Statistics calculator for a numeric array in one call: count, sum, mean, median, mode, variance and standard deviation honouring ddof (default 1, the sample form; 0 gives the population form) plus always-population *_population fields, min, max, range, the quartiles and interquartile range, skewness, kurtosis, and any requested percentiles. Percentiles use a named interpolation method so the result is reproducible rather than implementation-defined.

Compute the full descriptive-stats panel for an array of numbers in one call: count, sum, mean, median, mode, stddev (sample), variance, min, max, range, q1, q3, IQR. Beats calling 12 separate tools when you already have the array in front of you.

Pearson correlation coefficient between two equal-length numeric series.

Nth percentile of a list of numbers (linear interpolation between closest ranks).

Ordinary least squares simple linear regression (y = slope*x + intercept) with R-squared.

Descriptive statistics for a list of numbers: count, mean, median, sample stdev/variance, min, max.

Pearson correlation coefficient and covariance of two equal-length paired series. Rejected as a clean 400 if the lengths differ or either series has zero variance (correlation undefined).

Full descriptive summary of a numeric sample: count, sum, min/max/range, mean, median, mode(s), variance, standard deviation and the quartiles (q1/q3/iqr). Set sample=true for the sample variance/std…

Evaluate one or more percentiles (0–100) of a numeric sample using linear interpolation between order statistics (the R-7 / Excel PERCENTILE.INC method). 50 is the median, 25/75 the quartiles.

Change watch for status page planetscale: runs the check, compares it with the result from your previous call for the same query (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

Reads invoices, bills and receipts from PDF into structured JSON — vendor, customer, dates, PO, line items, discount, tax, shipping, total, balance due — and checks the arithmetic: quantity × unit price, lines to subtotal, tax rate, total and balance due. The response says exactly which figures don't add up. $0.04 per page (up to 25 pages), quoted per document.

Extracts key keywords from video subtitles for fast topic and content analysis.

Subtitle Timing Repair: Fix SRT and VTT, Words Stay — Repairs the structure of an SRT or WebVTT subtitle file so a video player reads it, without changing a single word and without changing the value of a single time, and answers with the file only, no code fence. Fixes the separator before the milliseconds (a comma in SRT, a dot in VTT), broken arrows, short hours and short millisecond fields, missing or doubled blank lines between cues, cue numbers that skip, repeat or are out of order after …

Compare up to 24 public/synthetic feature summaries: mean differences, reference-standardized shifts and variance ratios. Explicitly flags zero reference variance. Counts and variance convention are declared, not verified; not a distribution test or clinical inference. No raw EEG, participant identifiers or full participant signals.

Compare up to 24 public/synthetic feature summaries: mean differences, reference-standardized shifts and variance ratios. Explicitly flags zero reference variance. Counts and variance convention are declared, not verified; not a distribution test or clinical inference. No raw EEG, participant identifiers or full participant signals. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Summary Fidelity Check — Checks a summary against the source text it was made from and lists the summary sentences the source does not support, each copied word for word, as strict JSON. It catches a number that was rounded or given another unit, a hedge that became a certainty, a cause the source never states, two facts joined into a false one, a claim whose speaker was dropped, a fact that comes from outside the source, and it ignores any instruction hidden in the source. A sentence is judged…

Sunrise, sunset, solar noon, day length, civil/nautical/astronomical twilight and golden hour for Seville today (and tomorrow), computed for the city's coordinates and local timezone. Photography, outdoor scheduling and prayer-time helpers for Seville. $0.01 per call.

Audit your own delimited data against a contract you declare, and get one pass/fail plus the exact row and clause of every breach. Checks types, required values, enums, numeric bounds, lengths, patterns, uniqueness, composite primary keys, null-rate ceilings, header drift and encoding damage in one pass. A pass means the audit was complete and nothing broke, so a file beyond the bounds reports incomplete rather than passing. Nothing is fetched: you supply the rows.

mlpeek (Tanod) named entities: OntoNotes types with offsets (spaCy, English). Use when an agent must find people, organizations, places, dates and amounts in English text.

pdfpeek (Tanod) PDF page extraction: selected pages of a PDF as a new PDF. Use when only certain pages of a PDF are needed as a new, smaller PDF. Add output=url for a 24 h link.

Use when an agent must pull the tables out of a PDF as JSON, CSV or XLSX for analysis. pdfpeek (Tanod) PDF tables: the tables of up to 200 pages of a text PDF read as JSON, CSV or XLSX.

pdfpeek (Tanod) Excel to JSON/CSV: an .xlsx/.xlsm workbook read into sheets of string rows as JSON, or one formula-guarded CSV file per sheet. Use when an agent must read an Excel (.xlsx) workbook into JSON rows or formula-guarded CSV.
