Unified read API over US National Park Service developer.nps.gov. Pick a resource: parks (every NPS unit — historical parks, monuments, seashores, etc.), alerts (closures, dangers, info), campgrounds (NPS-operated campgrounds with reservation links), events (talks, walks, ranger programs), newsreleases (park news), thingstodo (activities by park), visitorcenters. Filter by parkCode (CSV — e.g. "acad,yose,grca"), state, or free-text query. Returns the upstream NPS payload verbatim (rich nested objects with images, addresses, operating hours, etc.).

English dictionary lookup via dictionaryapi.dev (Wiktionary-sourced). Returns full entries with IPA phonetic transcription(s), audio pronunciation URLs, and meanings grouped by part of speech.
