Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request. The specific resource `/api/v1/employees/65/salary` returns salary information for employee ID 65 in JSON format. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (contract 0x8335…2913) with no API keys, accounts, or rate limits required.
The endpoint charges a maximum of 0.02 USDC per request (20,000 base units with 6 decimals), consistent with the provider's flat $0.02/request pricing across all their API offerings. The provider, lowpaymentfee.com, hosts a broader catalog of endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all at the same $0.02 per-call price point.
Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed description of what fields the salary response contains. The endpoint is confirmed live (402 challenge captured), but the actual data returned and its accuracy are unknown.
