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 via the x402 payment protocol. The specific resource `/api/v1/kyc/verifications/66` accepts POST requests and charges up to $0.02 per call in USDC on the Base network. Payment is handled inline via the x402 header — no API keys, accounts, or rate limits are required.
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request. However, the specific KYC verification endpoint listed here is not prominently featured on the site's landing page, and no documentation describing its input schema, required fields, or response format was found in the crawl. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content.
Because no input schema or example responses are documented, callers will need to experiment or contact the provider to determine the expected POST body and response structure. The endpoint is confirmed live (returns a valid x402 402 challenge), but the lack of documentation significantly limits usability.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no input/output schema, and no examples. The KYC verification endpoint is not listed on the site's landing page, and all doc pages returned only a wallet-connect prompt. Effectively a stub listing.
Warnings

- —No response schema or example responses available.
- —The /api/v1/kyc/verifications/66 path is not listed among the site's advertised APIs; its purpose and data sources are unclear.
- —Docs, pricing, and API pages returned no useful content beyond a 'Connect wallet' prompt.
- —KYC/identity verification is a regulated category — verify the provider's compliance posture before relying on this in production.
