All endpoints are pay-per-request at $0.02 each, settled in USDC on the Base network. No API keys, rate limits, or upfront commitments are required — callers simply attach an x402 payment header to each request.\n\nThe specific endpoint at `/api/v1/accounts/96` is listed as \"Premium API Access\" and returns a 402 challenge requesting up to 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. The payment scheme is \"exact\" with a 300-second timeout. The endpoint accepts POST requests and returns application/json.\n\nThe broader platform advertises endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, token quotes, gas estimates, geocoding, validation, conversion, and generation. However, documentation pages (/docs, /pricing, /api, /README) all returned only a \"Connect wallet\" prompt with no substantive content, so the actual behavior and response schemas of these endpoints remain undocumented. The specific functionality of the `/api/v1/accounts/96` endpoint is unclear from available materials.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","json-response","no-api-key","post-method"],"categories":["api-platform","infrastructure"],"synonyms":["low payment fee","x402 API","pay per call API","USDC API","Base network API","micropayment API","402 payment API"],"warnings":["The specific functionality of /api/v1/accounts/96 ('Premium API Access') is not documented anywhere in the crawled material.","All documentation pages (/docs, /pricing, /api, /README) returned only 'Connect wallet' with no substantive content.","No OpenAPI spec, response schema, or example payloads are available — integration requires trial and error.","The platform lists many endpoint categories (AI, finance, analytics, etc.) but none have documented input/output schemas."],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/96","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/accounts/96","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, but there is no documentation, no OpenAPI schema, no example requests or responses, and the actual functionality of /api/v1/accounts/96 is completely unclear.
