It accepts POST requests and settles payments in USDC on the Base network. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per request.\n\nThe provider lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. This particular endpoint is specifically scoped to returning SSN information for employee 113. No OpenAPI schema, request body documentation, or response examples were found in the crawl; the docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no additional content.\n\nBecause this endpoint deals with highly sensitive personally identifiable information (SSN), consumers should exercise extreme caution regarding legal compliance (e.g., FCRA, state privacy laws) and data handling obligations before calling this endpoint.
