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 37) 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 suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance, and utility services — all priced at $0.02 per call. However, the specific endpoint under listing here 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 (valid 402 challenge), but there is no OpenAPI schema, no response examples, no request body documentation, and the docs/pricing/README pages are empty stubs. The endpoint serves highly sensitive PII (SSN) with no visible compliance or authorization framework, which is a major red flag.
Warnings
- —Endpoint returns employee SSN — highly sensitive PII. Verify legal compliance (CCPA, GDPR, SOC 2, etc.) before use.
- —No API documentation available; docs, pricing, and README pages return only 'Connect wallet' with no content.
- —No response schema or example responses provided — output format is unknown.
- —Single hardcoded employee ID (37) in the URL; unclear if other employee IDs are supported.
- —No visible authentication, authorization, or access control beyond payment — anyone who pays can retrieve SSN data.
