1h/24h realized volatility (stdev of consecutive 1-minute log returns) computed from our own on-chain mid observations for a monitored pair. Actual realized value over the window only -- not annualized, not a forecast. Descriptive statistics only; not investment advice.

Country information API: capital, ISO codes, currencies, languages, calling code, region, area, land borders, and flag emoji for any country by name or 2/3-letter code — one normalized JSON object, answered locally in milliseconds. For form localization, compliance screens, shipping rules, and data-enrichment agents.

Rain nowcast API by coordinates: 15-minute-resolution precipitation for the next 2 hours, for a quick 'will it rain soon' check. Structured JSON for delivery, outdoor-event, and scheduling agents. Radar-based, so coverage is strongest in the US and Europe.

Minute-level precipitation nowcast for the next 2 hours (15-minute steps) for any point on Earth, as structured JSON. Built for agents that need a near-term rain call rather than a daily or hourly forecast. Accuracy depends on regional radar coverage — strongest in the US and Europe, weaker elsewhere.

Health check for a tokenized stock's price oracle on Robinhood Chain: verifies the latest round has a positive answer, valid round accounting, and an update timestamp inside the feed's 24-hour heartbeat window. Returns healthy, stale, or invalid, with every raw round value included. Checks that cannot be verified from official contracts report unsupported — never a silent pass.

npm package info API: the latest published version of any npm package with its publish metadata, license, declared dependencies, deprecation notice if any, and dist details — the pre-install check coding agents should always run. Scoped packages: URL-encode the slash. Cached 1 hour.

On-chain metadata for a Robinhood Chain stock token: verified contract address, ERC-20 name and decimals, total supply in both raw and human units, plus the token's oracle price snapshot. Case-insensitive symbol matching; large integers returned as strings to survive JSON round-trips without precision loss.

Computes the exact molar mass in g/mol for any chemical formula, including nested parentheses like Ca(OH)2 and hydrates like CuSO4·5H2O, with a per-element mass-percentage breakdown. For lab dosing calculations, stoichiometry homework, and pharma formulation agents that can't afford a rounding mistake.

PyPI package inspection API: latest version, summary, license, requires-python, dependency declarations, and yank status for any Python package. The pre-install hygiene check for Python coding agents.

Parses loosely formatted phone number input and returns its E.164 standard representation, country, and line type, with a default-country hint for numbers missing a country code. Built for lead deduplication, SMS delivery systems, and validation steps that reject malformed numbers before they hit a paid messaging API.

OpenGraph and meta tag extraction API: title, canonical URL, favicon, og:*, twitter:*, description, and author for any public page as clean JSON. For link previews, SEO audits, and content cataloging agents.

Turn a city, town, or place name into latitude/longitude, country, admin region, population, elevation, and timezone for up to five matching locations. The step that lets any coordinate-based tool — weather, air quality, sun times — accept a human place name instead of raw numbers. Results cached a full day.

Geocoding API: city or place name to latitude/longitude with country, region, population, and timezone — top matches ranked. The bridge between human place names and every coordinates-based API.

Phone number validation API: is this number valid, what country is it from, and how should it be formatted (E.164, national, international)? Line-type detection included. For lead cleaning, forms, and CRM agents.

Tech news pulse API: the current 30 top-ranked tech stories from the leading hacker community front page — title, outbound article URL, points, author, comment count, and ISO timestamps as normalized JSON. Use for tech trend detection, topic monitoring, newsletter pipelines, and content agents. Cached 3 minutes.

Query the official public holidays for a given country and year, returned with local and English names, nationwide-vs-regional scope, and observing subdivisions. For scheduling agents that need to check whether a date is a holiday before committing to a delivery window or SLA deadline. Cached for a full day.

Country reference data keyed by name or ISO code — currency, capital, languages, calling code, region, area, and neighboring countries — returned as one clean JSON object. Useful for populating currency selectors, tax jurisdiction logic, and data-enrichment pipelines without hardcoding a static country table.

Returns normalized metadata for any npm package, current version, license, dependency list, and whether it's been deprecated, without needing to parse the full, much larger raw registry response. For agents auditing a project's dependency tree or deciding what to install.

Global natural-event tracker: every currently open natural event worldwide — wildfires, severe storms, volcanic activity, sea/lake ice, earthquakes, floods, drought, landslides, and more — with title, category, location, and magnitude data, as normalized JSON. Complements US-only hazard feeds with worldwide coverage. Optional category filter.

Resolve a Bible reference (book, chapter, verse or verse range) to KJV text. Handles common book-name abbreviations case-insensitively; invalid references come back as structured errors.

TLS certificate expiry API: days until any domain's certificate expires, plus issuer, subject, SANs, and validity status — even for already-broken certs. The check monitoring agents run daily.

Knowledge summary API: the lead summary of any English Wikipedia article — title, short description, extract paragraph, thumbnail, and canonical URL — as structured JSON. Titles accept spaces or underscores; missing pages return an unpaid 404. Use for entity enrichment, fact grounding, and research agents. CC BY-SA 4.0 with attribution in every response. Cached 24 hours.

Airport lookup API: resolve any 3-letter IATA or 4-letter ICAO code to the airport's name, city, state, country, coordinates, elevation, and IANA timezone — 29,000+ airports worldwide, answered locally in milliseconds. Unknown codes return an unpaid 404. For travel planning, flight tooling, and logistics agents.

Generates a ready-to-embed QR code image, base64 PNG, from any text or URL input up to 2000 characters, with configurable dimensions and error-correction level. A drop-in way for ticketing systems, packaging, and signage pipelines to produce scannable codes without installing a QR library or maintaining rendering code.
