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/64`. It uses the x402 payment protocol, accepting USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to access the resource.
The broader lowpaymentfee.com platform hosts a variety of pay-per-call API endpoints spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance and crypto data (price feeds, exchange rates, gas estimates), and infrastructure utilities (geocoding, validation, conversion). All endpoints share the same $0.02/request pricing model and settle on the Base network via USDC.
Documentation for this specific KYC verification endpoint is sparse. The crawled docs, pricing, and API pages all returned only a "Connect wallet" prompt with no additional technical detail. The input schema indicates an HTTP POST method, but no request body schema or response schema is documented. The endpoint path includes an ID segment (`/64`), suggesting it may retrieve or trigger verification for a specific resource or verification record, but this is not confirmed by available documentation.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02/request in USDC on Base). However, there is no request body schema, no response schema, no documentation beyond a wallet-connect prompt, and the specific purpose of the /kyc/verifications/64 path is undocumented. This is effectively a stub listing.
Warnings
- —No request body schema or response schema documented for this endpoint
- —All documentation pages (docs, pricing, API, README) returned only 'Connect wallet' with no technical content
- —The path segment '/64' is unexplained — unclear if this is a fixed resource ID or a parameterized path
- —KYC/identity verification is a regulated category — verify compliance requirements before use
- —The endpoint title 'Premium API Access' is generic and does not describe the KYC function
