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 (specifically employee ID 181) 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 returns JSON and requires no API keys, rate limits, or upfront commitments — callers simply attach an x402 payment header to each request.
The broader lowpaymentfee.com platform hosts a variety of pay-per-call APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints share the same $0.02/request pricing model and settle on the Base network via x402.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary endpoint accepts or returns. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know what request body to send or what response shape to expect.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it accepts payments on Base in USDC at $0.02/call. However, there is no OpenAPI schema, no request/response examples, and all documentation pages render only 'Connect wallet' with no technical content. The purpose of the specific employee salary endpoint is unclear beyond its URL path.
Warnings
- —No API documentation available — docs, pricing, and API pages all show only 'Connect wallet'
- —No OpenAPI or JSON schema describing request body or response format
- —The endpoint path references a specific employee ID (181); it is unclear whether other IDs are supported or what data is returned
- —The nature and source of the 'salary' data is undocumented — could be mock/demo data
