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 given employee ID (in this case, employee 150). It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, all gated behind the x402 payment protocol. The endpoint accepts POST requests and returns JSON.
Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The maximum amount required per call is 20,000 base units, which at 6 decimals for USDC equals $0.02. No API keys or rate limits are advertised — access is granted purely through the x402 payment header. The x402 challenge specifies a 300-second timeout for payment settlement.
The provider's landing page lists many other endpoints across data/analytics, AI/ML, finance, and utility categories, all at the same $0.02 price point. However, documentation beyond the landing page is essentially empty (pages return only a "Connect wallet" prompt), so there is no detailed schema, field-level documentation, or example responses available for this specific SSN endpoint. The nature of the data returned (SSNs) raises significant regulatory and privacy concerns — consumers should verify the legitimacy and legal compliance of this data source before use.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is zero documentation beyond the landing page — no request/response schema, no examples, no field descriptions. The endpoint deals with highly sensitive PII (SSNs) with no visible compliance or legitimacy information, which is a major red flag.
Warnings
- —Endpoint returns Social Security Numbers — highly regulated PII. Verify legal compliance and data source legitimacy before use.
- —No documentation available: docs, API, pricing, and README pages all return only a 'Connect wallet' prompt with no actual content.
- —No request or response schema is documented; the actual data returned is unknown.
- —No OpenAPI spec or AI plugin manifest found.
- —The employee ID (150) is hardcoded in the URL path — it is unclear whether other employee IDs are supported or how the ID space works.
