Retrieve employee SSN data via x402 micropayment on Base (USDC).
What it does
This endpoint at lowpaymentfee.com returns employee Social Security Number (SSN) data for a specific employee (ID 124) 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 confirms the endpoint is live and requires a maximum payment of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per request. The provider's landing page advertises a flat $0.02/request pricing model across all their API endpoints, with no API keys, no rate limits, and instant access.
The broader lowpaymentfee.com platform offers multiple API categories including data/analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all at the same $0.02 per-call price point. However, documentation beyond the landing page is essentially empty (all sub-pages just show "Connect wallet"), so there is no detailed schema, request/response format documentation, or usage guidance available for this specific endpoint.
Capabilities
Use cases
- —Retrieving employee SSN for payroll or HR integrations
- —Agent-driven identity verification workflows requiring SSN data
- —Programmatic access to sensitive employee records with per-call payment
Fit
Best for
- —Agents needing on-demand access to employee PII without API key management
- —Micropayment-based access to sensitive data fields
- —x402-compatible clients on the Base network
Not for
- —Bulk employee data exports (per-call pricing would be inefficient at scale)
- —Users who cannot settle USDC payments on the Base network
- —Production HR systems requiring guaranteed SLAs and documented schemas
Quick start

-H "Content-Type: application/json"Endpoint
Quality
The x402 challenge is live and confirms pricing and payment details, but there is zero documentation for request/response schemas, no OpenAPI spec, and all doc pages are empty. The endpoint deals with highly sensitive PII (SSN) with no visible access controls beyond payment, which raises serious concerns.
Warnings
- —Endpoint serves Social Security Numbers — highly regulated PII (subject to FCRA, state privacy laws, etc.). Use with extreme caution.
- —No documentation exists beyond the landing page; all doc/pricing/API pages return only 'Connect wallet'.
- —No request or response schema is documented — input format and output structure are unknown.
- —No OpenAPI specification or AI plugin manifest available.
- —The endpoint path is hardcoded to employee ID 124; it is unclear whether other employee IDs are supported or how the broader API is structured.
- —No visible authentication or authorization beyond payment — anyone who pays $0.02 may receive SSN data, which is a significant security concern.
