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 87) 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 at probe time, returning a valid 402 challenge.
This endpoint is part of a broader platform (lowpaymentfee.com) that offers data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all at the same $0.02 per-call price point. Documentation beyond the landing page is essentially empty (all sub-pages just show "Connect wallet"), so there is no schema documentation for request body format or response structure. The specific nature of the data returned (whether it is synthetic/demo data or real PII) is not documented.

Quality
The endpoint is live (valid 402 challenge), pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response schema, no examples, and the nature of the data (real PII vs. synthetic demo) is completely undocumented. All doc pages return only 'Connect wallet' with no useful content. The endpoint deals with SSN data which raises serious regulatory and ethical concerns.
Warnings
- —Endpoint purports to return Social Security Number data — this is highly sensitive PII subject to strict regulations (e.g., FCRA, state privacy laws). Verify legal compliance before use.
- —No documentation exists for request body format or response schema — all doc pages are empty.
- —It is unclear whether this returns real, synthetic, or demo data. Do not assume authenticity.
- —Only a single hardcoded employee ID (87) is in the URL; it is unknown whether other IDs are supported.
- —No OpenAPI spec, no AI plugin manifest, no robots.txt, no agents.txt available.
