## Tools (7)

- `catalog`: The cities covered (with how many prices each has), the beer brands and the serving formats: the slugs the other tools take.
- `cheapest_now`: The cheapest beer prices on right now in the city's time zone, happy hours and timed promos included. Give lat and lng to keep bars within radius_m of a point (distance in metres comes back with each price).
- `get_venue`: A bar's details (kind, bairro, address, location, Instagram, opening hours, attributes) and every beer price it has, cheapest per litre first. The venue slug comes from search_deals or cheapest_now URLs.
- `list_neighbourhoods`: The city's bairros that have beer prices: how many bars and prices each has and its cheapest price per litre, most covered first. The slugs filter search_deals.
- `price_index`: The monthly Índice Cerveja Barata for a city: median, quartiles and minimum price per litre, for the whole city and by format, bairro and brand, with how many prices and bars each cell rests on. Latest month by default; final once the month is closed.
- `price_per_litre`: Convert a Brazilian beer price into reais per litre, the unit Cerveja Barata ranks by. Give the price paid in BRL, the volume of one unit in ml and how many units the price buys (e.g. 5 for a bucket of 5 long necks).
- `search_deals`: Beer prices in a city's bars, cheapest per litre first, each with the bar, the serving, the price, when it applies (happy hours) and when it was last checked. Filter by bairro, brand, format, kind or a maximum price per litre. Open bars only come with kind=open_bar, ranked by package price.
