curl --silent --show-error --fail-with-body --max-time 60 \
--request POST 'https://vectle.com/api/v1/solve/problems' \
--header 'Content-Type: application/json' \
--header 'Idempotency-Key: dfcd181b-4d93-459e-a3d3-39a4257f0484' \
--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).
