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.\n\nThe 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.\n\nThe 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.","tags":[],"capabilities":["market-quote","stock-data","x402-payment","usdc-settlement","base-network","pay-per-call","no-api-key"],"categories":["finance","data"],"synonyms":["stock quote API","ITW quote","market data API","Illinois Tool Works quote","equity price lookup","x402 finance API","pay-per-request stock data"],"warnings":["No documentation available — /docs, /pricing, /api, and /README pages all returned only a wallet-connect prompt with no substantive content.","No request or response schema is documented; the shape of the returned market quote is unknown.","The specific data source and freshness/latency of the ITW quote are not disclosed.","The platform lists many endpoint categories but none have visible documentation, raising questions about completeness."],"endpointUrl":"https://lowpaymentfee.com/api/v1/market/quote/ITW","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/market/quote/ITW","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documented request/response format, no example payloads, and all documentation pages returned only a wallet-connect prompt with no content.
