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 information for a specific employee (ID 75) 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 provides instant access — callers simply attach an x402 payment header to each request.
The hosting provider, lowpaymentfee.com, offers 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 and all using the x402 protocol on Base. This particular endpoint (/api/v1/employees/75/salary) appears to serve structured JSON containing salary data for a single employee record. However, no detailed documentation, request/response schema, or example payloads are available from the crawled material — the docs, pricing, and API pages all render only a wallet-connect prompt with no further content.
Because the endpoint is live (returning a proper 402 challenge) but lacks any published documentation about the response format, field definitions, or what input parameters (if any) the POST body accepts, consumers should treat this as a lightly-documented data endpoint. The price is confirmed at $0.02 (maxAmountRequired=20000 in USDC base units with 6 decimals = $0.02).

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no request/response schema, no examples, and the docs pages render only wallet-connect prompts. The endpoint is also scoped to a single hardcoded employee ID, limiting its general utility.
Warnings
- —No API documentation available — docs, pricing, and API pages all render only a wallet-connect prompt with no content.
- —No request body schema or response schema is published; consumers cannot know what fields to send or expect.
- —Endpoint is hardcoded to employee ID 75 — unclear if other employee IDs are supported or how to discover them.
- —The nature and source of the salary data is unknown; could be synthetic/demo data.
