x402-gated employee salary endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 168) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The hosting site lowpaymentfee.com offers a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services, all priced uniformly at $0.02 per call. This specific endpoint falls outside those documented categories and appears to serve structured salary information for a particular employee record. No OpenAPI schema, request body specification, or response example is provided in the available documentation, so the exact input fields and output shape are unknown.
The endpoint is confirmed live: the probe received a proper HTTP 402 challenge with x402 version 1 headers. The payment address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3, and the maximum timeout for payment settlement is 300 seconds.

Quality
The endpoint is confirmed live via a valid 402 challenge, but there is no OpenAPI schema, no documented request/response format, and no explanation of what the salary endpoint actually returns. The crawled docs pages are mostly empty ('Connect wallet'). This is effectively a stub listing.
Warnings
- —No OpenAPI or request/response schema available — input fields and output shape are entirely unknown.
- —This endpoint serves data for a single hardcoded employee ID (168); generalizability is unclear.
- —Documentation pages (/docs, /api, /pricing, /README) returned no meaningful content beyond 'Connect wallet'.
- —The employee salary endpoint is not listed among the site's documented API categories, raising questions about its intended audience and data source.
- —Salary/payroll data may be subject to privacy regulations (e.g., GDPR, CCPA); verify compliance before use.
