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/11/salary` returns salary information for employee ID 11 in JSON format. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (contract 0x8335…2913).
The endpoint charges a maximum of 0.02 USDC per request (20,000 base units with 6 decimals), consistent with the provider's site-wide flat pricing of $0.02/request. No API keys or rate limits are advertised — access is granted purely through the x402 payment header. The provider hosts a broader catalog of endpoints spanning data analytics, AI/ML inference, finance, and utility services, all at the same $0.02 price point.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint is confirmed live (returns a proper 402 challenge), but the actual shape of the salary data returned after payment is unknown.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no OpenAPI spec, no request/response schema, and no examples. The actual data returned is completely unknown, making this effectively a stub listing.
