Install the latest stable version from PyPi:

$ pip install --upgrade bravado

Your first Hello World! (or Hello Pet)

Here is a simple example to try from a REPL (like IPython):

from bravado.client import SwaggerClient

client = SwaggerClient.from_url("http://petstore.swagger.io/v2/swagger.json")
pet = client.pet.getPetById(petId=42).response().result

If you were lucky, and pet Id with 42 was present, you will get back a result. It will be a dynamically created instance of bravado.model.Pet with attributes category, etc. You can even try pet.category.id or pet.tags[0].

Sample Response:

Pet(category=Category(id=0L, name=u''), status=u'', name=u'', tags=[Tag(id=0L, name=u'')], photoUrls=[u''], id=2)

If you got a 404, try some other petId.

Lets try a POST call

Here we will demonstrate how bravado hides all the JSON handling from the user, and makes the code more Pythonic.

Pet = client.get_model('Pet')
Category = client.get_model('Category')
pet = Pet(id=42, name="tommy", category=Category(id=24))

Time to get Twisted! (Asynchronous client)

bravado provides an out of the box asynchronous http client with an optional timeout parameter.

Your first Hello World! (or Hello Pet) above can be rewritten to use the asynchronous Fido client like so:

from bravado.client import SwaggerClient
from bravado.fido_client import FidoClient

client = SwaggerClient.from_url(

result = client.pet.getPetById(petId=42).result(timeout=4)


timeout parameter here is the timeout (in seconds) the call will block waiting for the complete response. The default timeout is to wait indefinitely.


To use Fido client you should install bravado with fido extra via pip install bravado[fido].

This is too fancy for me! I want a simple dict response!

bravado has taken care of that as well. Configure the client to not use models.

from bravado.client import SwaggerClient

client = SwaggerClient.from_url(
    config={'use_models': False}

result = client.pet.getPetById(petId=42).result(timeout=4)

result will look something like:

    'category': {
        'id': 0L,
        'name': u''
    'id': 2,
    'name': u'',
    'photoUrls': [u''],
    'status': u'',
    'tags': [
        {'id': 0L, 'name': u''}
