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 via the x402 payment protocol. The specific resource `/api/v1/kyc/verifications/22` accepts POST requests and charges up to $0.02 per call in USDC on the Base network. No API keys or rate limits are required — callers simply attach an x402 payment header to each request.
The broader lowpaymentfee.com platform advertises a suite of pay-per-request APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/Web3 data (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with the same x402 payment model on Base.
However, documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical 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 without documentation it is unclear what payload to send or what verification data is returned.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is zero documentation: no OpenAPI schema, no request/response examples, no description of what the KYC verification endpoint accepts or returns. Docs pages are empty. This is effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content.
- —No request or response schema provided; it is unknown what payload the KYC endpoint expects.
- —The specific resource path '/api/v1/kyc/verifications/22' suggests a hardcoded verification ID; unclear if this is a demo or production resource.
- —KYC/identity verification is a regulated category — verify the provider's compliance posture before relying on this for production use.
