A product question. A sourced answer.

Use the datawebot HTTP API at https://www.datawebot.com/api/product.
Read https://www.datawebot.com/docs/api/reference and https://www.datawebot.com/openapi.json before making requests.
Use DATAWEBOT_API_KEY from the owner's secret environment. Never print it or put it in a URL.
The URL below is a reserved placeholder. Replace it only with a storefront URL that the owner is authorized to use and that the service currently supports. Do not submit the placeholder.
Task: inspect the product and its reported variants, prices and availability.
Budget: at most 2 page visits and 2 credits. Do not increase it without the owner's authorization.
1. POST /estimate with the input below. Stop on validation, balance or permission errors.
2. POST /runs with the same input and a unique Idempotency-Key for this task. Preserve that key and run.id across retries; never create duplicate work after an uncertain response.
3. GET /runs/{id}. Respect next_poll_after. If action_required is present, ask the owner. Yield while Processing and resume with the saved ID.
4. When Ready, GET /runs/{id}/results and follow next_cursor until null. Stop and explain Unavailable, expired or failed results.
5. Report returned variants, currencies, source URLs, retrieval times, completeness and warnings. Null means unknown. An unavailable variant is not evidence of future stock. Do not invent missing values.
