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/39`. 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 wide range 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 listed 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.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what the KYC verification endpoint actually accepts or returns. The specific endpoint path includes an ID (`/39`), suggesting it may reference a particular verification record, but this is unconfirmed. Users should expect to experiment or contact the provider for integration details.

Quality
The endpoint is live (returns a valid 402 x402 challenge), but there is zero documentation on request/response schemas, no OpenAPI spec, and the docs pages are empty. The specific purpose of the /kyc/verifications/39 path is unclear. This is effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or request/response schema provided; request and response formats are unknown.
- —The endpoint path includes a numeric ID (/39) whose meaning is undocumented.
- —KYC/identity verification is a regulated category — verify the provider's compliance posture before relying on this in production.
- —The platform lists many diverse API categories (AI, finance, infrastructure, KYC) all at the same price, which may indicate placeholder or demo endpoints rather than production services.
