It is part of a broader suite of pay-per-request APIs hosted at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance/Web3 market data, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.\n\nThe specific endpoint at `/api/v1/tokens/FLOW/price` accepts POST requests and returns JSON. Each call costs $0.02 in USDC (maxAmountRequired of 20,000 base units with 6 decimals). There are no API keys, no rate limits, and no subscription commitments — you pay per request by attaching an X-PAYMENT header with a valid x402 payment proof. The payment is sent to the on-chain address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using the USDC contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base.\n\nDocumentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all resolve to a \"Connect wallet\" prompt with no additional technical detail. The response schema for this endpoint is not documented, so the exact shape of the returned price data must be inferred from usage. The site lists many other endpoints (crypto quotes, gas estimates, exchange rates, sentiment analysis, etc.) all at the same $0.02 price point.","tags":[],"capabilities":["token-price-lookup","x402-payment","usdc-settlement","base-network","pay-per-request","flow-token","crypto-market-data","json-api"],"categories":["finance","crypto"],"synonyms":["FLOW price API","FLOW token price","crypto price feed","token price lookup","Flow blockchain price","x402 crypto API","pay-per-call price API"],"warnings":["No documentation available — /docs, /pricing, and /README all return only a 'Connect wallet' prompt with no technical content.","Response schema for the FLOW price endpoint is undocumented; the exact JSON structure is unknown.","The broader site lists many endpoints but none have detailed specifications or examples."],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/FLOW/price","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/tokens/FLOW/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base).
