The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 \"exact\" scheme, with a maximum cost of $0.02 per request (20,000 base units of USDC with 6 decimals).\n\nThe provider lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint being listed here serves sensitive personally identifiable information (employee SSN). No OpenAPI schema, request body documentation, or response examples are available beyond the x402 challenge metadata. The docs, pricing, and API pages on the site return only a \"Connect wallet\" prompt with no additional technical detail.\n\nBecause this endpoint exposes Social Security Numbers — highly regulated PII under laws such as the Fair Credit Reporting Act, state data breach notification statutes, and GDPR-adjacent frameworks — consumers should exercise extreme caution. There is no indication of access controls, compliance certifications, or data provenance on the provider's site.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","pay-per-request","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","employee record API","SSN retrieval","x402 data API"],"warnings":["This endpoint exposes Social Security Numbers — highly regulated PII.
