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 employee salary information for a specific employee (ID 110) when called via POST. 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. All endpoints on the platform use the x402 payment protocol, settling on the Base network in USDC.
The specific endpoint `/api/v1/employees/110/salary` charges a maximum of 20,000 base units of USDC (0.02 USD) per request, consistent with the provider's flat $0.02/request pricing across all listed APIs. Payment is made via the x402 `exact` scheme, meaning the caller includes a cryptographic payment proof in the `X-PAYMENT` header. No API keys, rate limits, or upfront commitments are required.
Documentation is extremely sparse. The provider's docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary response contains. The endpoint path suggests it returns salary data for a hardcoded employee ID (110), but it is unclear whether the ID is parameterizable or what the response payload looks like.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and no meaningful documentation beyond a wallet-connect prompt. The endpoint path is hardcoded to employee ID 110 with no indication of parameterization. Effectively a stub listing.

- —Docs, pricing, API, and README pages all render only 'Connect wallet' with no technical content
- —Endpoint path is hardcoded to employee ID 110; unclear if other IDs are supported
- —No information on what fields the salary response contains
- —Provider appears to be a demo/showcase site for x402 protocol rather than a production data source
