Takes one or more district metered areas, each with a flow series and optionally a pressure series, a metered consumption figure and a service connection count, and returns three independent leak indicators per area plus a ranking across all of them. The first is minimum night flow: the lowest flow inside the night window is taken for every night in the record, the median of those nightly minima is reported, and where a connection count is given the legitimate night consumption is subtracted so…

Flexible-load agents buy this endpoint to schedule a contiguous operating window at the lowest average electricity price.

Fits a constant-elasticity demand curve to the price and sales series you supply and returns the elasticity with its standard error, t statistic, two-sided p value and a Student t confidence interval, not a normal one, because at eight observations the difference in interval width is double-digit percent and a too narrow interval is exactly the kind of number a machine reuses unchecked.

Takes a list of candidate intents, each described by attributes, plus whatever is already known, and returns the one attribute worth asking about next. Candidates contradicted by the known values are ruled out first and listed with the attribute that excluded them; a candidate that simply does not declare a known attribute is kept, because silence is not a contradiction.

Takes a message history and a character budget and returns a shortened history together with a full account of what it cost. Four stages run in fixed order: pin protects messages that must survive (roles listed in keep_roles, the last keep_last_n messages, and anything you marked pin), dedupe removes later near-duplicates of an earlier message of the same role using word-overlap similarity, trim shortens unprotected survivors to max_message_chars at the last sentence boundary, and drop removes…

Current levels of the three ECB key interest rates -- main refinancing operations (MRR_FR), deposit facility (DFR) and marginal lending facility (MLFR) -- straight from the official ECB Data Portal (dataflow FM, daily levels). Query: ?last=N (1-60, default 1) to include the N most recent daily observations per rate. Returns latest values plus dated series, in percent per annum; served with a 6h cache.

Resolves an ISBN-10 or ISBN-13 to a normalized bibliographic record from Open Library (Internet Archive): title, authors, publishers, publish date, page count, ISBN identifiers, subjects and cover image URL. Query: ?isbn=9780140328721 (hyphens/spaces tolerated). Unknown ISBNs return 400 (not charged). 7-day cache. Built for catalog management, e-commerce listings and used-book pricing agents.

Offline validation of intermodal container numbers per ISO 6346: owner code, equipment category (U/J/Z), serial and check-digit verification (mod-11 with power-of-2 weights). Catches transcription errors before a booking or B/L is filed. Query: ?container=CSQU3054383. Returns valid flag, parsed parts and the computed check digit. Deterministic, cached 1 year.

Real browser-side adoption signal from the official jsDelivr Stats API: global CDN hit rank, rank within npm, total hits over the period, previous-period comparison and a derived trend (up/down/flat, lower rank = more popular). Query: ?pkg=react&period=week (period: day, week, month, year). Complements npm download counts; cached 6h.

Monthly HICP inflation as annual rate of change (%) from Eurostat dataset prc_hicp_manr, the official primary source. Query: ?geo=EA|FR|DE|EU27_2020 &coicop=CP00 (all items) | CP011 (food) | CP045 (energy) &last_n=12 (1-24 months, default 1). Returns date-sorted observations plus the latest print; 24h cache. Data: Eurostat, CC BY 4.0.

Deterministic Legal Entity Identifier check for regulatory reporting pipelines (EMIR, MiFID II require a valid LEI per counterparty): structure regex and ISO 7064 mod 97-10 checksum over the 20-char code. Query: ?lei=HWUPKR0MPOU8FGXBT394. Returns valid, lou_prefix, entity_part and a failure reason. Filters typos before hitting the GLEIF registry (see /v1/global/lei for the live record). Pure offline, 1y cache.

US weekly jobless claims in one call, live from FRED: initial claims, continuing claims, and 4-week moving average of initial claims, with week-over-week change computed where available — a leading labor-market indicator that drives risk-off and day-trading directional calls. Replaces 3 separate FRED series lookups. Not ticker-specific. $0.01/call.

Top DeFi yield-farming pools by APY across ~15,800 tracked pools, live from DeFiLlama: TVL, base/reward APY split, 7d APY change, impermanent-loss risk, and exposure type, with a $1M TVL floor to filter out illiquid noise. Optionally filter to one chain or stablecoin-only pools. Not ticker-specific. Supports optional limit (default 10, max 25). $0.01/call.

FOMC meeting dates and major US economic release dates (CPI, non-farm payrolls, GDP, PCE, retail sales) in one call, each with a days-until countdown, between 'from' and 'to' -- the market-wide catalysts that move every ticker at once. FOMC dates from the Fed's official calendar; release dates live from FRED, and a temporarily-unavailable release is reported explicitly, not silently dropped. Not ticker-specific. $0.01/call.

Turns SenML (JSON or CBOR) and LwM2M TLV into one record shape: resolved name, unit, absolute timestamp, typed value. Optionally puts every series on a shared time axis with a chosen interval and fill rule (last value, bucket mean, linear). Works only on the payload you pass: no device is contacted, nothing is stored, the same request returns the same bytes. TLV carries no type on the wire; unmapped resource ids come back as opaque base64 with a warning instead of a guess.

Builds the cohort table from the events you pass: users grouped by the period of their first event, counted again in each following period. Returns the table per cohort, a retention curve across all cohorts, and, where events carry a value, cumulative value and value per user. The curve counts only cohorts old enough for a given period, so a young cohort is not scored as churn. Day, week and month are real calendar periods. Nothing is fetched, nothing is stored.

Takes a machine definition, the current state, one event and an optional context, and computes a single step. Transitions may carry a guard, which is a declared comparison — field, operator, value — and never an expression: the field is a dotted path into context or payload, so a machine handed in by a stranger cannot execute anything on this server.

Reads one conversion experiment two ways at once. Frequentist: two-proportion test, p value, confidence interval on the absolute lift, and the sample size the requested minimum detectable effect needs at the requested power. Bayesian: Beta-Binomial posteriors, probability the variant is better, expected loss either way, credible intervals - closed form, not sampled, so the numbers repeat exactly. looks_taken carries the adjusted threshold and the rate you actually ran at.

Runs three detectors over one series and reports what each saw: a robust z score on median and median absolute deviation, a robust seasonal-trend decomposition with a z score on the residual, and an isolation forest over value and step-to-previous. Every score is returned per point, so callers set their own threshold instead of trusting a verdict. The forest draws from a fixed seed: same request, same result. Under three full cycles the seasonal figure is marked as not robust.

Takes a list of returns with the figures your own systems already hold and returns one decision per return, with the arithmetic that produced it. Four routes are valued: reselling as is, at the resale value weighted by the probability that it actually sells and less the restocking cost; repairing and reselling, at the refurbished value weighted by the repair success probability plus the salvage value on the failure branch, less the repair cost, which is incurred either way; recovering value…

Checks a name against the Specially Designated Nationals and Blocked Persons List published by the US Treasury Office of Foreign Assets Control. Returns each hit with the OFAC record number, the record type (individual, entity, vessel, aircraft), every sanctions programme the record is listed under, the aliases OFAC publishes together with their a.k.a./f.k.a./n.k.a.

Takes an inventory — the controller, and one entry per processing activity with its purposes, the stated legal basis, the categories of data subjects and of personal data, the categories of recipients, any third-country transfers, the erasure periods and the security measures — and returns it laid out as a draft record of processing activities under Article 30(1) GDPR.

Computes a transparent planning estimate for space-heating demand. The method is not DIN, VDI, GEG or PHPP and must not be used as regulatory proof. It combines transmission heat loss from each envelope component, ventilation heat loss from heated volume and air changes, monthly heating degree days from the nearest DWD 1991-2020 temperature-normal station, stated internal gains and optional domestic hot water.
