Pay-per-call market quote endpoint for the LOW token, settled in USDC on Base via x402.
What it does
This endpoint at lowpaymentfee.com provides a market quote for the "LOW" token via a POST request to `/api/v1/market/quote/LOW`. It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed returns a valid x402 402 challenge, confirming it is live. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). Payment is made via the x402 "exact" scheme to the specified payTo address, with a maximum timeout of 300 seconds. No API keys or rate limits are advertised; access is instant upon payment.
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint's actual response format and the data fields returned for a LOW token quote are unknown. This limits the ability to assess the quality or usefulness of the data returned.
