Capybara: A simple wrapper for multiple tokens of multiple APIs

About

APIs usually require access tokens to limit frequencies of requests.

If you want to request over limitations, you need to generate multiple tokens and roop over them.

Capybara is a simple wrapper for multiple tokens.

# => Kitchen

As a Python module

import capybara

c = capybara.Capybara(config_dir='/path/to/config/', tokens_dir='/path/to/tokens/')

# Amazon
result = c.get(service='amazon', item='B005CSYH5Y')
print result['raw']
print result['title']
print result['category']

# 楽天
result = c.get(service='rakuten', item='urutoragion:10000866')
print result['raw']
print result['title']
print result['url']
print result['category_id']
print result['category']

Setup

anywhere/you/like
   ├── config
   │   ├── amazon_config.json
   │   └── rakuten_config.json
   └── tokens
       ├── amazon_tokens.tsv
       └── rakuten_tokens.tsv

config directory

Set access frequency or other configurations in JSON format for each service.

path/to/config/sample_config.json

{
    "interval": 1000,
    "slow": 1.2
}

Note: Attributes must be in lower cases and "double quoted".

Note

• Actual interval time per token will be [interval]*[slow]
• Thus actual access frequency(per hour) will be [# of tokens]*3600/[interval]*[slow]

tokens directory

List access tokens and other required parameters in TSV format for each service.

See Product Advertising API to get new access tokens.
