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 148) 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), which equals $0.02 given USDC's 6 decimals. This is consistent with the provider's site-wide pricing of $0.02 per request. No API keys or rate limits are required — access is granted purely through per-request x402 payment. The payment timeout is 300 seconds.
The provider (lowpaymentfee.com) hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services, all at the same $0.02 price point. Documentation beyond the landing page is essentially empty (pages return only "Connect wallet"), so there is no detailed schema for request bodies or response formats for this specific endpoint. The endpoint path suggests it returns PII (an employee's SSN), which raises significant data-sensitivity and regulatory concerns.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is zero documentation on request body format, response schema, or what data is actually returned. The docs, API, pricing, and README pages are all blank beyond a wallet-connect prompt. The endpoint path implies PII (SSN), raising serious regulatory red flags with no compliance information provided.
Warnings
- —Endpoint appears to serve Personally Identifiable Information (SSN) — verify legal and regulatory compliance before use.
- —No documentation exists for request body or response schema; all doc pages return only 'Connect wallet'.
- —The endpoint is hardcoded to employee ID 148; it is unclear whether other employee IDs are supported or if this is a demo.
- —No OpenAPI spec, no examples, no error documentation available.
- —Provider legitimacy and data source are unverifiable from available materials.
