Retrieve employee SSN data via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns employee Social Security Number (SSN) data for a specific employee record (employee ID 32) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 "exact" scheme.
The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all their API endpoints, with no API keys, no rate limits, and instant access. The endpoint was live at probe time, returning a valid 402 challenge.
This endpoint is part of a broader platform (lowpaymentfee.com) that offers data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all at the same $0.02 price point. However, this specific endpoint deals with sensitive personally identifiable information (SSN). No documentation beyond the landing page was available; the docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live (valid 402 challenge), but there is no documentation, no request/response schema, no examples, and the endpoint path is hardcoded to a single employee ID (32). The docs pages are empty. The endpoint serves highly sensitive PII (SSN) with no visible access controls beyond payment, which is a significant concern.
Warnings
- —This endpoint returns Social Security Numbers (SSN), which is highly sensitive PII subject to strict regulations (e.g., FCRA, state privacy laws). Use with extreme caution and ensure legal compliance.
- —No documentation, request schema, or response schema is available — behavior must be inferred entirely from the URL path and x402 challenge.
- —The endpoint path is hardcoded to employee ID 32; it is unclear whether other employee IDs are supported or how the broader API is structured.
- —Docs, pricing, API, and README pages all returned only 'Connect wallet' with no substantive content.
- —No OpenAPI spec or AI plugin manifest was found.
