Pay-per-call employee salary lookup API on Base via x402, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request. It is part of a broader suite of pay-per-call APIs offered by the lowpaymentfee.com platform, which spans data analytics, AI/ML inference, finance, and utility categories. The specific resource `/api/v1/employees/58/salary` returns salary information for employee ID 58 in JSON format.
Payment is handled via the x402 protocol on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). No API keys or rate limits are advertised; access is instant once payment is included in the X-PAYMENT header. The endpoint was confirmed live, returning a proper 402 challenge.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all rendered 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's purpose and response shape must be inferred entirely from the URL path and the generic "Premium API Access" label. This limits confidence in what exactly is returned.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no request/response examples, and all documentation pages are empty beyond a wallet-connect prompt. The endpoint path and description are the only clues to functionality, making this effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All doc/pricing/README pages render only 'Connect wallet' with no technical content
- —The specific resource (employee 58 salary) is very narrow; unclear if other employee IDs are supported
- —No request body schema documented; unclear what POST body (if any) is expected
