It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, crypto, and utility services. Each request costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required.\n\nThe endpoint accepts HTTP POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the payTo address on Base. The x402 challenge was confirmed live, returning a proper 402 response with version 1 of the protocol.\n\nDocumentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema for the TJX quote endpoint. The exact fields returned (e.g., price, volume, timestamp) are unknown and must be discovered by making a paid call.","tags":[],"capabilities":["stock-quote","market-data","x402-payment","usdc-micropayment","base-network","pay-per-request","no-api-key"],"categories":["finance","market-data"],"synonyms":["TJX stock quote","TJX Companies stock price","equity quote API","stock market data","x402 finance API","micropayment stock API","TJX ticker"],"warnings":["No OpenAPI or schema documentation available — response fields for the TJX quote are unknown.","All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no technical content.","The broader lowpaymentfee.com site lists many diverse endpoints (AI, analytics, finance, utils) all at $0.02 — the actual data sources and reliability are unverified.","No example request or response payloads could be obtained without making a paid call."],"endpointUrl":"https://lowpaymentfee.com/api/v1/market/quote/TJX","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/TJX","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base).
