x402-gated employee data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to an employee record (ID 198) behind an x402 paywall. The provider operates a broad catalog of pay-per-request APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all gated via the x402 protocol on the Base network. Each request costs $0.02 in USDC (USD Coin) with no API keys, rate limits, or subscriptions required.
The specific endpoint `/api/v1/employees/198` is not listed on the provider's landing page among the advertised API categories, so it may be a demo, test, or unlisted resource. The x402 challenge confirms it is live and accepts POST requests, returning application/json. The payment is settled on-chain to address 0x1A2B…85F3 using USDC (contract 0x8335…2913) on Base.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact shape of the employee data returned after payment is unknown.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no request/response schema, and the specific employees endpoint is not listed among the provider's advertised APIs. Effectively a stub listing.
