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/96` 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-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 the crawled material. The docs, pricing, and API pages all resolve to a minimal "Connect wallet" prompt with no further technical detail.
Because no OpenAPI spec, request/response examples, or detailed documentation were found, the exact capabilities and expected payload of this KYC verification endpoint remain unclear. Callers should expect to send a JSON POST body and receive a JSON response, but the specific fields are unknown.

Quality
The endpoint is live (returns a valid 402 x402 challenge), but there is no OpenAPI spec, no documentation of request/response schemas, and no examples. The KYC verification endpoint is not even listed on the site's own landing page catalog. Effectively a stub listing.
Warnings

- —The KYC verification path is not listed among the site's advertised APIs — may be experimental or unlisted
- —Required POST body fields are completely unknown; no request or response examples exist
- —Docs, pricing, and API pages all render only a 'Connect wallet' prompt with no technical content
