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 88) 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. 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 well-formed 402 challenge with x402Version 1.
The provider (lowpaymentfee.com) hosts a broader catalog of x402-gated APIs spanning data/analytics, AI/ML, finance/Web3, and infrastructure utilities — all at the same $0.02 price point. Documentation pages beyond the landing page were essentially empty ("Connect wallet" only), so there is no detailed schema or example response available for this specific SSN endpoint. The nature of the data returned (employee SSN) raises significant regulatory and privacy concerns.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no request/response schema, no examples, and the docs pages are empty stubs. The nature of the data (SSN) raises serious regulatory red flags with no visible compliance information.
Warnings
- —Endpoint serves Social Security Number data — highly regulated PII under US law (FCRA, state privacy laws). No compliance or authorization documentation is visible.
- —No API documentation, request schema, or response schema available — docs pages return only 'Connect wallet'.
- —Endpoint path is hardcoded to employee ID 88; unclear if other employee IDs are supported or how the broader API works.
- —Provider legitimacy is unclear — the domain 'lowpaymentfee.com' hosts a generic catalog of diverse APIs all at $0.02 with no substantive documentation.
- —This may be a demo or test endpoint rather than a production data source; treat returned data with skepticism.
