Tools (3)

  • search_apis

    Search across 484 endpoints in 59 APIs (cultural, earth, energy-calc, green-path, harmonias, hydrogen, internal, nanobase, nanosnap, natura, platform, sakurahub, science, sim, space, stocks). Returns matching endpoints with method, path, summary, parameters, and a ready-to-run example. Use this to discover available API endpoints before calling execute_api. Results carry a "coverage" field (e.g. ["JP"]) for region-limited APIs; use the "region" filter to narrow.

  • execute_api

    Execute a request against any of the 59 registered APIs. Use search_apis first to find the correct api name and operationId. Requires 'Authorization: Bearer ppn_live_*'.

  • environment_brief

    Environmental brief for one location: fans out to every public geo-aware API (weather, terrain, environment, …) and returns a merged JSON. Partial results come back with an errors[] list. Requires 'Authorization: Bearer ppn_live_*'.
