}ramsSetExecutorAction. signerAddress must be the AgentExecutor owner; the operation is always client-signed.
Pass either selector (4 bytes) or its left-aligned bytes32 action, then set the ActionSpec fields: supported, hasAmount, and amountIndex when the action carries value.
hasAmount: false bypasses mandate transaction and cumulative caps. Use the correct zero-based ABI word index.Next step
Preparing does not touch the chain. The response gives youtxId, the unsigned transactions, and an x402Requirements quote.
Choose who broadcasts
client-signed (the default) — you sign the transaction and Brickken broadcasts it. client-broadcast — you sign and broadcast it yourself, then confirm with txHash. Either way the operation price is split evenly: half at prepare, half at send.Submit it and settle the payment
POST to /send-transactions. The first attempt answers 402 Payment Required; read PAYMENT-REQUIRED, sign the payment locally, and retry with X-PAYMENT. An x-api-key is accepted here instead of paying.Poll until it confirms
GET /get-transaction-status with the txId. Your payment settles only after the operation confirms, and is released if it reverts.Authorizations
Base64-encoded x402 payment payload. Supported for x402-eligible agentic methods on /x402/... facades, /prepare-transactions, and eligible /send-transactions retries.
Body
Target operation chain ID. RAMS is available on Ethereum Sepolia (11155111) only at launch. Decimal and 0x hex values are accepted.
"11155111"
"0xaa36a7"
MUST be the AgentExecutor owner (pre-checked on-chain). Never brickken-relayed.
^0x[a-fA-F0-9]{40}$Whether the selector is executable through this executor.
Whether the calldata carries a value amount that must be checked against the mandate caps.
4-byte function selector to register, e.g. 0x23b872dd for transferFrom. Provide either selector or action.
^0x[a-fA-F0-9]{8}$Alternative to selector: a left-aligned bytes32 action (bytes 4..31 must be zero); the server extracts the first 4 bytes.
^0x[a-fA-F0-9]{64}$Required when hasAmount is true: zero-based index of the amount word in the calldata (uint8). E.g. 2 for transferFrom(from, to, amount). Ignored (0) when hasAmount is false.
0 <= x <= 255Optional AgentExecutor contract override; defaults to the chain's configured (platform) RAMS AgentExecutor address. Executors are per-principal — pass the principal's executor here.
^0x[a-fA-F0-9]{40}$Optional explicit gas limit.
Optional explicit transaction nonce when managing nonces manually.
Optional owner attribution email.
Alias for ownerEmail where supported.
Response
Prepared unsigned transaction payload.
