Batch API Access
|
|
----------------
|
|
|
|
If you'd like to use our batch api interface, please check out the [pricing page](https://indico.io/pricing) on our website to find the right plan for you.
|
|
|
|
```
|
|
>>> from indicoio import batch_sentiment
|
|
>>> batch_sentiment(['Text to analyze', 'More text'], auth=("example@example.com", "********"))
|
|
```
|
|
|
|
Authentication credentials can also be set as the environment variables `$INDICO_USERNAME` and `$INDICO_PASSWORD` or as `username` and `password` in the indicorc file.
|
|
|
|
Private cloud API Access
|
|
------------------------
|
|
|
|
If you're looking to use indico's API for high throughput applications, please check out the [pricing page](https://indico.io/pricing) on our website to find the right plan for you.
|
|
|
|
```
|
|
>>> from indicoio import sentiment
|
|
>>> sentiment("Text to analyze", cloud="example", auth=("example@example.com", "********"))
|
|
```
|
|
|
|
The `cloud` parameter redirects API calls to your private cloud hosted at `[cloud].indico.domains`
|
|
|
|
Private cloud subdomains can also be set as the environment variable `$INDICO_CLOUD` or as `cloud` in the indicorc file.
|
|
|
|
Configuration
|
|
------------------------
|
|
|
|
Indicoio-python will search ./.indicorc and $HOME/.indicorc for the optional configuration file. Values in the local configuration file (./.indicorc) take precedence over those found in a global configuration file ($HOME/.indicorc). The indicorc file can be used to set an authentication username and password or a private cloud subdomain, so these arguments don't need to be specified for every api call. All sections are optional.
|
|
|
|
Here is an example of a valid indicorc file:
|
|
|
|
|
|
```
|
|
[auth]
|
|
username = test@example.com
|
|
password = secret
|
|
|
|
[private_cloud]
|
|
cloud = example
|
|
```
|
|
|
|
Environment variables take precedence over any configuration found in the indicorc file.
|
|
The following environment variables are valid:
|
|
|
|
```
|
|
$INDICO_USERNAME
|
|
$INDICO_PASSWORD
|
|
$INDICO_CLOUD
|
|
```
|
|
|
|
Finally, any values explicitly passed in to an api call will override configuration options set in the indicorc file or in an environment variable.
