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/93`. It is part of a broader platform that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed (`/api/v1/kyc/verifications/93`) accepts POST requests and returns JSON. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0.02 USD per request, consistent with the platform's uniform $0.02/request pricing). Payment is made via the x402 "exact" scheme to a designated wallet address. No API keys are required; access is granted immediately upon payment.
The platform advertises no rate limits, no minimums, and no commitments. Documentation pages (`/docs`, `/pricing`, `/README`) all resolve but appear to require a wallet connection to view content, so detailed API schemas and request/response formats are not available from the crawl. The specific behavior of the KYC verification endpoint (what input it expects, what verification it performs, what it returns) is not documented in the crawled material.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no documentation on request/response schemas, no OpenAPI spec, and the docs pages require wallet connection to view. The purpose of the specific resource ID '93' is unexplained, and the KYC verification functionality is entirely undocumented in crawled material.
Warnings
- —No API documentation available — all doc pages require wallet connection and returned no content.
- —The specific endpoint path includes a numeric ID (/verifications/93) whose meaning is unclear — it may be a specific verification record rather than a general-purpose endpoint.
- —KYC/identity verification is a regulated category; no information about the provider's compliance certifications, data handling, or jurisdiction is available.
- —Request and response schemas are completely unknown — no OpenAPI spec or examples found.
