Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request. The specific resource `/api/v1/employees/63/salary` returns salary information for employee ID 63 in JSON format. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (contract 0x8335…2913).
The endpoint charges a maximum of 0.02 USDC per request (20,000 base units with 6 decimals), consistent with the provider's site-wide flat pricing of $0.02/request. No API keys or account registration are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The provider advertises no rate limits and instant access.
The hosting site lowpaymentfee.com offers a broader catalog of x402-paid APIs spanning data/analytics, AI/ML inference, finance/Web3, and utility endpoints, all at the same $0.02 per-call price point. However, documentation is extremely sparse: the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The actual data source and fidelity of the employee salary information are unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear at $0.02 USDC per call. However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The purpose of the data (employee salary) is vague with no indication of data source or authenticity.
Warnings

- —No request body schema or response schema documented — callers must guess the payload format
- —Data source and authenticity of employee salary information are completely unknown
- —The endpoint path references a specific employee ID (63); generalizability to other IDs is unverified
