The specific resource `/api/v1/kyc/verifications/86` accepts POST requests and charges up to $0.02 per call in USDC on the Base network. Payment is handled inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required.\n\nThe provider's site advertises a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request. However, the KYC verification endpoint is not listed on the provider's public landing page, and no documentation, request/response schemas, or usage examples are available for it. The docs, pricing, and API pages all resolve to a minimal \"Connect wallet\" prompt with no further content.\n\nBecause there is no published input schema, expected request body format, or sample response for this KYC endpoint, callers will need to experiment or contact the provider to understand what fields to submit and what the response looks like. The endpoint is confirmed live (returns a valid x402 402 challenge), but the lack of documentation makes integration difficult without additional information.","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","ID verification","compliance check","AML verification","customer verification"],"warnings":["No documentation available — docs, pricing, and API pages all show only a 'Connect wallet' prompt with no content.","The KYC verification endpoint is not listed among the provider's publicly advertised APIs.","No request body schema or response schema is published; callers must guess at the expected input format.","KYC/identity verification is a regulated category — verify the provider's compliance posture before relying on this for production use."],"endpointUrl":"https://lowpaymentfee.com/api/v1/kyc/verifications/86","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/86","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 challenge, but there is zero documentation on request/response schemas, no examples, and the KYC endpoint isn't even listed on the provider's own landing page.
