## Known failure modes

- Missing or invalid input parameters resulting in a 400 error
- Payment not processed correctly via x402 protocol, blocking job creation
- Job queued but never completes due to downstream processing failure
- Returned job_id cannot be used to retrieve results if polling endpoint is unavailable
- Category or plan type not supported, resulting in an empty or error response

## How this service works

Instant, low-cost Amazon, Walmart, Shopify, and eBay listing, upload-preparation, advertising, and image-brief deliverables.

## Output

Returns a job_id and a status of 'queued', indicating that the referral fee discount plan generation has been submitted asynchronously. The agent should poll or await a follow-up response to retrieve the completed plan deliverable.
