x402-gated employee salary endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 93) behind an x402 paywall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this equals $0.02 per call — consistent with the provider's site-wide flat pricing of $0.02/request. The provider advertises no API keys, no rate limits, and instant access; you simply attach an X-PAYMENT header with a valid x402 payment proof.
The broader lowpaymentfee.com platform hosts a variety of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services, all at the same $0.02/request price point. However, this specific listing covers only the `/api/v1/employees/93/salary` endpoint. Documentation on the site is extremely thin — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawled material. The actual data returned by this endpoint is unknown beyond the stated mimeType of application/json.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the purpose of the data (employee 93's salary) is opaque with no context on what the response contains.
Warnings
- —No API documentation available — docs, pricing, and API pages only show 'Connect wallet'
- —No OpenAPI or JSON schema for request or response bodies
- —The endpoint exposes salary data for a single hardcoded employee ID (93); unclear if other IDs are available
- —Data provenance and accuracy are completely unknown — treat returned data with caution
