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/13`. It uses the x402 payment protocol, accepting USDC on the Base network. Each call costs $0.02 (20,000 base units of USDC with 6 decimals). The endpoint accepts POST requests and returns JSON.
The broader lowpaymentfee.com platform offers a suite of pay-per-request 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 priced at $0.02 per request with no API keys, no rate limits, and no commitments required — payment is handled entirely through the x402 protocol with USDC on Base.
Note that while the specific KYC verification endpoint is confirmed live (returning a valid 402 challenge), there is no documentation describing the expected request body, response format, or what "verifications/13" specifically refers to. The docs, pricing, and API pages on the site all render only a wallet-connect prompt with no further detail. Treat this endpoint with caution until more documentation becomes available.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is zero documentation on request/response schemas, no OpenAPI spec, and the specific purpose of 'verifications/13' is unexplained. The docs pages are empty wallet-connect prompts. This is effectively a stub listing.
Warnings
- —No documentation available for request body or response schema
- —The path segment '/13' is unexplained — unclear if it refers to a specific verification type or record
- —All documentation pages (docs, pricing, API, README) render only a wallet-connect prompt with no content
- —KYC/identity verification is a regulated category — verify the provider's compliance credentials before use
