Weather & location

Check an IP address against 15 major DNS blacklists (Spamhaus, Barracuda, SORBS, etc.) simultaneously — returns which lists it appears on, a reputation score, and a threat classification so agents can make block/allow decisions instantly.

Transform a source object into a target schema — matches fields by alias and structure deterministically, uses an LLM only for semantic mapping when needed, and supports mapping hints, transforms, and defaults, so agents can reshape data between systems with per-field confidence and a clear report of what mapped and what didn't.

Resolves an IP address or domain to its Autonomous System Number (ASN), network owner, country, and hosting/cloud classification — agents get structured network ownership context plus a trust score to assess infrastructure risk.
