# Get a Brussels to Lisbon fare drop alert

**Use case:** 

Checks one-way Brussels (BRU) to Lisbon (LIS) fares for 3 departure dates starting 45 days ahead, in EUR. Each run stores the cheapest price per date and, from the second run, flags a drop of 5% or more, a new low or a fare at or under 90 EUR, with a ready-to-send alert line. Schedule it daily.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/sillage-data/flight-price-watch.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
