It uses the x402 payment protocol, accepting USDC on the Base network. Each call costs $0.02 (20,000 base units of USDC with 6 decimals). The endpoint accepts POST requests and returns JSON responses.\n\nThe broader lowpaymentfee.com platform offers a suite of pay-per-request APIs spanning data & analytics, AI & machine learning (sentiment analysis, text summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments — payment is handled entirely via the x402 protocol using USDC on Base.\n\nThe specific KYC verification endpoint's input/output schema is not documented in the crawled material. The endpoint is live and returns a valid x402 402 challenge. However, documentation pages (docs, pricing, API reference) all returned only a \"Connect wallet\" prompt with no substantive content, so the exact request format, required fields, and response structure for KYC verifications remain unknown.","tags":[],"capabilities":["kyc-verification","x402-payment","usdc-base","pay-per-request","identity-verification"],"categories":["identity","compliance"],"synonyms":["KYC API","identity verification","know your customer","AML check","ID verification","customer verification","compliance API"],"warnings":["No documentation available — all doc/pricing/API pages return only 'Connect wallet' with no content","Request and response schemas for the KYC verification endpoint are completely unknown","The endpoint path includes a specific ID (/70) whose meaning is unclear — it may be a specific verification type or a placeholder","The KYC verification endpoint is not listed among the provider's advertised APIs on the homepage, raising questions about its status"],"endpointUrl":"https://lowpaymentfee.com/api/v1/kyc/verifications/70","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/kyc/verifications/70","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 challenge, but there is no documentation for the KYC verification endpoint — no input schema, no example requests/responses, and all doc pages are empty.
