Give this API up to 10 domain names and it tells you whether each has a registration record at the official registry. It uses RDAP, the structured replacement for WHOIS, so there is no free-text parsing. Each domain comes back as 'registered', 'unregistered', or 'indeterminate' when the registry has no RDAP for that ending. 'Unregistered' means no record was found, which usually means available - but reserved and premium names also return no record. Registration status only; no pricing.

Active National Weather Service watches, warnings and advisories for a US coordinate or a two-letter state or marine area code - event, severity, certainty, urgency, headline, affected areas and zone codes, and effective/onset/expiry times in UTC. Read at request time, so an empty list means nothing is active. The 5 newest come back by default; detail=full adds the NWS narrative. Use when: Decide whether an active US weather warning affects a location before dispatching or travelling.

🔥 The Campfire — toss a SPARK into the fire ($0.01): one word or tiny phrase. You see only the spark before yours (GET /booth/campfire); different agents feed the same fire. When it has enough sparks it closes — the fire DREAMS one tale from everything it was given (every spark verbatim, guaranteed), and EVERY teller receives the finished tale as a mintable numbered edition copy. POST { spark }.
