See [Signing](https://docs.mobula.io/rest-api-reference/endpoint/bridge-integrator-fees-claim#signing). ## Response The booked claim, in the same shape as the [balance](https://docs.mobula.io/rest-api-reference/endpoint/bridge-integrator-fees) `claims[]`: ```json theme={null} { "data": { "claimId": "6f1c2a9e-4b7d-4c1e-9a53-2d8f0e7b1c44", "status": "pending", "chainId": "evm:8453", "recipient": "0xYourFeeWallet", "amountUsd": 120.5, "networkFeeUsd": 0.0041, "receiveAmount": "120.4959", "txHash": null, "error": null, "createdAt": "2026-10-20T09:14:40.000Z", "updatedAt": "2026-10-20T09:14:40.000Z" } } ``` ## Claim statuses Follow the claim with [`GET /integrator-fees/{address}`](https://docs.mobula.io/rest-api-reference/endpoint/bridge-integrator-fees). | Status | Meaning | | - | - | | `pending` | Booked, waiting to be sent. | | `sending` | Payout being sent; `txHash` appears once it is broadcast. | | `paid` | USDC delivered. Final. | | `failed` | Nothing was paid. `error` says why, and the amount is back in `availableUsd`. Final. | A claim fails when the payout chain doesn't hold enough USDC for it right now. Claim a smaller amount or pick another `chainId`. On EVM the payout comes from the Mobula bridge contract; on Solana it is a USDC transfer from the solver wallet with the memo `claim:`. ## Errors | HTTP | `message` | | - | - | | `400` | `Signature is not …'s over the prepared message` | | `400` | `Claim expired — prepare a new one` | | `400` | `Balance no longer covers this claim — prepare a new one` | | `404` | `Unknown or expired claim — prepare a new one` | ## OpenAPI ````yaml post /2/bridge/integrator-fees/claims/{claimId} openapi: 3.0.0 info: version: 1.0.0 title: Mobula API description: >- Documentation of the Mobula API **Demo API**: The default server (demo-api.mobula.io) is a demo API with rate limits.
