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 (ID 58) 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 USD (USDC uses 6 decimals). 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.
This endpoint is part of a broader platform (lowpaymentfee.com) that offers data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all gated behind x402 micropayments at the same $0.02 price point. Documentation beyond the landing page is essentially empty (all subpages just show "Connect wallet"), so the exact request body schema and response format 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 documentation for request/response schemas, no OpenAPI spec, and all doc pages are empty. The endpoint exposes highly sensitive PII (SSN) with no visible access controls beyond payment, which is a significant concern.
Warnings
- —Endpoint serves Social Security Numbers — highly sensitive PII subject to strict regulatory requirements (e.g., FCRA, state privacy laws). Verify legal compliance before use.
- —No documentation available: all doc/pricing/API pages return only 'Connect wallet' with no actual content.
- —Request body schema and response format are completely unknown — no examples or OpenAPI spec provided.
- —Endpoint is hardcoded to employee ID 58; unclear if other employee IDs are supported or how they are discovered.
- —No visible authentication or authorization beyond payment — anyone who pays $0.02 can retrieve SSN data, raising serious data protection concerns.
