The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys, rate limits, or subscriptions are required — each call is individually paid through the x402 payment header.\n\nThe provider (lowpaymentfee.com) hosts a broad catalog of pay-per-call endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per request. This specific endpoint falls under the finance category and serves stock quote information. However, the crawled documentation pages are essentially empty (showing only \"Connect wallet\"), so there is no detailed schema documentation, example request/response payloads, or field-level descriptions available. The exact fields returned in the stock data response are unknown and must be discovered by making a paid call.\n\nThe endpoint is confirmed live: the probe received a proper HTTP 402 challenge with a valid x402 version 1 payload. The payment timeout is 300 seconds. The endpoint is discoverable and intended for programmatic agent consumption.","tags":[],"capabilities":["stock-quote","x402-payment","per-call-micropayment","base-network","usdc-settlement","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["stock price API","TJX stock data","equity quote","stock market data","micropayment stock API","x402 stock endpoint","pay-per-call finance"],"warnings":["No documentation available — all doc pages return only 'Connect wallet' with no content","Request body schema is unknown; no examples or field descriptions provided","Response schema is completely undocumented; actual stock data fields are unverified","The endpoint is one of many generic-looking endpoints on the same domain; data quality and source are unverified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/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/stocks/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 with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
