Pay-per-call cited research brief
Pay-per-call cited research brief. The request carries a query and 1 to 12 quotes with source URLs; the response is a short brief that cites only those quotes, at 0.008 USDC per call on Base. Payment settles after the brief is produced. A client nonce header makes a retry free of a second charge.
