x402-gated employee salary endpoint on Base, pay-per-call with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 35) via an x402 payment-gated POST request. It is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and utility services, all settled on the Base network using USDC.
The specific endpoint `/api/v1/employees/35/salary` returns JSON and costs $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is made via the x402 protocol's `exact` scheme: the caller includes an `X-PAYMENT` header with a signed payment to the provider's address on Base. No API keys, rate limits, or subscriptions are required — each call is independently paid.
The broader lowpaymentfee.com platform advertises a uniform $0.02/request pricing across all endpoints. However, the specific endpoint being listed here (`/employees/35/salary`) is not prominently featured on the site's landing page, which focuses on analytics, AI, finance, and utility APIs. The purpose and schema of the salary response are not documented, so the exact fields returned are unknown. The endpoint is live and responding with a valid x402 challenge.

Quality
The endpoint is live and returns a valid x402 challenge, confirming it works. However, there is no documentation for this specific endpoint — no input schema, no output schema, no example responses. The employee salary endpoint is not listed on the provider's landing page, making its purpose and data format unclear. Pricing is inferrable from the challenge but the endpoint's utility is largely opaque.
