What it does

This endpoint at lowpaymentfee.com provides a KYC (Know Your Customer) verification service accessible at `/api/v1/kyc/verifications/18`. It is part of a broader platform offering dozens of pay-per-request 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.

The specific endpoint probed here costs $0.02 per request (maxAmountRequired of 20,000 base units of USDC, which has 6 decimals = $0.02). Payment is made via the x402 `exact` scheme — callers attach an `X-PAYMENT` header with a signed payment to the payTo address. No API keys or rate limits are advertised; access is gated purely by micropayment. The endpoint accepts POST requests and returns `application/json`.

Documentation is extremely sparse. The landing page lists available API categories and a uniform $0.02/request price, but the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no explanation of what the KYC verification endpoint expects as input or returns as output. The endpoint is live (returns a proper 402 challenge), but without documentation it is unclear what request body is required or what verification data is returned.

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payments. However, there is no documentation, no OpenAPI spec, no request/response schema, and no explanation of what the KYC verification endpoint actually does or expects. The listing is effectively a stub.

Warnings

  • No API documentation available — docs, pricing, and API pages all render only a 'Connect wallet' prompt
  • No request or response schema provided; callers cannot determine required input fields
  • The KYC verification category may involve regulated data (PII); no compliance or privacy information is available
  • The endpoint path includes a numeric ID (/18) whose meaning is undocumented
