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 at `/api/v1/kyc/verifications/89`. It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint listed here accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The platform's landing page confirms a flat $0.02/request pricing model across all its APIs, with no API keys, no rate limits, and no minimum commitments required.
Note that while this endpoint is live and responding with a valid x402 challenge, the KYC verification path (`/verifications/89`) suggests it may be tied to a specific verification record or workflow. No detailed documentation, request schema, or response schema was found in the crawl — the docs, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. The actual behavior, required POST body fields, and response format for this KYC endpoint are unknown from the available material.

Quality
The endpoint is live with a valid x402 challenge and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation, no request/response schema, and no explanation of what the KYC verification endpoint actually does or requires. The docs pages returned only wallet-connect prompts. The path includes a hardcoded ID (89) whose meaning is unclear.
