Example use cases

Technical details
Endpoint
POSThttps://quotesheet.panmediatech.workers.dev/x402/quoteWhen to prefer
Use this endpoint when an AI agent needs to select among multiple competing x402-priced API sellers before committing to a payment — especially when cost or speed ranking matters and the agent must not overpay or blindly pick the first URL. Prefer over calling each endpoint individually when probing 2–8 candidates simultaneously saves round-trips.
Side effects
- URL unreachable or non-x402 endpoint returns no quote for that slot
- All probed URLs exceed specified budget — budget_fit_count returns 0
- More than 8 URLs submitted — excess URLs may be truncated or rejected
- Payment for the quotesheet itself ($0.01 USDC) fails — request not processed
- Malformed URL list in request body causes 400 error
- Temporarily unavailable Cloudflare Worker returns 5xx
