spec: openapi/proofdraw-api-openapi.yml
versioning:
  scheme: uri-path
  current: v1
  spec_version: 1.0.0
  docs: https://proofdraw.com/api
  note: >-
    Version is carried in the path (/api/v1/...). GET /api/health and the public verification reads
    (/list/{hash}, /list/{hash}/ots) sit outside the version prefix, so the verification surface is not
    versioned alongside the account API. No version header, no date-pinned version, no version negotiation.
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  deprecated_operations: []
  note: >-
    No deprecation or sunset policy is published, and no operation in the OpenAPI carries
    `deprecated: true`. RFC 8594 Sunset/Deprecation headers are not documented. With v1 being the first
    and only version, there is nothing deprecated yet — but also no stated commitment about how a v2 would
    be introduced or how long v1 would run. No `Deprecation` pointer is emitted in apis.yml.
status_page:
  url: null
  note: >-
    No status page. https://proofdraw.com/status returns 404, no status.proofdraw.com subdomain resolves in
    the site's own link graph, and the sitemap lists no status URL. The nearest operational signal is the
    unauthenticated liveness probe GET https://proofdraw.com/api/health (200, `{"status":"ok","time":…}`),
    which is a probe endpoint rather than an incident-history surface. No `StatusPage` pointer is emitted.
sla:
  url: null
  uptime_target: null
  note: >-
    No SLA is published. The Terms of Service (https://proofdraw.com/terms, 200) is the only contractual
    document on the site.
changelog:
  url: null
  note: >-
    No dated changelog. https://proofdraw.com/changelog returns 404 and the sitemap lists no changelog or
    release-notes page. The GitHub account (github.com/proofdraw) carries only the MIT verifier and the
    append-only draw-lists mirror — neither publishes releases or tags. No `ChangeLog` pointer is emitted.
durability_commitments:
  - claim: Sealed draws are permanent and cannot be deleted or modified
    mechanism: >-
      DELETE /v1/draws/{id} returns 409 state_conflict once sealed; the list file is pushed to
      github.com/proofdraw/draw-lists and OpenTimestamps-attested at seal.
    source: https://proofdraw.com/api
  - claim: Verification survives ProofDraw going offline
    mechanism: >-
      "We designed this so that ProofDraw going offline wouldn't break a single verification" — the sealed
      lists are mirrored to a public GitHub repo, the randomness comes from the League of Entropy drand
      chain, and the verifier is MIT-licensed and client-side. Publicly stated design commitment on
      https://proofdraw.com/about; not an SLA.
    source: https://proofdraw.com/about
  - claim: OpenTimestamps proofs upgrade to a Bitcoin anchor within ~24h
    mechanism: background job `proofdraw:upgrade-ots`; calendar attestation is best-effort at seal time.

company_stage:
  founded: 2026
  headquarters: Michigan, USA
  note: >-
    Self-described as early ("We're early. The team is small.") on the careers section. The whole public
    surface — apis.json, sitemap, OpenAPI, terms — carries a 2026-07-13 last-modified date, and the site
    root's Last-Modified header agrees, so nothing on the public surface has changed since launch.
