## Usage

Supports Python 3.6 or newer. Use the older opencage 1.x releases if you need Python 2.7 support.

Install the module:

```bash
pip install opencage
```

Load the module:

```python
from opencage.geocoder import OpenCageGeocode
```

Create an instance of the geocoder module, passing a valid OpenCage Data Geocoder API key
as a parameter to the geocoder modules's constructor:

```python
key = 'your-api-key-here'
geocoder = OpenCageGeocode(key)
```

Pass a string containing the query or address to be geocoded to the modules's `geocode` method:

```python
query = "82 Clerkenwell Road, London"
result = geocoder.geocode(query)
```

You can add [additional parameters](https://opencagedata.com/api#forward):

```python
result = geocoder.geocode('London', no_annotations=1, language='es')
```

You can use the proximity parameter to provide the geocoder with a hint:

```python
result = geocoder.geocode('London', proximity='42.828576, -81.406643')
print(result[0]['formatted'])
# u'London, ON N6A 3M8, Canada'
```


### Reverse geocoding

Turn a lat/long into an address with the ``reverse_geocode`` method:

```python
results = geocoder.reverse_geocode(51.51024, -0.10303)
```

### Sessions

You can reuse your HTTP connection for multiple requests by
using a `with` block. This can help performance when making
a lot of requests:

```python
queries = ['82 Clerkenwell Road, London', ...]
with OpenCageGeocode(key) as geocoder:
    # Queries reuse the same HTTP connection
    results = [geocoder.geocode(query) for query in queries]
```

### Asycronous requests

You can run requests in parallel with the `geocode_async` and `reverse_geocode_async`
method which have the same parameters and response as their synronous counterparts.
You will need at least Python 3.7 and the `asyncio` and `aiohttp` packages installed.

```python
async with OpenCageGeocode(key) as geocoder:
    results = await geocoder.geocode_async(address)
```

For a more complete example and links to futher tutorials on asycronous IO see
`batch.py` in the `examples` directory.

### Exceptions

If anything goes wrong, then an exception will be raised:
 * ``InvalidInputError`` for non-unicode query strings
 * ``UnknownError`` if there's some problem with the API (bad results, 500 status code, etc)
 * ``RateLimitExceededError`` if you go past your rate limit
