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 115) 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 data, and infrastructure utilities, all priced at $0.02 per request. This particular endpoint sits under the employees resource path and appears to return salary data in JSON format. However, no OpenAPI schema, request body specification, or example response is documented in the crawled material, so the exact input parameters and response shape are unknown.
Because documentation is extremely sparse (the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content), the actual data source, accuracy, and freshness of the salary information cannot be verified. The endpoint is confirmed live — it returns a proper 402 x402 challenge — but callers should be aware that the underlying data quality and schema are unverified.

Quality
The endpoint is confirmed live with a valid 402 x402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no example payloads, and the docs/pricing/README pages are all empty beyond a wallet-connect prompt. The purpose of the data (employee salary for ID 115) is only inferable from the URL path.
Warnings
- —No API documentation available — docs, pricing, and README pages render only 'Connect wallet' with no content.
- —No request body schema or response schema documented; input/output format is unknown.
- —The data source and accuracy of employee salary information cannot be verified.
- —This endpoint path references a specific employee ID (115); it is unclear whether other employee IDs are supported or what the broader resource model looks like.
