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 use the x402 payment protocol, settling in USDC on the Base network.\n\nThe specific endpoint probed (`/api/v1/kyc/verifications/46`) returns a live 402 challenge requesting up to $0.02 per call (maxAmountRequired of 20,000 base units of USDC, which has 6 decimals = $0.02). The platform advertises a flat $0.02/request pricing across all its APIs with no API keys, no rate limits, and instant access. Payment is made via the x402 `exact` scheme to a specified wallet address.\n\nDocumentation is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no additional technical content. There is no OpenAPI spec, no request/response schema documentation, and no examples available. The endpoint path suggests it may relate to retrieving or initiating a KYC verification (resource ID 46), but the exact input parameters and response format are unknown. The POST method is indicated in the outputSchema.","tags":[],"capabilities":["kyc-verification","x402-payment","usdc-settlement","base-network","pay-per-call","no-api-key"],"categories":["identity","compliance"],"synonyms":["KYC API","identity verification","know your customer","compliance check","ID verification","x402 KYC","onchain KYC"],"warnings":["No API documentation available — all doc pages render only 'Connect wallet'","No OpenAPI or request/response schema provided","The endpoint path '/api/v1/kyc/verifications/46' has a hardcoded resource ID (46) with no explanation of what it represents","KYC/identity verification is a regulated category — no information on compliance standards, data handling, or privacy policies","The platform lists many API categories but provides no evidence of actual functionality behind any of them"],"endpointUrl":"https://lowpaymentfee.com/api/v1/kyc/verifications/46","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/46","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, but there is zero documentation on request parameters, response schema, or what 'verifications/46' actually does.
