$5000POST https://api.gmfarcaster.com/v1/queryReturns a source-grounded answer with citations. Requires payment: an unpaid request returns 402 advertising both rails — an x402 challenge in PAYMENT-REQUIRED and an MPP challenge in WWW-Authenticate: Payment. Retry with a signed payment header (x402) or Authorization: Payment (MPP) to receive 200. Answers are live-generated and typically take ~30s (up to ~3 minutes), so use a client read timeout of at least 180s. A literal retry of the same signed payment is safe — the server recognizes it and replays the original answer rather than charging twice — but a client that gives up and constructs a NEW payment for the same question will be charged again; avoid that rather than relying on retry logic.
