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/67`. 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 advertises a suite of pay-per-request APIs spanning data & analytics, AI & machine learning (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). 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 on the Base L2 network.
The specific KYC verifications endpoint is not listed on the site's main API catalog, and no documentation was found describing its request schema, required fields, or response format. The crawled docs, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. Without input/output schema details or usage examples, integrators will need to experiment or contact the provider to understand the expected request body and response structure.

Quality
The endpoint is live (returns a valid 402 x402 challenge), but there is no documentation, no input/output schema, and the specific KYC endpoint is not even listed on the provider's own landing page. The docs, pricing, and README pages are all empty beyond a wallet-connect prompt. This is effectively a stub listing.
Warnings
- —The /api/v1/kyc/verifications/67 endpoint is not listed in the provider's public API catalog — its purpose and stability are unclear.
- —No request body schema or response schema is documented anywhere; integration requires guesswork.
- —All documentation pages (docs, pricing, README, api) returned only a 'Connect wallet' prompt with no substantive content.
- —The path includes a numeric ID (67) which may refer to a specific verification record rather than a general-purpose endpoint.
