Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request. The specific resource `/api/v1/employees/24/salary` returns salary information for employee ID 24 in JSON format. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (contract 0x8335…2913) at a cost of $0.02 per request.
The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data & analytics, AI/ML inference (sentiment, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no commitments required.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual data quality and response format behind the paywall cannot be verified from the crawl material alone.

Quality
The endpoint is confirmed live via a valid 402 x402 challenge, but documentation is essentially nonexistent — no OpenAPI spec, no request/response schemas, no example payloads. The docs, pricing, and README pages all show only a wallet-connect prompt. The actual data returned behind the paywall cannot be verified. The description 'Premium API Access' is generic and uninformative.
