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 platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated by the x402 payment protocol on the Base network.
The specific endpoint `/api/v1/employees/77/salary` returns salary information for employee ID 77. Payment is settled in USDC (contract 0x8335…2913 on Base) at a maximum cost of $0.02 per request (20,000 base units with 6 decimals). The x402 challenge was captured live, confirming the endpoint is operational. No API keys or rate limits are required; callers simply attach an X-PAYMENT header with a valid x402 payment proof.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no substantive content. 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 specific employee, but the exact schema and semantics are unknown. The platform advertises uniform $0.02 pricing across all endpoints, no API keys, no rate limits, and instant access.

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 documentation pages are empty stubs. The purpose of the endpoint can only be inferred from the URL path. This is effectively a stub listing.
Warnings
- —No OpenAPI or JSON schema available for request or response bodies
- —All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content
- —Response format and fields are completely unknown — salary data structure is inferred solely from the URL path
- —The endpoint path references a hardcoded employee ID (77); it is unclear if other IDs are supported or how to discover them
