Currency exchange rate API: official daily reference rate for any major fiat pair (USD, EUR, GBP, JPY, ~30 ISO currencies), as JSON. A settlement/normalization reference published each business day — not a live trading feed.

Checks whether an email address is well-formed and whether its domain actually has working mail servers, returning the parsed domain, the sorted list of mail hosts, and a deliverable flag. Doesn't probe the specific mailbox, only the domain's mail setup. Built for lead-list cleaning and signup-form validation agents. Nothing is stored.

Foreign exchange rate API: the official daily reference rate for any major fiat currency pair (~30 ISO 4217 currencies — USD, EUR, GBP, JPY, CHF, AUD...), as structured JSON with the rate date. Published once per business day — ideal for pricing normalization, invoicing, and financial reporting agents; not a live trading feed. Cached 1 hour.

City geocoding API: convert any city or place name to latitude/longitude, with country, admin region, population, elevation, and timezone for the top 5 matches. The bridge from human place names to every coordinates-based API (weather, air quality, sun times). Cached 24 hours.

npm package inspection API: latest version, publish date, license, deprecation status, dependency count, and maintainer count for any npm package. Dependency hygiene for coding agents, cached hourly.

Mole-to-mass-to-molecule-count converter for any chemical formula: supply a mass in grams or an amount in moles and get the full conversion set computed from the compound's exact molar mass. Useful for lab calculations, dosage prep, and chemistry education tools.

single-fact lei lookup. Answers from a bundled CC0 subset of GLEIF Level 1 data, vintage 2026-08-15: 20000 ACTIVE, ISSUED records cut in ascending LEI order from a 1953582-record pool. The range is not dense, so a valid LEI can sort inside it and still be absent; absence here is absence from THIS snapshot, never from the Global LEI System. An unknown or malformed LEI is refused by name, never guessed. The full bound is stated free in the discovery declaration on this challenge.

PDF text extraction API: give it any public PDF URL and get clean layout-preserving text back in one call. Handles digital PDFs up to 25MB. Use it as a PDF parser, PDF-to-text converter, or document ingestion step for RAG and analysis agents. Files are processed in a temp sandbox and deleted immediately.

Volcano hazard API: every US volcano currently at an elevated alert level — alert level (NORMAL/ADVISORY/WATCH/WARNING), aviation color code, observatory, and latest notice time — as normalized JSON. Covers Alaska, Hawaii, the Cascades, Yellowstone, and the Mariana Islands. Use for aviation routing, hazard-monitoring dashboards, and risk-alert agents. Public-domain government data, cached 5 minutes. Returns an empty list when no volcanoes are elevated.

Which chapter of Proverbs to read today, by the classic day-of-month convention, with a highlighted verse of the day and an option to pull the full chapter text.

Today's Proverbs reading: day-of-month picks the chapter (1-31, matching Proverbs' 31 chapters), plus a date-seeded verse highlight from within it. Locally hosted KJV text.

Same-verse-for-everyone daily Bible verse API: date-seeded pick from a curated pool of well-known KJV encouragement passages. Drop it into a devotional bot, morning digest, or Discord daily-message job.

Audio format conversion: takes a public audio or video file URL in formats like mov, wav, ogg, or m4a and returns it as an MP3, ready for playback or downstream processing. Nothing from the source file persists after conversion. Fits into podcast pipelines, voice-note normalization, and any workflow that needs one consistent audio format.

Rolling digest of official space-weather notifications from roughly the past week — geomagnetic storm watches/warnings, solar radiation storms, and other advisories — with message type, issue timestamp, source link, and full advisory text. For grid-operator risk monitoring, aviation/comms planning, and alerting agents that want the human-readable advisory layer, not just raw event data.

The latest official space-weather notifications — coronal mass ejection alerts, geomagnetic storm warnings, solar radiation storms, and weekly summary reports — as structured JSON with type, issue time, and full text for each. Covers roughly the last 7 days by default. For infrastructure-risk agents, science newsletters, and space-weather monitoring dashboards.

HTML to Markdown API: pass a public URL (or raw HTML) and get clean readable markdown back — title, byline, article body with navigation/ads/boilerplate stripped. We honor robots.txt AND Content-Signal (aipref) declarations: a site that disallows agent access returns an unpaid 403, you are never charged. Use for research agents, summarization pipelines, and RAG ingestion.

The classic daily-Proverbs reading: the UTC day of the month selects the matching chapter of Proverbs (the 16th reads Proverbs 16 — the book has exactly 31 chapters), plus a highlighted verse of the day that rotates within the chapter across months. Optional include_chapter flag returns the full chapter text (KJV). Served from locally hosted public-domain scripture. Optional date parameter for any calendar day.

A single King James Version verse chosen deterministically for the day — same result for every caller on that UTC date, from a curated pool of ~375 well-known comfort and encouragement passages.

Worldwide open-event feed filterable to wildfires (or any of 13 official hazard categories: wildfires, severe storms, volcanoes, sea/lake ice, earthquakes, floods, drought, dust/haze, landslides, manmade events, snow, temperature extremes, water color). Each event includes title, category, source link, and the latest geometry (coordinates, magnitude, date). For fire-risk monitoring, logistics rerouting, and global hazard-news agents.

Every US volcano currently under a WATCH, ADVISORY, or WARNING alert level, with its aviation color code and the timestamp of the latest notice.
