ask_papers

Aggregate questions about the corpus (how many papers disclose a Sharpe ratio / report a backtest / have code, the highest or lowest reported Sharpe, annual return or drawdown, averages, top-N, optionally in an asset class, since a year, net of costs) are answered exactly from the database with the papers linked (engine: sql). Otherwise a retrieval-augmented answer: the question is searched semantically over every paper page, guide and tool, and a language model answers ONLY from the retrieved pages, citing them as markdown links. Returns the answer text plus a sources array of {title, url, kind}. Scores quoted in the answer come from the page text; verify with get_paper. Metered (retrieval + generation): 5 calls per minute and a daily budget; when exhausted, use semantic_search / search_papers.

list_guides

Titles, slugs and one-line descriptions of the ~70 guides on evaluating, reproducing and operationalizing quant research, plus the learning paths (sequenced reading orders). Use get_guide for the text.

{
  "type": "object",

search_papers

Search and filter the 5,000+ scored quant-finance papers. Returns compact records (scores, quadrant, topics, methods, authors, summary, paper_url, page_url) plus the total match count. Combine filters; use min_rigor 7 for credible empirical work; set has_code true for reproducible papers. Reported performance (sharpe, annual_return_pct, max_drawdown_pct, sample_start/end, transaction_costs, out_of_sample) is included when the paper discloses a backtest: filter with has_sharpe / min_sharpe and sort by sharpe or annual_return to answer 'how many papers disclose a Sharpe' or 'highest reported return' questions (use total for counts). Execution-realism flags (tcost_modeled, oos_method, data_resolution, evaluation_type) say whether trading results are net of costs and validated out of sample; empirical_rigor is capped at 6.0 when they are not (empirical_rigor_raw keeps the uncapped score). Follow up with get_paper for the abstract, score rationale and flowchart.

read-only

Argument	Type	Description
q	string	Free-text search over title, abstract, keywords and authors (terms are ANDed).
sort	string	Default: relevance when q is given, otherwise hub_score. sharpe / annual_return / drawdown sort by the paper's reported figures (papers without one last).
type	string	Paper type from the classifier.
asset	string	Asset-class slug: equities, crypto, derivatives, fixed-income, commodities-energy, fx, credit, insurance, macro-multi-asset, esg-climate, private-markets, real-estate.

semantic_search

Meaning-based (vector + keyword hybrid) search over the full text of every paper page, practitioner guide, learning path, calculator and post, via Cloudflare AI Search. Use it for natural-language questions ("does momentum survive transaction costs in crypto?") or when search_papers' exact keyword matching finds nothing. Returns pages with a relevance score, a snippet of the best-matching chunk and, for papers, the scores and labels. No filters beyond kind; for structured filtering use search_papers. Metered upstream: at most 25 results per call, and a daily budget; when it is exhausted the tool says so and search_papers keeps working.

read-only

Argument	Type	Description
q*	string	Natural-language query.
kind	string	Restrict to one page kind.
limit	integer
rewrite	boolean	Let the service rewrite the query for retrieval first (one extra model call).
min_score	number	Drop matches below this relevance score.
