It is part of a broader platform that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.\n\nThe specific endpoint probed (`/api/v1/kyc/verifications/48`) 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, since USDC uses 6 decimals). The platform's landing page confirms a flat $0.02/request pricing model across its API catalog, with no API keys, no rate limits, and no minimum commitments required.\n\nDocumentation is extremely sparse — the docs, pricing, API, 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 accepts or returns. The endpoint path includes an ID (`48`), but it is unclear whether this refers to a specific verification record, a verification type, or something else. Users should expect to experiment or contact the provider for integration details.","tags":[],"capabilities":["kyc-verification","x402-payment","usdc-settlement","base-network","per-call-pricing","json-response","post-method"],"categories":["identity","compliance"],"synonyms":["KYC API","identity verification","know your customer","KYC check","identity validation","compliance verification","x402 KYC"],"warnings":["No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content.","No OpenAPI or request/response schema provided; input format is unknown.","The endpoint path includes an ID (48) whose meaning is unclear — it may not be a general-purpose KYC endpoint.","KYC/identity verification is a regulated category; verify the provider's compliance posture before use."],"endpointUrl":"https://lowpaymentfee.com/api/v1/kyc/verifications/48","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/48","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 accepts.
