Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • bayes_updateBayesian update

    Discrete Bayesian update: given competing hypotheses each with a prior and the likelihood of the observed evidence, return normalised posteriors. Priors are renormalised to sum to 1.

  • calendar_factsCalendar facts lookup

    Description is built at runtime.

  • callCall any tool

    Description is built at runtime.

  • catalogueTool catalogue

    Description is built at runtime.

  • confidence_intervalConfidence interval

    Confidence interval for a mean (t-based; from data, or n/mean/sd) or a proportion (Wilson; successes/n). kind = mean | proportion; confidence default 0.95.

  • coverageCoverage

    Description is built at runtime.

  • de_rates_lookupGerman rates lookup

    Description is built at runtime.

  • descriptive_statsDescriptive statistics

    Summary statistics for a numeric array: mean, median, sd, variance, quartiles, IQR, skewness, min/max.

  • distributionProbability distribution

    Evaluate a probability distribution (normal, t, chi2, binomial, poisson): pdf/pmf and cdf at a value, and/or the quantile at a probability, plus mean & variance. Params per dist: normal {mean,sd}, t {df}, chi2 {df}, binomial {n,p}, poisson {lambda}.

  • domain_provenanceDomain provenance

    Who runs this domain? Live RDAP lookup: registration date and age, registrar, nameservers, status, whether the registrant is redacted, plus a typosquat check (edit-distance / brand-substring) against high-value brands. A very recently registered domain resembling a bank or big brand is a classic phishing signal — but report it as a signal, not a conclusion.

  • eu_safety_gate_recallsEU Safety Gate recalls (stub)

    STUB — not yet live. EU Safety Gate (RAPEX) vehicle alerts are being added; until then this returns covered:false with the official Safety Gate URL and points to fr_recalls_* (RappelConso republishes the Safety Gate automobile alerts that concern France).

  • exam_paper_indexExam past-paper index

    Official past-paper archive links per spec (links to the board's own assessment-resources page — papers are board copyright, so no hosted PDFs).

  • exam_spec_lookupExam spec lookup

    UK exam specification metadata: spec codes, paper structure (count, duration, marks, calculator rules, tiers), topic lists per paper, official spec links.

  • exam_topic_paperExam topic → paper

    Description is built at runtime.

  • fr_recalls_for_modelFrench recalls for a model

    Description is built at runtime.

Show 25 more tools
  • fr_recalls_searchFrench recalls search

    Keyword search across all RappelConso automobile fiches (brand, model text, label, defect description, risks), newest first, optionally since a date. Text is French and lowercase ("airbag", "incendie", "takata", "batterie haute tension"). Use for cross-brand questions ("recent EV battery fire recalls in France").

  • get_factGet a verified fact

    Description is built at runtime.

  • hypothesis_testHypothesis test

    Run a significance test and get the statistic, p-value, and a plain-language interpretation with assumptions. test = one-sample-t {data, mu0}, two-sample-t {data1, data2}, one-proportion-z {successes, n, p0}, two-proportion-z {successes1,n1,successes2,n2}, chi2-gof {observed, expected?}, chi2-independence {table}. Optional tail: two-sided (default) | greater | less; alpha default 0.05.

  • linear_regressionLinear regression

    Simple linear regression of y on x: slope, intercept, r, r², slope std error and p-value, equation.

  • next_holidayNext public holiday

    Description is built at runtime.

  • package_provenancePackage provenance

    Who publishes this package, and is it a typosquat? Live npm or PyPI lookup: first-publish date and age, release count, latest version, maintainers/author, linked repo, plus a typosquat check against popular package names. Use when an agent is about to install or recommend an unfamiliar dependency.

  • policy_rateCentral-bank policy rate

    Current policy rate of one of three central banks, as published on the bank's own page: boe = Bank of England Bank Rate; fed = US Federal Reserve federal funds target range (lower and upper bound); ecb = European Central Bank deposit facility, main refinancing operations and marginal lending facility rates. Returns the figure(s) in % per annum, effectiveFrom, decisionDate and the meeting that set the level, the previous level with its effective date, the latest decision (which may be a hold), the next scheduled decision date, the official source page, the decision press release and verifiedDat…

  • resolve_factFind the key for a fact

    Ranked canonical fact keys for a plain-language question or a guessed key — "NI primary threshold", "ECB deposit rate", "passport renewal fee" — each with label, unit, period and verification date, and the full record of the top match when it is unambiguous. The keys feed `get_fact`. Filter by `namespace` (`uk`, `us`, `de`, `eu`).

  • uk_mot_reliabilityUK MOT reliability

    Real UK MOT failure data for a used car: per-category failure rates (overall and interpolated at a given mileage) and the riskiest components with typical failure mileages, for one model generation. Live proxy to whatbreaks.uk (same operator; aggregated from DfT anonymised MOT results). Use when a user is buying, comparing or maintaining a car sold in the UK. If several generations match, the result lists candidates — retry with year or the exact model name.

  • uk_mot_vehicle_searchUK MOT vehicle search

    Search the 530 UK model generations covered by the MOT dataset by free text (e.g. "focus", "golf"). Use to check coverage or disambiguate a generation before uk_mot_reliability. Live proxy to whatbreaks.uk.
