Technical details
Endpoint
GEThttps://fetchgate.dev/v1/buy/x402-quickstart-2026-08-23?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to programmatically purchase the specific 'x402-quickstart-2026-08-23' digital product from Fetchgate using USDC via the x402 HTTP payment protocol, with no account or prior registration required. Prefer this over card-checkout alternatives when the agent has an x402-compatible wallet and needs a fully automated, no-human-in-the-loop purchase flow.
Side effects
- Payment insufficient or rejected — x402 payment header missing or USDC amount wrong, returns 402 Payment Required
- Product not found — invalid product ID path results in 404
- Download URL expired — the signed URL has a 15-minute TTL; agent must download promptly
- Network or gateway error — 500/503 if Fetchgate infrastructure is unavailable
- Duplicate payment attempt — non-idempotent; re-purchasing incurs another $7 charge
