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 behind an x402 paywall. The specific resource `/api/v1/employees/132/salary` returns salary information for employee ID 132 in JSON format. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint charges a maximum of $0.02 per request (20,000 base units of USDC with 6 decimals). It accepts POST requests and requires no API keys or rate limits — access is granted purely through the x402 payment header. The provider's site lists a broad catalog of similarly priced endpoints spanning data analytics, AI/ML inference, finance, and utility services, all at $0.02 per call.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed description of what fields the salary response contains. The endpoint is confirmed live (returns a valid 402 challenge), but the actual data quality and schema behind the paywall are unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing and network details. However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty stubs. The actual data behind the paywall is completely undocumented, making this effectively a stub listing.
Warnings

- —No request or response schema provided; payload structure is unknown
- —The endpoint path suggests employee PII (salary data) which may have regulatory implications
- —Provider site lists many endpoints but none appear to have substantive documentation
