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 16). It is part of a broader suite of x402-protocol APIs offered by the provider, all priced at $0.02 per request and settled in USDC on the Base network. The endpoint uses the x402 payment protocol: callers receive a 402 challenge and must include an X-PAYMENT header with a valid payment proof to access the resource.
The x402 challenge confirms the endpoint is live and accepts POST requests. The maximum amount required is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimal places. No API keys or rate limits are advertised; access is gated purely by per-request micropayment. The response MIME type is application/json.
Important caveat: this endpoint purports to return SSN data, which is highly sensitive personally identifiable information (PII). The provider's documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further detail. There is no OpenAPI schema, no example request/response, and no information about the data source, accuracy, or legal basis for distributing SSN data. Prospective users should exercise extreme caution and verify compliance with applicable privacy and data protection regulations before using this endpoint.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, no documentation beyond a wallet-connect prompt, and the data being sold (SSN) raises serious regulatory red flags with zero provenance information.
Warnings
- —Endpoint claims to return Social Security Number data — highly regulated PII. No information on data source, legal basis, or compliance with privacy laws (e.g., FCRA, GLBA, state privacy statutes).
- —Documentation is effectively nonexistent: docs, pricing, API, and README pages all show only 'Connect wallet' with no further content.
- —No OpenAPI schema or example responses available; actual response format is unknown.
- —Endpoint path is hardcoded to employee ID 16; unclear if other employee IDs are supported or if this is demo/test data.
- —No information about data accuracy, freshness, or whether this is synthetic/test data versus real PII.
