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 29). It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, all gated behind the x402 payment protocol. Payment is settled in USDC on the Base network.
The x402 challenge confirms the endpoint is live and accepts POST requests. The maxAmountRequired is 20000 base units of USDC (which uses 6 decimals), equating to $0.02 per request. The provider advertises a flat $0.02/request pricing across all their endpoints, with no API keys, no rate limits, and instant access. No OpenAPI schema, detailed documentation, or example responses were found in the crawl — the docs, pricing, and API pages all returned only a "Connect wallet" prompt with no substantive content.
This endpoint raises significant concerns. It purports to return personally identifiable information (an SSN), which is highly regulated data in the United States. There is no indication of authorization controls, data provenance, compliance with privacy regulations (e.g., FCRA, GLBA, state privacy laws), or whether the data is synthetic/demo versus real. Consumers should exercise extreme caution and verify the legitimacy and legality of this data before use.

Quick start
# Endpoint requires x402 payment header (USDC on Base, $0.02/request)
curl -X POST https://lowpaymentfee.com/api/v1/employees/29/ssn \
-H "X-PAYMENT: <x402_payment_token>" \
-H "Content-Type: application/json"Endpoint
Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no example request/response, and no information about data provenance or compliance. The endpoint claims to serve highly regulated PII (SSN) with no visible authorization or compliance framework, which is a major red flag.
Warnings
- —Endpoint purports to return Social Security Numbers (PII) — highly regulated data in the US. No compliance information (FCRA, GLBA, state privacy laws) is provided.
- —No documentation, OpenAPI schema, or example responses available — all doc pages returned only 'Connect wallet' with no content.
- —Data provenance is unknown — it is unclear whether this is real, synthetic, or demo data.
- —No authorization or access control beyond payment is apparent, raising serious legal and ethical concerns.
- —The specific employee ID (29) is hardcoded in the URL; it is unclear if other IDs are available or what the data source is.
