card all say USDC is primary
    and A2A is secondary — the whitepaper lags the contract.
