To create one, open Developers at the bottom of Fous Studio, turn on Developer mode, then go to API keys (https://app.fous.com/keys). Change the values in `input` to run the same tool on new data. ```bash curl 'https://api.fous.com/v1/query' \ --fail-with-body --silent --show-error --max-time 180 \ -H "Authorization: Bearer YOUR_API_KEY" \ -H 'Content-Type: application/json' \ --data-raw '{ "api": "@hostelworld", "visibility": "public", "operation": "search_hostels", "version": 1, "input": { "city": "Berlin", "check_in": "2026-10-20", "check_out": "2026-10-22" }, "response": { "format": "json" } }' ``` ```python # Save as fous.py and run with python3 fous.py.

Each method is a typed tool whose arguments are the method’s input. - Server URL: `https://api.fous.com/mcp/tools/hostelworld` - Authorization: `Authorization: Bearer ` **Tools** - `search_hostels`: Search hostels. 1 credit per completed call. Failed calls without a completed billing receipt are free; completed work can remain charged if delivery is interrupted. - `fous_get_run`: the result of a run that was still going, by its `request_id`. Free. Claude Code: ```bash claude mcp add --scope user --transport http fous-hostelworld https://api.fous.com/mcp/tools/hostelworld --header "Authorization: Bearer ${FOUS_API_KEY:?Set FOUS_API_KEY to your Fous API key}" ``` To give the assistant every tool, connect `https://api.fous.com/mcp`: it finds one with `fous_search_tools` and runs it with `fous_run_tool`. Setup for other clients: https://fous.com/llms-full.txt. ## Use cases - Compare nightly dorm-bed and private-room prices - Find properties with a chosen room type - Filter stays by travel dates and guest count - Review property ratings, facilities, and cancellation details - Sort property listings by price ## FAQ ### Can I run it with my own inputs?
