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 48) via a POST request. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and offers instant access — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. This particular endpoint sits under what appears to be an HR or employee data domain (`/api/v1/employees/{id}/salary`). However, there is no public documentation describing the request body schema, response fields, or what data is actually returned beyond the generic "Premium API Access" label. The docs, pricing, and README pages all render only a wallet-connect prompt with no additional content.
Because there is no OpenAPI spec, no example responses, and no documentation beyond the landing page listing, the actual data returned by this endpoint is unknown. Callers should be prepared for an opaque JSON response and should test with a small payment first.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documentation of request/response schemas, no example payloads, and the docs/pricing/README pages are empty beyond a wallet-connect prompt. The purpose of the endpoint (employee salary data) is only inferable from the URL path.
