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 employee salary data for a given employee ID (in this case, employee 100). It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints use the x402 payment protocol on the Base network, accepting USDC with no API keys, no rate limits, and no subscriptions required.
The specific endpoint `/api/v1/employees/100/salary` accepts POST requests and costs $0.02 per call (20,000 base units of USDC on Base, which has 6 decimals). Payment is made via the x402 `exact` scheme to the specified wallet address. The endpoint returns JSON (`application/json` MIME type) and has a maximum payment timeout of 300 seconds.
Documentation on the platform is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation means consumers must discover the response format empirically.

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages return only a wallet-connect prompt. The actual data returned is unknown, making this effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI or JSON schema describing request parameters or response fields
- —Response format must be discovered empirically; no examples provided by the platform
- —The endpoint path suggests demo/sample data (employee ID 100) — unclear if arbitrary employee IDs are supported
