What it does

This endpoint at lowpaymentfee.com provides token data for FLOW via a simple POST request, paid per-call using the x402 protocol. The payment is settled in USDC on the Base network at $0.02 per request (maxAmountRequired of 20,000 base units with 6 decimals). No API keys, accounts, or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.

The endpoint is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com spanning data & analytics, AI/ML inference, finance & Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. The specific `/api/v1/tokens/FLOW` path sits within the Finance & Web3 category, likely returning token price or market data for the FLOW token.

Documentation is extremely sparse. The landing page lists available endpoints and pricing, but the /docs, /pricing, and /README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed field-level documentation available from the crawl. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the exact response schema and accepted request body fields are unknown.
