x402-gated employee salary endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 97) behind an x402 paywall. It is part of a broader platform that offers dozens of pay-per-request API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per call and settled in USDC on the Base network.
The specific resource `/api/v1/employees/97/salary` accepts POST requests and returns JSON. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (contract 0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 exact scheme to wallet 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary response contains or what the POST body should look like. The endpoint is confirmed live (402 challenge returned), but the actual data behind it is unverified and the use case (retrieving a single hardcoded employee's salary) is narrow and unclear in purpose.

Quality
The endpoint is live and returns a valid x402 challenge, but documentation is essentially nonexistent — no request/response schema, no field descriptions, no examples. The endpoint path targets a single hardcoded employee ID with no explanation of the data model. The broader platform lists many endpoints but provides no docs for any of them.
Warnings
- —No API documentation available — docs, pricing, and API pages all show only 'Connect wallet' with no content
- —No OpenAPI or request/response schema provided; request body and response fields are completely unknown
- —Endpoint targets a single hardcoded employee ID (97) — unclear if other IDs are supported or what the data represents
- —The broader platform lists many endpoint categories but none have documented schemas or examples
