All currently active severe weather warnings, watches, and advisories for a given US state — event type, severity, urgency, the specific zones affected, and the full alert text — as normalized JSON. Built for logistics rerouting, outdoor-event cancellation logic, and safety-notification agents. US coverage only, refreshed every 5 minutes.

Hiring signals for a French company, derived on demand from France Travail data (snapshot under 24 h, nothing stored): actively-hiring yes/no/unprovable, active-postings count (SIREN-keyed employer page when available, else strict name matching over known locations), top ROME occupation families, contract-type mix, share of postings displaying a pay amount - plus the Egapro gender-equality index and the INSEE workforce bracket. Aggregated signals only, never posting texts or recruiter contacts.

Real-time X synthesis: narrative, sentiment, proven-caller activity

Vocabulary builder serving GRE/SAT-caliber words: each entry has a precise definition, part of speech, natural example sentence, three synonyms, and an advanced/expert difficulty tag. Pull 1-10 random words, filter by difficulty or starting letter. 150 curated entries for tutoring agents, word-of-the-day bots, and test prep.

GRE and SAT vocabulary practice API: draws from 150 curated high-difficulty words — perspicacious, recalcitrant, ephemeral tier — each with definition, usage example, synonyms, and an advanced/expert rating so study agents can ramp difficulty as learners progress.

Descriptive statistics calculator returning mean, median, mode, standard deviation, and full percentile breakdown (p25/p50/p75/p90/p99) for a numeric dataset, plus IQR-flagged outliers. For dataset summarization, benchmarking, and reporting agents that need exact figures, not an LLM's rounded estimate.

Random draws from a curated advanced-English word list, one to ten at a time, each entry carrying part of speech, a precise one-sentence definition, an example sentence, and synonyms. Deterministic dataset with stable entries — the same word always teaches the same meaning.

Astronomy photo of the day API: today's featured space image with title, high-res URL, and the full astronomer-written explanation, as JSON. Use for daily content feeds, newsletters, screensaver bots, and education agents. Cached 6 hours.

Equation solver for linear equations, quadratics with real or complex roots, and 2x2 systems of linear equations, given structured numeric coefficients rather than a text expression to parse. For engineering checks, math tutoring tools, and agents that need guaranteed-exact algebraic solutions.

Physics conversion tool linking light wavelength, frequency, and photon energy — supply any one of nanometers, hertz, joules, or electron-volts and get the others computed exactly from fundamental constants. For optics, photonics, and physics-education agents.

Shape math calculator for area, perimeter, and diagonal length of circles, rectangles, and triangles from plain numeric dimensions — includes Heron's formula for triangles given three sides. Useful for flooring estimates, land-plot sizing, classroom geometry problems, and CAD pre-checks where an exact figure is needed, not an approximation.

Wave physics API: convert between light wavelength (nm), frequency (Hz), and photon energy (joules and eV). Uses exact physical constants.

Percentile and outlier calculator: submit a numeric array and get p25, p50, p75, p90, p99 cutoffs plus IQR-based outlier flags alongside mean, median, and standard deviation. Useful for latency analysis, grading curves, pricing tiers, and any workflow that needs an exact distribution summary.

Periodic table reference returning full physical and chemical data — atomic mass, category, period, group, electron shells, melting and boiling points — for any element by name, symbol, or atomic number. Useful for science education tools, materials databases, and chemistry-adjacent content generation.

List every legal chess move for a position given as FEN, in both SAN (Nf3) and UCI (g1f3) notation, plus turn and check/checkmate/stalemate/draw flags. Pass 'start' for the opening position. For bots playing chess, validating opponents, or teaching the rules.

Returns sunrise, sunset, solar noon, and evening golden-hour timing for any latitude/longitude and date, computed directly with no external lookup delay. Useful for photography scheduling, solar panel estimation, and outdoor-event agents that need precise light timing rather than a rough sunrise/sunset guess.

Mortgage and loan payment calculator: enter principal, annual rate, and term to get the exact monthly payment, total amount paid over the life of the loan, and total interest owed. Built for home-buying estimates, amortization sanity checks, and personal-finance planning agents that need real numbers instead of a rough guess. Not financial advice — just exact arithmetic on the inputs you give it.

Financial calculator API: compound interest (final amount, interest earned, effective annual rate), loan/mortgage payment (monthly payment, total paid, total interest), or ROI — from structured numeric inputs. For fintech, budgeting, and planning agents. Not financial advice; the arithmetic is exact.

Today's featured space image — title, high-resolution image URL, and a full written explanation from an astronomer — refreshed daily. A drop-in content source for newsletters, screensaver bots, and daily-content agents that want a fresh astronomy image with context every day, no image curation required.
