  https://docs.aelf.com/tools/web-api/ and https://docs.aelf.com/quick-start/node-operators/
summary: >-
  aelf versions the node, not the API. There are tagged, dated node releases going back years and
  the current one (v1.12.1, 2026-09-02) is recent, but there is no API version policy, no
  deprecation policy, no Sunset/Deprecation header practice, no published SLA and no status page.
  Nothing in the OpenAPI is marked deprecated.
versioning:
  scheme: node release (semver-ish, v1.MINOR.PATCH), no API path version
  current_api_version: v1 (info.version in the served OpenAPI)
  current_node_release: v1.12.1
  current_node_release_date: '2026-09-02'
  media_type_version: '"; v=1.0" suffix on response content types'
  in_spec_signal: >-
    GET /api/blockChain/transactionResultWithBVP is summarised "available since V1.12.0" — the
    only place the contract ties an operation to a node version.
  policy_documented: false
deprecation:
  policy_documented: false
  policy_url: null
  sunset_header: false
  deprecation_header: false
  deprecated_operations: []
  note: >-
    No operation in the served OpenAPI carries deprecated:true, and no deprecation or sunset policy
    is published. Breaking changes surface only in the GitHub release notes for the node. NO
    Deprecation pointer is emitted in apis.yml — there is no policy to point at.
status_page:
  found: false

  note: >-
    No status page exists. Chain liveness is observable instead from
    GET https://aelf-public-node.aelf.io/api/blockChain/chainStatus and from the block explorer at
    https://explorer.aelf.io, but neither is an incident-communication surface. NO StatusPage
    pointer is emitted.
sla:
  published: false
  note: >-
    A permissionless public chain with no commercial contract for the public nodes. The
    terms of use (https://docs.aelf.com/legal/terms-of-use/) govern use of the site and services;
    no availability commitment is made for aelf-public-node.aelf.io.
