Use cases
What people build on this data
Eight jobs the APIs are actually used for. Each page names the specific capability that makes the job workable (a field, a header, an endpoint, a rate limit), not a generic promise.
Fare alerts
Fire on Google’s own low | typical | high verdict: no price-history database to build.
AI travel agents
Flat JSON tool calls, hosted MCP servers, and a verdict field your agent can reason with.
Rate-parity monitoring
The same room priced from different countries with proxy_country: parity checks from one API.
Fare calendars & heatmaps
Scan a whole month of dates in one burst with rate limits sized for parallel scans.
Metasearch & comparison sites
Live fares with a working buy_link on every result: no booking URL to reconstruct.
Market & fare analysis
Track fare movement against Google’s own price band instead of a homegrown baseline.
Hotel comp-set tracking
Your competitive set by hotel name, on a schedule: no internal property IDs required.
Trip-planning bots
Chatbots that answer with paired round-trips and can honestly say “no flights that day.”
