Pay-per-call employee salary lookup API on Base via x402, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request, paid per call using the x402 protocol. The specific resource `/api/v1/employees/5/salary` returns salary information for employee ID 5. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an x402 payment header to each request.
The provider, lowpaymentfee.com, hosts a broader catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced uniformly at $0.02 per request. However, the crawled documentation pages (docs, pricing, API reference) returned only a wallet-connect prompt with no substantive content, so details about request/response schemas, accepted parameters, or the structure of the salary data returned are unknown. The endpoint is confirmed live: it returns a proper 402 challenge with x402 version 1 when called without payment.
Because no OpenAPI spec, request schema, or response examples are available, callers will need to experiment or contact the provider for integration details. The output schema in the challenge indicates the endpoint accepts HTTP POST and is discoverable.

Quality
The endpoint is confirmed live with a valid 402 challenge, but there is no OpenAPI spec, no request/response schema, no documentation content (all doc pages just show a wallet-connect prompt), and the endpoint's purpose (employee salary data) is only inferable from the URL path. Effectively a stub listing.
Warnings
- —No OpenAPI or request/response schema available — integration details are unknown
- —All documentation pages (/docs, /pricing, /api, /README) returned only a wallet-connect prompt with no usable content
- —The specific data returned by this endpoint (employee salary) cannot be verified beyond the URL path
- —The endpoint path references a hardcoded employee ID (5); it is unclear whether other IDs are supported or how to parameterize
