Pay-per-call employee salary data endpoint on Base via x402 (USDC, $0.02/request).
What it does
This x402-enabled endpoint at lowpaymentfee.com returns salary information for a specific employee (ID 131) in JSON format. It accepts POST requests and settles payments on the Base network using USDC. The price per request is $0.02 (20,000 base units of USDC 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 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, and utility services, all priced at $0.02 per request. However, this specific endpoint (/api/v1/employees/131/salary) is not listed on the provider's public landing page among the advertised API categories, so its exact response schema and data source are unclear. The x402 challenge confirms it is live and accepting payment-gated requests.
Because there is no OpenAPI spec, no documented response schema, and no example responses available, callers should treat this as a lightly documented endpoint. The provider's docs, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical documentation.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no response schema, no example responses, and the endpoint path is not listed among the provider's advertised APIs. Documentation pages are empty beyond a wallet-connect prompt. This is effectively a stub listing.
Warnings
- —No OpenAPI or response schema available — callers cannot know the response structure in advance.
- —This specific endpoint (/api/v1/employees/131/salary) is not listed on the provider's public landing page; its data source and accuracy are unknown.
- —All documentation pages (docs, pricing, README) render only 'Connect wallet' with no technical content.
- —The endpoint appears to serve data for a single hardcoded employee ID (131); generalizability to other IDs is unconfirmed.
