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 (employee ID 60) behind an x402 paywall. The endpoint accepts POST requests and is settled in USDC on the Base network at $0.02 per call (20,000 base units with 6 decimals). No API keys or rate limits are required — payment is handled entirely via the x402 protocol's X-PAYMENT header.
The provider lowpaymentfee.com hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per request. This particular endpoint is part of what appears to be a demo or sample employee data API. The response format is application/json.
Important caveat: This endpoint purports to return Social Security Numbers, which are highly sensitive personally identifiable information (PII). There is no documentation explaining the data source, whether the data is synthetic/demo, or what compliance measures are in place. Consumers should exercise extreme caution and verify the legitimacy and legality of using this endpoint before making any calls.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no request/response schema, no examples, and the endpoint deals with highly sensitive PII (SSNs) with zero compliance or data-source information. The docs, pricing, and API pages on the site are essentially empty (just 'Connect wallet').
Warnings
- —Endpoint returns Social Security Numbers — highly regulated PII. No compliance documentation, data source disclosure, or legal terms are provided.
- —No request or response schema available; impossible to verify what data is actually returned.
- —Documentation pages (/docs, /pricing, /api, /README) are effectively empty — only showing 'Connect wallet'.
- —It is unclear whether the employee data is real or synthetic/demo data.
- —This endpoint is scoped to a single employee ID (60); unclear if other IDs are supported.
