Pay-per-call market quote for ITW stock via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides a market quote for the ticker symbol ITW (Illinois Tool Works) via a simple POST request. It is part of a broader platform offering data, analytics, AI, finance, and utility APIs, all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.
The endpoint uses the x402 payment protocol on the Base network, accepting USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with an exact payment scheme. The max amount required is 20,000 base units, which at 6 decimals for USDC equals $0.02 per call. Payment is made via the X-PAYMENT header, and the endpoint returns JSON. The payment timeout is 300 seconds.
The platform hosts a wide catalog of endpoints spanning market data, exchange rates, crypto quotes, gas estimates, AI inference (sentiment, summarization, classification, embeddings), geocoding, validation, and more — all at the same $0.02 price point. Documentation beyond the landing page is sparse; the /docs, /pricing, /api, and /README pages all appear to require a wallet connection and returned no substantive content during crawl.
