Example prompt: Can you cancel all my stale and unfilled loyalty token trade offers on Loyal Spark so my marketplace listings are cleaned up?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically clean up expired or unfilled peer-to-peer loyalty token trade offers on the Loyal Spark protocol. Prefer this over manual on-chain transactions when automating marketplace hygiene tasks or when integrating loyalty reward workflows via MCP/REST tooling on Base L2.

## Known failure modes

- No stale offers found to cancel — returns empty result set
- Invalid or unauthorized wallet address — returns 401/403 error
- Offer already filled or cancelled — idempotency conflict response
- Blockchain transaction failure on Base L2 — returns error with transaction hash
- Rate limit or payment failure for $0.01 USDC — returns 402 payment required
- Malformed request body — returns 400 with validation error
