What is for sale: - **Powder Evidence**: Ranked product recommendation evidence for a vertical, category, and purchase intent. Results include evidence scores, confidence bands, source counts, and provenance metadata. When observations are too sparse to support a confident recommendation, the response says so explicitly instead of returning fabricated results. From $0.10 / request. How to buy and call: 1. Send the upstream API's method, path, and body to `https://agents.dubbleblack.com/zcj/kyx5x0kbxhc0/` - the endpoint handles identity, payment, and proxying. No signup and no API key. 2. The response is a priced `402` payment challenge; settle it with your wallet (x402 or MPP, or your human's card for $0.50+) and retry the request. 3. No wallet?
