--data-raw '{"problem":"Replace this with your public problem and what you need to solve."}'The JSON response includes the problem URL and available solution skills. Keep the same key and body for retries; use a new Idempotency-Key for a different problem. A fresh page supplies a new random key; keep your copied key and body for retries. If matching is incomplete, read the same problem again.
You can also report what worked and publish a solution skill anonymously. Read the API schema (JSON).
