It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.\n\nThe specific endpoint probed (`/api/v1/kyc/verifications/94`) accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0.02 USD per request), consistent with the platform's uniform $0.02/request pricing. Payment is made via the x402 \"exact\" scheme to a specified wallet address. No API keys are required; access is granted immediately upon payment. The platform advertises no rate limits and no minimum commitments.\n\nDocumentation on the site is extremely sparse — the docs, API, 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 description of what the KYC verification endpoint actually checks or returns. The endpoint path includes an ID (`94`), but it is unclear whether this refers to a specific verification record, a verification type, or something else. Prospective users should be aware that the actual functionality behind this endpoint is unverified beyond the x402 challenge metadata.","tags":[],"capabilities":["kyc-verification","x402-payment","usdc-settlement","base-network","per-call-pricing","no-api-key","json-response"],"categories":["identity","compliance"],"synonyms":["KYC check","identity verification","know your customer","KYC API","identity validation","compliance check","customer verification"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.","No OpenAPI or request/response schema provided; input format and output structure are unknown.","The endpoint path includes an ID (94) whose meaning is unclear — it may not be a general-purpose KYC endpoint.","KYC/identity verification is a regulated category; no compliance certifications or data handling policies are documented.","Actual functionality behind this endpoint is unverified beyond the x402 payment challenge."],"endpointUrl":"https://lowpaymentfee.com/api/v1/kyc/verifications/94","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/94","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 with clear pricing, but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what the KYC verification endpoint actually does or expects as input.
