  note: >-
    Captures API Evangelist's additions without mutating the provider's contract. The upstream document is
    saved verbatim at openapi/_original/aeternity-node-openapi.json exactly as served by
    https://mainnet.aeternity.io/api on 2026-09-12; the refined copy differs from it only in servers[],
    where the relative "/v3" was resolved to the absolute public mainnet and testnet gateways.

  update:
    x-authentication:
      scheme: none
      note: No securityScheme is declared and none is required; write authority is the signature inside the transaction payload.
    x-state-version-header:
      name: X-Ae-Height
      note: Present on every response including errors; a lower bound on the chain height the answer reflects, comparable across nodes.
    x-backpressure:
      status: 503
      header: Retry-After
      applies_to: all operations
- target: $.paths['/transactions'].post
  update:
    x-agentic-access:
      action_class: write
      consequence: irreversible
      note: >-
        The only chain-state write on this API. Once included in a micro block the effect is final — no
        refund, void or reverse operation exists. Replay safety comes from the signed account nonce, not
        from an Idempotency-Key. Fetch GetAccountNextNonce before signing.
      reversal: DeleteTxFromMempool (node-operator only, and only while the transaction is still pending)
- target: $.paths['/dry-run'].post
  update:
    x-agentic-access:
      action_class: rehearsal
      consequence: none
      note: >-
        Executes unsigned transactions against real state and returns a gas estimate without submitting.
        Unsupported for GAMetaTx, PayingForTx and OffchainTx; 403 when the node's gas cap is exceeded.
- target: $.paths['/node/operator/mempool/hash/{hash}'].delete
  update:
    x-agentic-access:
      action_class: write
      consequence: reversible-window
      note: >-
        Removes a pending transaction from THIS node's mempool only, and only before inclusion. Not exposed
        on the public mainnet gateway; removing it locally does not remove it from other nodes' mempools.
