    Description, as the server wrote it
    What a Barcelona neighbourhood is actually like, from the city's own published measures: how much street commerce it has, how much road traffic noise reaches residents at night, how steep its streets are, how many households have a child, and how many residents hold a foreign passport. Each figure comes with the city median and the barri's percentile among all 73. Use for questions about whether somewhere is quiet, lively, hilly, family-heavy or international — not for questions about price. None of these explains what a barri costs.
  • rent_trendThe quarterly series of registered rents for one Barcelona neighbourhood or district, and how much it has changed over the window.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    The quarterly series of registered rents for one Barcelona neighbourhood or district, and how much it has changed over the window. Use for questions about whether rents are rising or falling in a specific area. Figures run from 2014 for neighbourhoods and 2000 for districts.

    • The name "find_areas" says "find": a word for reading.
    Description, as the server wrote it

  • get_rentCurrent average rent and sale price for one Barcelona neighbourhood or district, from contracts actually registered with the Catalan government — not listing or asking prices.No findings

    Why it is in this group

    • The name "get_rent" says "get": a word for reading.
    Description, as the server wrote it
    Current average rent and sale price for one Barcelona neighbourhood or district, from contracts actually registered with the Catalan government — not listing or asking prices. Accepts a neighbourhood name, a district name or a URL slug. Returns euros per m² per month, an estimated monthly rent for a reference flat, the sale price per m², gross rental yield where both figures describe the same quarter, and the quarter each figure comes from.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
