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/79`. It uses the x402 payment protocol, settling on the Base network in USDC. The endpoint accepts POST requests and returns JSON responses. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (6 decimals), which equals $0.02 per request.
The broader lowpaymentfee.com platform offers a wide catalog of pay-per-call APIs 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 are uniformly priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments required — payment is handled entirely through the x402 protocol on the Base L2 network.
This specific endpoint appears to be a KYC verification resource. However, the crawled documentation is extremely thin — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further detail. There is no OpenAPI schema, no request/response examples, and no description of what input the KYC verification endpoint expects or what it returns. The endpoint is confirmed live (returns a proper 402 challenge), but the actual functionality and data format remain undocumented.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request format, response schema, or what the KYC verification actually does. Docs pages are empty beyond a wallet-connect prompt. No OpenAPI spec, no examples, and the specific resource path (/verifications/79) is unexplained.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No request or response schema provided; it is unknown what input the KYC endpoint expects or what it returns.
- —The path includes a numeric ID (/79) whose meaning is undocumented — it may be a specific verification type or a placeholder.
- —KYC/identity verification is a regulated category; no compliance certifications or data handling policies are documented.
- —The platform lists many API categories but this specific KYC endpoint is not listed on the homepage catalog.
