## What the Agent Does

The agent monitors flight prices on your chosen routes daily using the Aviasales API. You set a target price for each route once — the agent checks every morning and alerts you in Telegram only when the price drops below your threshold or falls more than 15% compared to yesterday. It keeps a price history in memory so you can track trends over time. You never need to manually check flight prices again — the agent waits for the deal and notifies you.
