## SDK Documentation
You can learn more about the Transpose SDK and how it works below.
### SDK Classes
The Transpose SDK uses custom classes to represent API responses:
#### Error Classes
<details>
<summary>SDK Error Class Specifications</summary>
The SDK uses the following error classes to represent API errors:
- ``TransposeBadRequest``
- Represents a 400 Bad Request error from the Transpose API.
- ``TransposeRateLimit``
- Represents a 429 Rate Limit error from the Transpose API.
- ``TransposeInvalidAPIKey``
- Represents a 401 Unauthorized error from the Transpose API.
- ``TransposeInternalServerError``
- Represents a 500 Internal Server Error error from the Transpose API.
- ``TransposeResourceNotFound``
- Represents a 404 Not Found error from the Transpose API.
These errors will be raised when the SDK encounters an error from the Transpose API.
</details>
#### Response Classes (**DEPRECATED AS OF v3.1.0**)
<details>
<summary>Response Class Specifications</summary>
The SDK will always return a list of response objects from the Transpose API. For example, calling the ``ens.records_by_date`` endpoint will return a list of ``ENSRecord`` objects.
These response objects can be accessed in the following ways:
- ``ENSRecord[0].ens_name`` will return the first record's ens_name.
- ``ENSRecord[i].ens_name`` retrieves the ens_name from the i-th response
All response objects can also be accessed as a dictionary by calling ``.to_dict()`` on them:
- ``ENSRecord[0].to_dict()`` will return the first record as a dictionary.
- ``ENSRecord[i].to_dict()`` retrieves the i-th record as a dictionary.
</details>
---
## SDK Options
The Transpose SDK can be configured to your liking, allowing you to change the default behavior of the SDK.
### Updating Chain ID
<details>
<summary>
Updating SDK Working Chain ID
</summary>
If you want to change the chain ID of your query, you can do so by setting the `chain_id` or `chain` properties of the `Transpose` object. For example, if you want to query the Ethereum mainnet, you can do so by running the following code:
```python
from transpose import Transpose
api = Transpose(api_key="YOUR_API_KEY", chain_id=1)
```
or
```python
from transpose import Transpose
api = Transpose(api_key="YOUR_API_KEY", chain_id="ethereum")
```
if you wish to change the chain ID of an existing `Transpose` object, you can do so by running the following code:
```python
api.set_chain("ethereum")
```
or
```python
api.set_chain(1)
```
#### Currently supported chains
| Chain ID | Chain Name |
| :------: | :--------: |
| 1 | Ethereum |
| 137 | Polygon |
</details>
### Raw JSON Responses
<details>
<summary>
Opt-in to raw JSON Responses
</summary>
If you wish to receive responses in JSON format, you can set the `json` parameter to `True` when initializing the SDK. This will return all responses as JSON objects.
**Response classes are considered deprecated as of v3.1.0 and will be removed in v4.0.0. JSON responses will become standard in v4.0.0**
```python
from transpose_sdk import Transpose
api = Transpose(api_key="YOUR_API_KEY", json=True)
```
</details>
### Pagination
<details>
<summary>Pagination with the Transpose SDK.</summary>
Transpose endpoints will return a maximum of 500 results in a single query. To return the next page, simply call ``api.next()``. If ``api.next()`` returns ``None``, then there are no more pages.
Here is a standard pagination implementation:
```python
while True:
data = api.next()
# sleep to avoid rate limits
time.sleep(1)
# if there are no more pages, exit loop
if data is None: break
# otherwise, print length of data
else: print(len(data))
```
</details>
### Bulk Requests
<details>
<summary>Bulk requesting data with the Transpose SDK</summary>
Alongside pagination, we also offer a convenience method for iterating over all pages. This method will handle pagination for you, and will return a list of all results.
#### Usage:
```python
api.bulk_request(endpoint_response, requests_per_second, results_to_fetch)
```
| Parameter | Required | Description | Type |
| ------------------- | -------- | ------------------------------------------------------------- | -------- |
| endpoint_response | Yes | The called API function, which returns a list of data models. | ``List`` |
| requests_per_second | No | The number of requests per second to make | ``int`` |
| results_to_fetch | No | The number of results to fetch | ``int`` |
#### Responses
| Code | Title | Model |
| ---- | --------------------- | ------------------------------------------------------------------------------------------------------------ |
| 200 | Success | Data Model |
| 400 | Bad Request | [Error](https://github.com/TransposeData/transpose-python-sdk/blob/main/docs/documentation.md#Error-Classes) |
| 401 | Unauthorized | [Error](https://github.com/TransposeData/transpose-python-sdk/blob/main/docs/documentation.md#Error-Classes) |
| 403 | Forbidden | [Error](https://github.com/TransposeData/transpose-python-sdk/blob/main/docs/documentation.md#Error-Classes) |
| 404 | Not Found | [Error](https://github.com/TransposeData/transpose-python-sdk/blob/main/docs/documentation.md#Error-Classes) |
| 500 | Internal Server Error | [Error](https://github.com/TransposeData/transpose-python-sdk/blob/main/docs/documentation.md#Error-Classes) |
Here is an example of how to use ``bulk_request``:
```python
recent_blocks_since = api.bulk_request(api.block.blocks_by_date(added_after='2022-01-01 00:00:00', limit=500))
print(len(recent_blocks_since))
>>> 500
```
</details>
---
## SDK Extras
The following methods are available as extras to the Transpose SDK.
You can import extras to your project by using:
```python
from transpose.extras import <MODULE>
```
Some extras will require additional dependencies to be installed. If you are missing dependencies, the SDK will throw a `TransposeDependencyError` when you try to import the extra. This error will tell you what dependencies are missing, and give you the exact command to install them:
```shell
transpose.src.util.errors.TransposeDependencyError: Missing Dependencies. You can install these via `pip install plotly kaleido`
```
### Plotting
<details>
<summary>Transpose Plotting Specifications</summary>
The SDK natively includes a plotting library which implements [plotly](https://plot.ly/python/). Using it, you can quickly create plots of data obtained through the Transpose API.
For a plotting example, check out the [demo](https://github.com/TransposeData/transpose-python-sdk/blob/main/demo/plotting.py) file, which will graph the past hour's gas prices in a bar chart.
#### Usage
You'll first need to install the plotting dependencies using:
```shell
pip install plotly kaleido
```
Instantiating a new plot is as simple as importing the ``Plot`` class and instantiating it:
```python
from transpose.extras import Plot
chart = Plot(title="Hourly Gas Prices on Ethereum")
```
This will return an object on which you can call the following methods:
- ``Plot.plotly()``
- Returns the current plot as a plotly object. From there, you can further customize the plot.
- ``Plot.show()``
- Renders the current plot in the browser. This plot is interactive, and can be zoomed and panned.
- ``Plot.render(path, format)``
- Inputs:
- ``path`` -> The path to render the plot to.
- ``format`` -> The format to render the plot as. Can be either ``png``, ``html``, ``jpg``, etc.
- ``Plot.add_data(data, type, shape, smoothing)``
- Inputs:
- ``data`` -> The data to add to the plot. Takes the following format:
```json
{
"x": [], // List of data
"y": [], // List of data
"y_axis": "Gas Price (Gwei)", // OPTIONAL: The name of the y-axis
"x_axis": "Time", // OPTIONAL: The name of the x-axis
}
```
- ``type`` -> OPTIONAL: The method used to render the data to the plot. Can be either ``line`` or ``bar``.
- ``shape`` -> OPTIONAL: The shape of the line. Can be either ``linear``, ``spline``, ``vh``, ``hv``, ``vhv``, or ``hvh``.
- ``smoothing`` -> OPTIONAL: The number of points to smooth the data with.
- For ``line``, this will calculate a moving average of the data with a period of ``smoothing``.
- For ``bar``, this will group and average the data over ``smoothing`` points.
</details>
---
## Making a Request
To get started and make your first request, make a new `Transpose` object:
```python
from transpose import Transpose
api = Transpose('transpose_api_key')
```
From there, you can call endpoints from the `api.nft`, `api.ens`, `api.token`, and `api.block` subclasses.
### Debugging Requests
You can view the raw HTTP requests the SDK is making by setting the `debug` flag to `True` when creating a new `Transpose` object. For example:
```python
from transpose import Transpose
api = Transpose('transpose_api_key', debug=True)
```
## Simple Demo
To show just how powerful our data is, let's get the last ENS domain that expired. All we need is one API call.
```python
from transpose import Transpose
api = Transpose('transpose_api_key')
# get the most recently expired ENS domain
last_expired = api.ens.records_by_date(type='expiration', order='desc', limit=1)
```
This returns a list of [ENS Records](https://github.com/TransposeData/transpose-python-sdk/tree/main/docs/ens.md#ENS-Record-Model), which includes data which you wouldn't be able to easily get from the ENS protocol.
```json

All we need is one API call.\n```python\nfrom transpose import Transpose\n\napi = Transpose('transpose_api_key')\n\n# get the most recently expired ENS domain\nlast_expired = api.ens.records_by_date(type='expiration', order='desc', limit=1)\n```\n\nThis returns a list of [ENS Records](https://github.com/TransposeData/transpose-python-sdk/tree/main/docs/ens.md#ENS-Record-Model), which includes data which you wouldn't be able to easily get from the ENS protocol.\n\n```json\n[\n {\n \"ens_name\":\"game-master-dit-gm.eth\",\n \"ens_node\":\"9BFFC8C1EDE1E51E4BAE137FA37A81CC0379FC08123C4AA00A931D0D983956B7\",\n \"contract_address\":\"0x57f1887a8BF19b14fC0dF6Fd9B2acc9Af147eA85\",\n \"token_id\":75929000750162030430773866845127925090084516346841580577625168871716954805188,\n \"meta_block_number\":407909,\n \"owner\":\"0x2aC92629c4E0E5e4868588f87DC4356606a590b6\",\n \"resolver\":\"0x4976fb03C32e5B8cfe2b6cCB31c09Ba78EBaBa41\",\n \"resolved_address\":\"0x2aC92629c4E0E5e4868588f87DC4356606a590b6\",\n \"registration_timestamp\":\"2022-01-01T05:00:36Z\",\n \"expiration_timestamp\":\"2049-12-31T23:58:12Z\",\n \"grace_period_ends\":\"2050-03-31T23:58:12Z\",\n \"premium_period_ends\":\"2050-04-21T23:58:12Z\",\n \"in_grace_period\":false,\n \"in_premium_period\":false,\n \"is_expired\":false,\n \"last_refreshed\":\"2022-06-01T09:51:23Z\"\n }\n]\n```\n\n## Links\n\n- [SDK Examples](https://github.com/TransposeData/transpose-python-sdk/tree/main/demo)\n- [Transpose Documentation](https://docs.transpose.io)\n- [Official Discord Server](https://discord.gg/AKguqp3U57)\n",
