Web page to clean markdown. Converts any URL into LLM-ready markdown plus structured metadata — a keyless alternative to Firecrawl.

Web search plus page reading in one call: answer with sources. Runs a web search, scrapes the top results, and returns the ranked search results together with each page's content as clean LLM-ready markdown, so an agent gets the SERP AND the underlying text without a second round of scrape calls. Per-page fetch errors are reported honestly per URL.

WNBA game schedule for any date — matchups, scores, and game status. Pass a date to find games on a specific day.

Replaces dozens of per-holding calls. From x402stock

Synthesized and fully cited from Bessembinder, Yartseva, Mayer, Alta Fox, LSV, Novy-Marx, and Morgan Stanley. Clean JSON payload. Descriptive research, not advice.

Three textbook baseline forecasts: mean (forecast = average of history), naive (forecast = last value), drift (linear extrapolation from first to last point). Use as a sanity floor - any sophisticated method (SES, Holt, Holt-Winters) should beat the best of these on a backtest, otherwise the extra complexity isn't earning its keep. Returns point forecasts + 95% prediction intervals per Hyndman §3.1.

Extract <title>, <meta description>, OpenGraph/Twitter cards, canonical URL, and JSON-LD blocks from an HTML string. Distinct from /api/meta which fetches a URL - feed this the HTML you already have (from /api/render, /api/extract.body, or your own fetch).

Compute the net present value of a stream of cashflows at a given discount rate. Index 0 is treated as t=0 (today, not discounted); indices 1..n are discounted by (1+rate)^t. Matches Excel's NPV but with the conventional t=0 treatment most finance textbooks use (Excel itself starts discounting at t=1 - see notes). Use for capital-budgeting decisions: positive NPV = creates value at the discount rate; negative = destroys value.
