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 6) 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 payment. The payment timeout is 300 seconds.
The provider (lowpaymentfee.com) hosts a broad catalog of x402-gated endpoints spanning data analytics, AI/ML inference, finance, and utility services, all at the same $0.02 price point. Documentation pages exist but appear to require a wallet connection and contain no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available, so the exact request body format and response structure for this SSN endpoint are unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect gate, and the endpoint serves a single hardcoded employee ID with sensitive PII (SSN). The lack of any documented input/output format and the sensitive data category significantly lower the score.
Warnings
- —Endpoint returns Social Security Number data — this is highly sensitive PII subject to strict regulatory requirements (e.g., FCRA, state privacy laws). Ensure compliance before use.
- —No request body schema or response schema is documented anywhere; integration requires trial and error.
- —Documentation pages (/docs, /pricing, /README) all render only a 'Connect wallet' prompt with no usable content.
- —The endpoint path is hardcoded to employee ID 6; it is unclear whether other employee IDs are supported or how to discover them.
- —No OpenAPI specification or ai-plugin manifest is available.
