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 89) 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), which equals $0.02 given USDC's 6 decimals. This matches the site-wide pricing of $0.02 per request. The provider advertises no API keys, no rate limits, and instant access — payment is the only authentication mechanism. The payment timeout is 300 seconds.
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/request price point. Documentation pages beyond the landing page returned only a "Connect wallet" prompt with no additional technical detail, so the exact response schema and full input parameters are unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response body, and all docs pages return only 'Connect wallet' with no technical content. The endpoint path exposes a hardcoded employee ID (89) with no explanation of how to query other records. The nature of the data (SSN) raises regulatory concerns.
Warnings
- —Endpoint serves personally identifiable information (SSN) — verify compliance with applicable privacy regulations (e.g., CCPA, GLBA, SOC 2) before use.
- —No response schema or request body documentation is available; behavior must be inferred from the endpoint path alone.
- —The endpoint path is hardcoded to employee ID 89; it is unclear whether other employee IDs are supported or how to discover them.
- —All documentation pages beyond the landing page returned only 'Connect wallet' with no usable content.
- —The legitimacy and data source of the SSN data served by this endpoint is unverified.
