It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance, crypto, and utility endpoints — all gated behind x402 micropayments settled in USDC on the Base network.\n\nThe endpoint accepts POST requests and returns JSON. Each call costs a maximum of $0.02 (20,000 base units of USDC with 6 decimals) paid via the x402 X-PAYMENT header. There are no API keys, no rate limits, and no subscription commitments — you pay per request. The x402 challenge was successfully captured, confirming the endpoint is live.\n\nDocumentation beyond the landing page is extremely thin: the /docs, /pricing, /api, and /README pages all returned only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available from the crawl. The exact request body format and the shape of the historical stock data response are unknown and must be discovered by experimentation.","tags":[],"capabilities":["stock-history","financial-data","x402-payment","usdc-micropayment","base-network","per-request-pricing","no-api-key"],"categories":["finance","data"],"synonyms":["stock price history","MMM stock data","3M historical prices","equity market data","stock time series","x402 stock API","micropayment stock data"],"warnings":["No OpenAPI or request/response schema available — request body format and response shape are unknown","All documentation pages (/docs, /pricing, /api, /README) returned only 'Connect wallet' with no content","Only the /stocks/MMM/history path was probed; availability of other tickers is unconfirmed","The broader platform lists many endpoint categories but none were individually verified beyond this one"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/MMM/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/MMM/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 (USDC on Base, $0.02/request).
