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/38`. It uses the x402 payment protocol, accepting USDC on the Base network. The endpoint returns a 402 challenge requiring an X-PAYMENT header with payment proof before granting access. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 per request.
The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this specific listing is for the KYC verifications endpoint. The exact input schema and response format are not documented in the crawled material; the endpoint accepts HTTP POST requests and returns application/json.
Note that while the endpoint is live and responds with a valid x402 challenge, the documentation pages (docs, pricing, API, README) all returned only a "Connect wallet" prompt with no substantive content. The actual request body format and response schema for this KYC verification endpoint are unknown from available sources.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no input/output schema, and no examples available. The KYC verification purpose is inferred solely from the URL path; the actual functionality is unverified. Docs pages are all blank beyond a wallet-connect prompt.
Warnings
- —No documentation available — all doc pages return only 'Connect wallet' with no content.
- —Request body schema for the KYC verification endpoint is completely unknown.
- —Response schema is undocumented; the MIME type is application/json but no fields are specified.
- —The specific endpoint path '/api/v1/kyc/verifications/38' suggests a resource ID (38) which may be specific to a particular verification record rather than a general-purpose endpoint.
- —KYC/identity verification is a regulated category — verify the provider's compliance posture before use in production.
