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 SSN (Social Security Number) data for a specific employee record (ID 131) 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 and returning a proper 402 challenge at probe time.
This endpoint is part of a broader platform (lowpaymentfee.com) that offers data/analytics, AI/ML, finance/Web3, and infrastructure utility APIs, all at the same $0.02 per-call price point. Documentation beyond the landing page is essentially empty (pages return only "Connect wallet"), so the request body schema, response format, and the nature of the data returned are unknown. The endpoint path suggests it returns a Social Security Number for employee ID 131, which raises significant regulatory and privacy concerns (PII/sensitive data).

-H "Content-Type: application/json"Endpoint
Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation, no request/response schema, no examples, and the endpoint appears to serve highly sensitive PII (SSN) with no visible compliance or authorization framework. The docs, pricing, API, and README pages all return only 'Connect wallet' with no useful content.
Warnings
- —Endpoint serves Social Security Number data — highly sensitive PII subject to strict regulations (CCPA, GDPR, FCRA, etc.). Verify legal compliance before use.
- —No documentation available: request body schema and response format are completely unknown.
- —Endpoint path is hardcoded to employee ID 131; unclear if other employee IDs are supported or how to parameterize.
- —All secondary pages (docs, api, pricing, README) returned no meaningful content beyond 'Connect wallet'.
- —No OpenAPI spec, no AI plugin manifest, no robots.txt, no agents.txt found.
