It uses the x402 payment protocol, accepting USDC on the Base network. The endpoint returns a 402 challenge requiring an X-PAYMENT header with payment proof before granting access. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD.\n\nThe broader lowpaymentfee.com platform advertises a wide catalog of pay-per-request APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/Web3 data (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no commitments required.\n\nThis specific endpoint (`/api/v1/kyc/verifications/82`) is not listed on the site's public catalog, and no documentation was found describing its input schema, required fields, or response format. The `/docs`, `/api`, `/pricing`, and `/README` pages all returned only a \"Connect wallet\" prompt with no substantive content. Without documentation or example payloads, the exact KYC verification functionality and expected request/response structure 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","compliance check","ID verification","customer verification","AML screening"],"warnings":["No documentation found for this specific KYC verification endpoint","Input schema and required fields are completely unknown","The endpoint path includes a numeric ID (82) suggesting it may be a specific resource rather than a general-purpose API","The /docs, /pricing, /api, and /README pages contain no substantive content","This endpoint is not listed in the provider's public API catalog","KYC/identity verification is a regulated category — verify the provider's compliance credentials independently"],"endpointUrl":"https://lowpaymentfee.com/api/v1/kyc/verifications/82","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/82","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no input/output schema, no examples, and the specific KYC endpoint is not even listed on the provider's public catalog.
