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 132) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
The provider site lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. The x402 challenge was successfully captured, confirming the endpoint is live. However, there is no OpenAPI schema, no request/response documentation, and no sample payloads available. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content.
Important caveat: this endpoint purports to return personally identifiable information (an SSN). Consumers should exercise extreme caution and verify the legitimacy and legal compliance of any service claiming to sell SSN data. There is no indication of what authorization or compliance framework governs this data.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request parameters, response schema, or sample data. The endpoint claims to serve SSN data, which is a regulated PII category with no visible compliance information. Docs pages returned no content.
Warnings
- —Endpoint claims to return Social Security Number data — a highly regulated PII category. Verify legal compliance before use.
- —No request or response schema documentation is available; behavior must be discovered empirically.
- —Docs, pricing, and API pages returned only 'Connect wallet' with no substantive content.
- —Legitimacy of the data served is unverified — the provider offers a very broad catalog of unrelated APIs at uniform pricing, which may indicate placeholder or synthetic data.
- —The endpoint is hardcoded to employee ID 132; it is unclear whether other IDs are supported or how to parameterize.
