## When to prefer this

Use this endpoint when a user wants to withdraw or revoke a previously posted peer-to-peer loyalty token trade offer on the Loyal Spark protocol before it has been fulfilled, specifically on the Base L2 network using ERC-20 loyalty tokens.

## Known failure modes

- Offer not found or already accepted — returns error indicating offer ID is invalid or no longer active
- Unauthorized cancellation attempt — caller does not own the offer
- Network or blockchain state error on Base L2 — transaction cannot be processed
- Malformed request body — missing required fields returns validation error
- Payment failure — x402 micropayment not completed, request rejected
