Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com returns salary information for a specific employee (ID 186) in JSON format. It is part of a broader suite of pay-per-request APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, and utility categories. The endpoint accepts POST requests and settles payments on the Base network using USDC (USD Coin) via the x402 exact-payment scheme.
The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. This aligns with the provider's uniform $0.02/request pricing advertised across all their endpoints. No API keys or rate limits are required — callers simply attach an x402 payment header to each request. The payment timeout is 300 seconds.
Note that the specific endpoint path (`/api/v1/employees/186/salary`) is not listed on the provider's landing page among their advertised API categories, and no documentation, request schema, or response schema is available. The endpoint is live (returns a proper 402 challenge), but the actual data returned upon successful payment is unknown. There is no OpenAPI spec, no example responses, and the docs/pricing/README pages all render only a "Connect wallet" prompt with no additional content.
