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/97`. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed (`/api/v1/kyc/verifications/97`) returns a live 402 challenge requesting payment of up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per call. The platform advertises a flat $0.02 per request across all its APIs, with no API keys, no rate limits, and no minimum commitments required. Payment is made via the x402 `exact` scheme to a specified wallet address.
Documentation on the site is extremely thin — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed description of what the KYC verification endpoint accepts or returns. The endpoint path includes a numeric ID (`97`), but it is unclear whether this references a specific verification record or a template. The `outputSchema` in the 402 challenge only specifies that the input method is HTTP POST and that the endpoint is discoverable. Without further documentation, the exact request body format and response structure remain unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is zero documentation on request/response format, no OpenAPI schema, and the docs pages are empty. The KYC verification purpose is inferred solely from the URL path. 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 body format and response structure are completely unknown.
- —The purpose of this endpoint (KYC verification) is inferred only from the URL path; no description confirms this.
- —The numeric ID '97' in the path is unexplained — unclear if it's a resource ID, template, or test fixture.
- —Platform appears to be a generic multi-category API storefront; actual backend service quality and data sources are unverified.
