KYC verification endpoint on Base, pay-per-call via x402 with 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 `/api/v1/kyc/verifications/8` accepts POST requests and charges up to $0.02 per call 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-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request. However, the specific KYC verification endpoint's input schema, required POST body fields, and response format are not documented in any crawled material. The docs, pricing, and API pages all resolve to a minimal "Connect wallet" prompt with no further detail.
Because there is no published documentation describing what fields the KYC verification endpoint expects or what it returns, agents should treat this as an exploratory integration. The endpoint is confirmed live (returns a valid x402 402 challenge), but the lack of input/output schema documentation significantly limits usability without trial-and-error.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request/response schemas, required fields, or what the KYC verification actually checks. Docs pages are empty. This is effectively a stub listing.

- —Docs, pricing, and API pages all render only a 'Connect wallet' prompt with no content
