Execute Plan

Executes a previously created plan. The plan must have been signed by the sub-account’s signer. This triggers the actual on-chain transaction(s).

Request

POST /accounts/:account_id/plan/execute

Body parameters

Parameter	Type	Required	Description
`plan_id`	string	Yes	The plan ID returned from a plan creation endpoint
`signature`	string	Yes	EIP-712 signature over the plan’s digest (`0x`-prefixed hex)

Examples

curl -X POST https://prime-api.legend.xyz/accounts/acc_2o0yiljtp378/plan/execute \
  -H "Authorization: Bearer $LEGEND_QUERY_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "plan_id": "pln_71mcui082png",
    "signature": "0x1a2b3c4d5e6f..."
  }'

const result = await client.plan.execute("acc_2o0yiljtp378", {
  planId: "pln_71mcui082png",
  signature: "0x1a2b3c4d5e6f...",
});

result = await client.plan.execute(
    "acc_2o0yiljtp378",
    plan_id="pln_71mcui082png",
    signature="0x1a2b3c4d5e6f...",
)

use legend_client::ExecuteParams;

let result = client.plan.execute("acc_2o0yiljtp378", &ExecuteParams {
    plan_id: "pln_71mcui082png".into(),
    signature: "0x1a2b3c4d5e6f...".into(),
}).await?;

Response

{
  "plan_id": "pln_71mcui082png",
  "quark_intent_id": "qi_abc123",
  "activity_id": "act_xyz789",
  "status": "executing"
}

Response fields

Field	Type	Description
`plan_id`	string	The executed plan’s ID
`activity_id`	string	Activity ID (`act_xxx`) — use with `GET /activities/:id` to poll execution status
`quark_intent_id`	string	Intent ID (`qi_xxx`)
`status`	string	Always `"executing"` on success — the transaction has been submitted

Signing the plan

When you create a plan (earn, withdraw, or transfer), the response includes details.eip712_data.digest. This is the EIP-712 hash that the account’s signer must sign.

import { privateKeyToAccount } from "viem/accounts";

const signer = privateKeyToAccount(privateKey);
const signature = await signer.sign({ hash: plan.details.eip712_data.digest });

from eth_account import Account

signer = Account.from_key(private_key)
digest = plan["details"]["eip712_data"]["digest"]
sig = signer.unsafe_sign_hash(bytes.fromhex(digest[2:]))
signature = "0x" + sig.signature.hex()

let digest = plan.digest().expect("Plan missing digest");
// Sign with legend-signer or your own EIP-712 signer

Errors

Status	Code	Description
400	`invalid_params`	Missing `plan_id` or `signature`
404	`plan_not_found`	Plan doesn’t exist or has expired
409	`plan_stale`	Plan’s underlying data has changed — create a new plan
500	`internal_error`	Signature verification or execution failed

Notes

Plans expire after 2 minutes. If the plan has expired, create a new one.
Once executed, the plan is consumed and cannot be re-executed.
The status: "executing" response means the transaction has been submitted but not yet confirmed. Use Activities or Events to track confirmation.
The signature must come from the signer key associated with the sub-account. A signature from a different key will be rejected.
