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 (ID 114) 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. The provider advertises no API keys, no rate limits, and instant access — payment is the only authentication mechanism.
This endpoint is part of a broader platform (lowpaymentfee.com) that offers data & analytics, AI/ML inference, finance, and utility APIs, all at the same $0.02/request price point. However, this specific endpoint deals with sensitive personally identifiable information (employee SSN), which raises significant regulatory and ethical concerns. 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 (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation, no example request/response, and the endpoint serves highly sensitive PII (SSN) with no visible compliance or authorization framework. The docs pages are empty stubs.
Warnings
- —This endpoint returns Social Security Numbers (PII/sensitive data). Handling SSNs is subject to strict regulatory requirements (e.g., CCPA, GLBA, state SSN protection laws). Verify legal compliance before use.
- —No documentation, OpenAPI schema, or example responses are available — the actual response format is unknown.
- —The endpoint is hardcoded to employee ID 114; it is unclear whether other employee IDs are supported or what data is actually returned.
- —The provider's docs, pricing, API, and README pages contain no substantive content beyond a wallet-connect prompt.
- —The legitimacy and provenance of the SSN data served by this endpoint cannot be verified from available materials.
