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 via the x402 payment protocol. The specific resource `/api/v1/kyc/verifications/6` accepts POST requests and charges up to $0.02 per call in USDC on the Base network. Payment is handled inline via the x402 header — no API keys, accounts, or rate limits are required.
The provider's landing page advertises 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. However, the KYC verifications endpoint is not listed on the homepage, and no documentation, request schema, or response schema is available for it. The docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. Because there is no published input/output schema or usage documentation for this specific endpoint, callers will need to experiment or contact the provider to understand the expected request body and response format.
The endpoint is live: it returns a well-formed x402 challenge (HTTP 402) with USDC payment details on Base (asset 0x8335…2913, 6 decimals, maxAmountRequired=20000 → $0.02). Settlement goes to address 0x1A2B…85F3 with a 300-second timeout.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request/response schemas, no OpenAPI spec, and the KYC endpoint isn't even listed on the provider's homepage. Without knowing what to send or what comes back, this is effectively a stub listing.
Warnings
