It is part of a broader suite of pay-per-request APIs covering finance, analytics, AI, and infrastructure services. The endpoint uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per request.\n\nThe endpoint accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required. The x402 challenge was confirmed live, advertising a maxAmountRequired of 20,000 base units of USDC (0.02 USD given 6 decimals). The provider's landing page lists uniform $0.02 pricing across all endpoints.\n\nDocumentation is extremely sparse. The /docs, /pricing, /api, and /README pages all returned only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The exact request body format and response structure for this stock history endpoint are unknown and must be discovered experimentally.","tags":[],"capabilities":["stock-history","financial-data","x402-payment","usdc-settlement","base-network","per-request-pricing","no-api-key"],"categories":["finance","data"],"synonyms":["stock price history","BA stock data","Boeing historical prices","equity history API","stock market data","x402 stock API","micropayment stock data"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages all return only a wallet connect prompt","No OpenAPI or schema definition; request body format and response fields are unknown","Only the BA (Boeing) ticker is confirmed at this path; availability of other tickers is unverified","Provider site appears to be a generic multi-purpose API platform with uniform pricing; quality and depth of stock data is unverified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/BA/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/BA/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 402 challenge with clear pricing ($0.02 USDC on Base).
