Each request costs $0.02 (20,000 base units of USDC on the Base network, where USDC uses 6 decimals). The endpoint accepts POST requests and returns JSON.\n\nThe provider, lowpaymentfee.com, operates a broad catalog of x402-enabled APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payment is settled on-chain via USDC on Base. The specific endpoint `/api/v1/stocks/AAPL/history` is part of the finance category and is designed to return historical price information for the AAPL ticker.\n\nDocumentation is extremely sparse. The crawled docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the historical data includes (e.g., OHLCV, date ranges, granularity). The endpoint is confirmed live — it returns a valid x402 402 challenge — but the actual data quality and schema are unknown without making a paid request.","tags":[],"capabilities":["stock-history","historical-prices","x402-payment","usdc-base","per-request-billing","no-api-key"],"categories":["finance","data"],"synonyms":["AAPL stock history","Apple stock price API","historical stock data","stock market API","equity price history","AAPL OHLCV"],"warnings":["No documentation available — docs, pricing, and API pages all show only 'Connect wallet' with no content.","No request or response schema provided; field names, date range parameters, and data granularity are unknown.","Only the AAPL ticker path is referenced; it is unclear whether other tickers are supported by changing the URL path.","Data source and freshness of historical stock prices are unverified."],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/AAPL/history","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/AAPL/history","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 x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
