# Planetary Computer SDK for Python

Python library for interacting with the Microsoft Planetary Computer.

For general questions or discussions about the Planetary Computer, use the [microsoft/PlanetaryComputer](http://github.com/microsoft/PlanetaryComputer) repository.

## Installation

```python
pip install planetary-computer
```

If you have an API subscription key, you may provide it to the library by using the included configuration CLI:

```bash
planetarycomputer configure
```

Alternatively, a subscription key may be provided by specifying it in the `PC_SDK_SUBSCRIPTION_KEY` environment variable. A subcription key is not required for interacting with the service, however having one in place allows for less restricted rate limiting.


## Development

The following steps may be followed in order to develop locally:

```bash
## Create and activate venv
python3 -m venv env
source env/bin/activate

## Install requirements
python3 -m pip install -r requirements-dev.txt

## Install locally
pip install -e .

## Format code
./scripts/format

## Run tests
./scripts/test
```


## Usage

This library currently assists with signing Azure Blob Storage URLs. The `sign` function operates directly on an HREF string, as well as several [PySTAC](https://github.com/stac-utils/pystac) objects: `Asset`, `Item`, and `ItemCollection`. In addition, the `sign` function accepts a [STAC API Client](https://github.com/stac-utils/pystac-client) `ItemSearch`, which performs a search and returns the resulting `ItemCollection` with all assets signed. The following example demonstrates these use cases:

```python
from pystac import Asset, Item, ItemCollection
from pystac_client import ItemSearch
import planetary_computer as pc


# The sign function may be called directly on the Item
raw_item: Item = ...
item: Item = pc.sign(raw_item)
# Now use the item however you want. All appropriate assets are signed for read access.

# The sign function also works with an Asset
raw_asset: Asset = raw_item.assets['SR_B4']
asset = pc.sign(raw_asset)

# The sign function also works with an HREF
raw_href: str = raw_asset.href
href = pc.sign(raw_href)

# The sign function also works with an ItemCollection
raw_item_collection = ItemCollection([raw_item])
item_collection = pc.sign(raw_item_collection)

# The sign function also accepts an ItemSearch, and signs the resulting ItemCollection
search = ItemSearch(
    url=...,
    bbox=...,
    collections=...,
    limit=...,
    max_items=...,
)
signed_item_collection = pc.sign(search)
```
