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/82`. It uses the x402 payment protocol, accepting USDC on the Base network. The endpoint returns a 402 challenge requiring an X-PAYMENT header with payment proof before granting access. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD.
The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-request 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 with no API keys, no rate limits, and no commitments required.
This specific endpoint (`/api/v1/kyc/verifications/82`) is not listed on the site's public catalog, and no documentation was found describing its input schema, required fields, or response format. The `/docs`, `/api`, `/pricing`, and `/README` pages all returned only a "Connect wallet" prompt with no substantive content. Without documentation or example payloads, the exact KYC verification functionality and expected request/response structure remain unknown.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no input/output schema, no examples, and the specific KYC endpoint is not even listed on the provider's public catalog. The docs, API, pricing, and README pages are all empty beyond a wallet connect prompt. This is effectively a stub listing.
