Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request. The specific resource `/api/v1/employees/127/salary` returns salary information for employee ID 127 in JSON format. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (contract 0x8335…2913) at a cost of $0.02 per request.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. The x402 challenge confirms the endpoint is live and accepting payments.
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 endpoint returns or what input it expects beyond a POST method. The endpoint path suggests it serves a specific employee record (ID 127), but it is unclear whether other employee IDs are available or how the broader employees API is structured.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and all documentation pages returned only a wallet-connect prompt. The specific purpose of the salary endpoint is only inferable from the URL path.
Warnings
- —No OpenAPI or schema documentation available — request and response formats are unknown.
- —All doc/pricing/README pages returned only 'Connect wallet' with no substantive content.
- —The endpoint path is for a single hardcoded employee ID (127); it is unclear if other IDs are supported.
- —The broader platform lists many API categories but none appear to include an 'employees' endpoint, raising questions about whether this is a demo or test resource.
