Data offered docs-verified: one-way, round-trip and multi-city flight itineraries · fares and price per itinerary · flight legs (airline, flight number, aircraft, departure and arrival airports and times) · carbon emissions per itinerary, compared with the typical route figure · price insights and price history
Coverage llm-inferred: Global
Update frequency llm-inferred: On request: each tool call queries Google Flights live; no refresh schedule documented
Formats docs-verified: JSON · MCP streamable HTTP · MCP stdio (via npm or PyPI launcher)
Access docs-verified: API key required (HasData); free tier of 1,000 credits per month with no card needed; MIT licence

Use cases llm-inferred: Scope 3 business travel emissions estimate for consultancy project reporting · Comparing lowest-emission flight options for staff travel to client sites · Price-checking air travel budgets for international site visits or conferences
Audience llm-inferred: ESG and carbon reporting analysts · sustainability consultants · project managers (travel budgeting)

Constraints llm-inferred: Flight data only; little direct relevance to UK water, civils or environmental consultancy datasets · Each successful call costs 15 credits; the free tier covers about 66 calls per month · Round trips need two calls, the second keyed by departureToken · Airport codes must be IATA codes or kgmids, not city names · A route with no flights on the date returns a successful result with empty arrays · Requires a HasData API key; hosted third-party service adds maintenance and availability risk
