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 data for a specific employee (ID 57) via a POST request. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and provides instant access — callers simply attach an x402 payment header to authenticate.
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance & Web3, and infrastructure utilities, all priced at $0.02 per request. This particular endpoint (/api/v1/employees/57/salary) appears to serve structured JSON containing salary information for a given employee record. However, documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further detail on request/response schemas, field definitions, or error handling.
Because there is no OpenAPI spec, no request body schema, and no example responses available, the actual data returned and the required POST body are unknown. The endpoint is confirmed live (returns a valid 402 x402 challenge), but consumers should expect to experiment or contact the provider for integration details.

Quality
The endpoint is confirmed live via a valid 402 x402 challenge, but there is no OpenAPI spec, no request/response schema, no example payloads, and the docs pages are empty beyond a wallet-connect prompt. The purpose (employee salary data) is only inferable from the URL path. This is effectively a stub listing.
Warnings
- —No OpenAPI or request/response schema available — request body and response format are unknown
- —Documentation pages (/docs, /pricing, /api, /README) all render only 'Connect wallet' with no useful content
- —The endpoint path references a hardcoded employee ID (57); it is unclear if other IDs are supported or how to discover them
- —The nature of the 'employee salary' data is unverified — it could be mock/demo data
