authentication:
  style: api-key-header
  header: X-Access-Key
  description: >-
    Client-side requests use a project access key in the X-Access-Key header; server-side/admin
    requests use an HTTP Bearer JWT (service token / secret) via the Authorization header.

transport:
  protocol: webrpc (JSON-RPC-over-HTTP)
  method: POST
  path_pattern: /rpc/<Service>/<Method>
  content_type: application/json
  note: all operations are POST regardless of read/write semantics
pagination:
  style: page-object (hybrid offset + cursor)
  request_field: page
  request_params: [page, pageSize, column, before, after, sort]
  response_field: page
  response_params: [page, pageSize, more, totalRecords, column, before, after, sort]
  description: >-
    List endpoints accept and return a `page` object. `page.more` signals additional results;
    `after`/`before` carry cursor tokens for column-based pagination and `page`/`pageSize`
    support offset pagination.
idempotency:
  supported: false
  note: >-
    Sequence webrpc APIs do not document an idempotency-key header. Transaction submission
    idempotency is handled at the wallet/relayer layer via nonce management, not an HTTP idempotency key.
error_envelope:
  shape: {error, code, msg, cause, status}
  format: webrpc
  artifact: errors/horizon-blockchain-games-error-codes.yml
rate_limiting:
  signal: HTTP 429 ErrorRateLimited (code 2005)
  note: compute/credits-based quotas enforced per project; see Builder plan tiers
versioning:
  scheme: sdk-semver
  note: >-
    HTTP APIs are unversioned webrpc endpoints; the SDKs (0xsequence, go-sequence, sequence-unity,
    sequence-unreal) are semver-versioned and are the primary versioned surface.
