Responses include source, license, and coverage-window metadata so callers can distinguish missing data from out-of-window disclosures.

Enables AI agents to answer data-center siting questions by querying a live facility registry, per-metro market intelligence, real-time grid fuel mix and demand, and leasable capacity listings, including a one-call planner that combines these into ranked, cited answers. Results are fetched live per request, keyless, with optional API keys for fuller responses.

Enables AI agents to retrieve daily European underground gas storage levels, LNG terminal inventory and send-out, facility directories, and planned or unplanned outage reports sourced from the AGSI+ and ALSI+ transparency platforms. Storage and LNG level queries require the user's own free API key, while the directory and outage tools work without one.
