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/29`. 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 listed here accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The platform's landing page confirms a flat $0.02/request pricing model across all its APIs, with no API keys, no rate limits, and no minimum commitments required.
Note that while the platform lists many API categories (analytics, AI, finance, infrastructure), this specific listing is for the KYC verifications endpoint. The exact input schema and response format for this endpoint are not documented in the crawled material — the docs, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. The endpoint is live and returning a valid x402 challenge.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no documentation for the KYC endpoint's input schema, expected request body, or response format. The docs/pricing/README pages are all behind a wallet-connect gate and yielded no content. The endpoint path includes a hardcoded ID (29), and its purpose is only inferable from the URL path.
Warnings
- —No documentation available for this specific KYC endpoint — input schema and response format are unknown.
- —All doc pages (docs, pricing, README, api) returned only 'Connect wallet' with no usable content.
- —The endpoint path includes a specific ID (/verifications/29); it is unclear whether this is a fixed resource or a parameterized path.
- —KYC/identity verification is a regulated category — verify the provider's compliance posture before relying on this in production.
- —The platform description is generic ('Premium API Access') and does not describe KYC-specific functionality.
