Pay-per-call stock data for ITW via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides stock data for the ticker ITW (Illinois Tool Works) via an x402 pay-per-call model. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a maximum cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or subscriptions are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. The specific endpoint `/api/v1/stocks/ITW` falls under the finance category, though the site's landing page lists it under a general "stocks" path rather than the explicitly advertised finance endpoints. Documentation is extremely thin — the /docs, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail.
Because there is no OpenAPI schema, no response examples, and no documentation beyond the landing page listing, the exact shape of the response (fields, data freshness, historical vs. real-time) is unknown. Callers should expect a JSON payload with stock-related data for ITW but should verify the response structure empirically.
