KYC verification endpoint on Base, paid per-call via x402 with USDC.
What it does
This endpoint at lowpaymentfee.com provides a KYC (Know Your Customer) verification service accessible at `/api/v1/kyc/verifications/25`. It uses the x402 payment protocol, accepting USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to access the resource.
The broader lowpaymentfee.com platform offers a suite of pay-per-call 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 priced at $0.02 per request and settle on the Base network using USDC.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what the KYC verification endpoint expects as input or returns as output. The endpoint is live (returns a proper 402 challenge), but the lack of documentation makes it difficult to use without experimentation.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is zero documentation on request format, response schema, or what the KYC verification actually checks. No OpenAPI spec, no examples, and all doc pages are empty. The specific path segment '/25' is unexplained. This is effectively a stub listing.
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 and output formats are unknown.
- —The path segment '/25' in the endpoint URL is unexplained — it may refer to a specific verification type or record ID.
- —KYC/identity verification is a regulated category; verify the provider's compliance posture before relying on this service.
- —The endpoint description 'Premium API Access' is generic and does not describe the actual KYC functionality.
