Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com returns salary information for a specific employee (ID 62) via a POST request. It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML, finance, and utility categories, all settled on the Base network using USDC.
The endpoint charges a maximum of $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is handled inline via the x402 protocol: callers receive a 402 challenge with payment details and must include an X-PAYMENT header to authorize the microtransaction. There are no API keys, no rate limits, and no subscription commitments — you pay per call.
The specific resource `/api/v1/employees/62/salary` is not listed on the provider's landing page among the advertised API categories (Data & Analytics, AI & ML, Finance & Web3, Infrastructure). It appears to be an additional or unlisted endpoint. The response format is application/json, but no detailed schema for the response body is documented. The broader site's docs, pricing, and API pages returned only a "Connect wallet" prompt with no further technical documentation.

Quality
