KYC verification endpoint paid per-call via x402 on Base (USDC).
What it does
This endpoint at lowpaymentfee.com provides a KYC (Know Your Customer) verification service accessible via the x402 payment protocol. The specific resource path `/api/v1/kyc/verifications/100` accepts POST requests and charges up to $0.02 per call, settled in USDC on the Base network. No API keys or rate limits are required — callers simply attach an x402 payment header to each request.
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request. However, the KYC verification endpoint is not explicitly listed on the site's landing page, and no documentation was found describing its input schema, required fields, or response format. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content.
Because there is no published documentation for this specific endpoint — no input schema, no example requests or responses, and no description of what "verifications/100" means — callers should treat this as an under-documented service. The x402 challenge is live and well-formed, confirming the endpoint is operational, but the actual behavior behind the paywall is unknown from publicly available information.

Quality
The x402 challenge is live and well-formed, confirming the endpoint exists and accepts payment. However, there is zero documentation on the KYC endpoint's input/output schema, no examples, and the endpoint isn't even listed on the provider's landing page. This is effectively a stub listing.
