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.\n\nThe 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.\n\nBecause 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.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","pay-per-request","no-api-key"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 employee data","Base USDC micropayment API"],"warnings":["Endpoint serves Social Security Numbers — highly sensitive PII.
