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 SSN (Social Security Number) data for a specific employee record (employee ID 14) behind an x402 paywall. The endpoint accepts POST requests and is settled in USDC on the Base network at $0.02 per call (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — payment is handled inline via the x402 protocol's X-PAYMENT header.
The provider lowpaymentfee.com hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per request. This particular endpoint is narrowly scoped: it returns sensitive PII (a Social Security Number) for a hardcoded employee ID. No OpenAPI schema, request body documentation, or response examples were found in the crawled material. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no additional content.
Because this endpoint serves highly sensitive personally identifiable information (SSNs), consumers should exercise extreme caution. There is no documentation clarifying whether this is synthetic/demo data or real PII. The legitimacy and legal compliance of this data cannot be verified from the available material.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request format, response schema, or data provenance. The endpoint serves sensitive PII (SSNs) with no explanation of whether data is synthetic or real, raising serious compliance concerns.
Warnings
- —Endpoint serves Social Security Numbers — highly sensitive PII. Legal compliance (GDPR, CCPA, etc.) is unverified.
- —No documentation found: docs, pricing, API, and README pages all returned only 'Connect wallet' with no content.
- —No OpenAPI schema or response examples available — request/response format is entirely unknown.
- —Data provenance unclear: it is unknown whether this is synthetic demo data or real employee PII.
- —Hardcoded employee ID (14) in the URL — unclear if other IDs are supported or how discovery works.
