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/44`. 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 endpoint.
The broader lowpaymentfee.com platform advertises a range 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 listed 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 input the KYC verification endpoint expects or what it returns. The specific resource path includes an ID (`44`), but it is unclear whether this is a fixed resource or a parameterized path. Prospective users should expect to experiment or contact the provider for integration details.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), 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. This is effectively a stub listing.
