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 resource accessible via the x402 payment protocol. The specific path `/api/v1/kyc/verifications/37` suggests a verification lookup or submission tied to a particular verification record (ID 37). Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
The provider site lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. The x402 challenge was successfully captured (HTTP 402 with valid accepts payload), confirming the endpoint is live. However, there is no OpenAPI schema, no request/response documentation, and no examples available for this specific KYC endpoint. The docs, pricing, and API pages all resolve to a minimal "Connect wallet" prompt with no further detail.
Because the endpoint path references a specific verification ID (37), it is unclear whether this is a generic KYC verification service or a single fixed resource. The lack of documentation makes it impossible to determine the expected POST body, response format, or the nature of the KYC check performed. Treat this listing as a stub until the provider publishes proper documentation.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is zero documentation for this KYC endpoint — no request schema, no response schema, no examples, and no explanation of what verification ID 37 represents. This is effectively a stub listing.
