It accepts POST requests and is settled in USDC on the Base network. The x402 challenge confirms the endpoint is live, advertising a max amount 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 x402-gated APIs spanning data/analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per call with no API keys, no rate limits, and no commitments. This particular endpoint is categorized under employee data access. 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 further content.\n\nBecause this endpoint exposes personally identifiable information (SSN), consumers should exercise extreme caution regarding legal compliance (e.g., FCRA, state privacy laws, GDPR) before calling it. The lack of documentation about data provenance, consent, or access controls is a significant concern.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","micropayment"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 employee data","Base USDC API","paid SSN retrieval"],"warnings":["Endpoint exposes Social Security Numbers — highly regulated PII.
