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 85) 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 authorize each call.
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 sits under what appears to be an HR or employee data domain (`/api/v1/employees/85/salary`). However, there is no public documentation describing the request body schema, response fields, or what data is actually returned beyond the generic "Premium API Access" label. The docs, pricing, and API pages on the site are gated behind a wallet-connect flow and yielded no additional content during crawl.
Because there is no OpenAPI spec, no example responses, and no detailed documentation available, the actual data returned by this endpoint is unknown. Callers should treat this as a low-documentation endpoint and test with a small payment first.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a generic label, and the docs pages are empty behind a wallet gate. The purpose of the endpoint (employee salary for ID 85) is narrow and unexplained.
Warnings
- —No OpenAPI or schema documentation available — request body and response format are unknown
- —All documentation pages (docs, pricing, API, README) are gated behind wallet-connect and returned no useful content
- —The endpoint path references a hardcoded employee ID (85); unclear if other IDs are supported or how to discover them
- —The nature and source of the 'salary' data is unspecified — could be mock/demo data
