First steps

Log in at opper and create your own API key in the top right menu. Each api key is associated with a project, you will have all calls, functions, indexes and traces associated with this project. There is a default project for each organization but it is recommended to create a new project to better being able to separate the different applications and environments.

For many examples and guides of how to use our sdks check out our examples folder examples

Example

from opperai import Opper
# Our SDK supports Pydantic to provide structured output
from pydantic import BaseModel
import os

# Define the output structure
class RoomDescription(BaseModel):
    room_count: int
    view: str
    bed_size: str
    hotel_name: str

def main():
    opper = Opper(http_bearer=os.getenv("OPPER_API_KEY"))

    # Complete a task
    completion = opper.call(
        name="extractRoom",
        instructions="Extract details about the room from the provided text",
        input="The Grand Hotel offers a luxurious suite with 3 spacious rooms, each providing a breathtaking view of the ocean. The suite includes a king-sized bed, an en-suite bathroom, and a private balcony for an unforgettable stay.",
        output_schema=RoomDescription,
    )

    print(completion.json_payload)
    #{'room_count': 3, 'view': 'ocean', 'bed_size': 'king-sized', 'hotel_name': 'The Grand Hotel'}

main()

The same SDK client can also be used to make asychronous requests by importing asyncio. Just add _async to the call

Async example
# Asynchronous Example
import asyncio
import os
from opperai import Opper
from pydantic import BaseModel

# Define the output structure
class RoomDescription(BaseModel):
    room_count: int
    view: str
    bed_size: str
    hotel_name: str

async def main():
    opper = Opper(http_bearer=os.getenv("OPPER_API_KEY"))

    # Complete a task asynchronously
    completion = await opper.call_async(
        name="extractRoom",
        instructions="Extract details about the room from the provided text",
        input="The Grand Hotel offers a luxurious suite with 3 spacious rooms, each providing a breathtaking view of the ocean. The suite includes a king-sized bed, an en-suite bathroom, and a private balcony for an unforgettable stay.",
        output_schema=RoomDescription,
    )

    print(completion.json_payload)
    # {'room_count': 3, 'view': 'ocean', 'bed_size': 'king-sized', 'hotel_name': 'The Grand Hotel'}

# Run the async main function
asyncio.run(main())

Authentication

See our authenthication docs auth

This SDK supports the following security scheme globally:

Name Type Scheme Environment Variable
http_bearer http HTTP Bearer OPPER_HTTP_BEARER

To authenticate with the API the http_bearer parameter must be set when initializing the SDK client instance. For example:

from opperai import Opper
import os

http_bearer="YOUR_API_KEY"
opper = Opper(http_bearer)

Available Resources and Operations

Available methods
  • update - Update Dataset Entry
  • list - List Function Revisions
  • list - List Traces
  • get - Get Trace

Server-sent event streaming

Server-sent events are used to stream content from certain operations. These operations will expose the stream as Generator that can be consumed using a simple for loop. The loop will terminate when the server no longer has any events to send and closes the underlying connection.

from opperai import Opper
import os


opper = Opper(http_bearer=os.getenv("OPPER_API_KEY"))

def stream_call():
    """Print the assistant’s answer as it streams back from Opper."""
    outer = opper.stream(
        name="python/sdk/bare-minimum-with-stream",
        instructions="answer the following question",
        input="what are some uses of 42",
    )

    # Pull out the inner EventStream object in one line.
    stream = next(value for key, value in outer if key == "result")

    # Read each Server-Sent Event and emit the delta text.
    for event in stream:  # event: ServerSentEvent
        delta = getattr(event.data, "delta", None)
        if delta:  # skip keep-alives, etc.
            print(delta, end="", flush=True)

The stream is also a Context Manager and can be used with the with statement and will close the underlying connection when the context is exited.

Context Manager Stream Example
from opperai import Opper
import os


with Opper(
    http_bearer=os.getenv("OPPER_HTTP_BEARER", ""),
) as opper:

    res = opper.stream(name="add_numbers", instructions="Calculate the sum of two numbers", input_schema={
        "properties": {
            "x": {
                "title": "X",

            },
            "y": {
                "title": "Y",
                "type": "integer",

    with res as event_stream:
        for event in event_stream:
            # handle event
            print(event, flush=True)

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a RetryConfig object to the call:

from opperai import Opper
from opperai.utils import BackoffStrategy, RetryConfig
import os


with Opper(
    http_bearer=os.getenv("OPPER_HTTP_BEARER", ""),
) as opper:

    res = opper.call(name="add_numbers", instructions="Calculate the sum of two numbers", input_schema={
        "properties": {
            "x": {
                "title": "X",
                "type": "integer",
            },
            "y": {
                "title": "Y",
                "type": "integer",
            },
        },
        "required": [
            "x",
            "y",
        ],
        "title": "OpperInputExample",
        "type": "object",
    }, output_schema={
        "properties": {
            "sum": {
                "title": "Sum",
                "type": "integer",
            },
        },
        "required": [
            "sum",
        ],
        "title": "OpperOutputExample",
        "type": "object",
    }, input={
        "x": 4,
        "y": 5,
    }, examples=[
        {
            "input": {
                "x": 1,
                "y": 3,
            },
            "output": {
                "sum": 4,
            },
            "comment": "Adds two numbers",
        },
    ], parent_span_id="123e4567-e89b-12d3-a456-426614174000", tags={
        "project": "project_456",
        "user": "company_123",
    }, configuration={},
        RetryConfig("backoff", BackoffStrategy(1, 50, 1.1, 100), False))

    # Handle response
    print(res)

If you'd like to override the default retry strategy for all operations that support retries, you can use the retry_config optional parameter when initializing the SDK:

from opperai import Opper
from opperai.utils import BackoffStrategy, RetryConfig
import os


with Opper(
    retry_config=RetryConfig("backoff", BackoffStrategy(1, 50, 1.1, 100), False),
    http_bearer=os.getenv("OPPER_HTTP_BEARER", ""),
) as opper:

    res = opper.call(name="add_numbers", instructions="Calculate the sum of two numbers", input_schema={
        "properties": {
            "x": {
                "title": "X",
                "type": "integer",
            },
            "y": {
                "title": "Y",
                "type": "integer",
            },
        },
        "required": [
            "x",
            "y",
        ],
        "title": "OpperInputExample",
        "type": "object",
    }, output_schema={
        "properties": {
            "sum": {
                "title": "Sum",
                "type": "integer",
            },
        },
        "required": [
            "sum",
        ],
        "title": "OpperOutputExample",
        "type": "object",
    }, input={
        "x": 4,
        "y": 5,
    }, examples=[
        {
            "input": {
                "x": 1,
                "y": 3,
            },
            "output": {
                "sum": 4,
            },
            "comment": "Adds two numbers",
        },
    ], parent_span_id="123e4567-e89b-12d3-a456-426614174000", tags={
        "project": "project_456",
        "user": "company_123",
    }, configuration={})

    # Handle response
    print(res)

Error Handling

Check our detailed error handling

Handling errors in this SDK should largely match your expectations. All operations return a response object or raise an exception.

By default, an API error will raise a errors.APIError exception, which has the following properties:

Property Type Description
.status_code int The HTTP status code
.message str The error message
.raw_response httpx.Response The raw HTTP response
.body str The response content

When custom error responses are specified for an operation, the SDK may also raise their associated exceptions. You can refer to respective Errors tables in SDK docs for more details on possible exception types for each operation. For example, the call_async method may raise the following exceptions:

Error Type Status Code Content Type
errors.BadRequestError 400 application/json
errors.UnauthorizedError 401 application/json
errors.NotFoundError 404 application/json
errors.RequestValidationError 422 application/json
errors.APIError 4XX, 5XX */*

Custom HTTP Client

The Python SDK makes API calls using the httpx HTTP library. In order to provide a convenient way to configure timeouts, cookies, proxies, custom headers, and other low-level configuration, you can initialize the SDK client with your own HTTP client instance. Depending on whether you are using the sync or async version of the SDK, you can pass an instance of HttpClient or AsyncHttpClient respectively, which are Protocol's ensuring that the client has the necessary methods to make API calls. This allows you to wrap the client with your own custom logic, such as adding custom headers, logging, or error handling, or you can just pass an instance of httpx.Client or httpx.AsyncClient directly.

For example, you could specify a header for every request that this sdk makes as follows:

from opperai import Opper
import httpx

http_client = httpx.Client(headers={"x-custom-header": "someValue"})
s = Opper(client=http_client)

or you could wrap the client with your own custom logic:

from opperai import Opper
from opperai.httpclient import AsyncHttpClient
import httpx

class CustomClient(AsyncHttpClient):
    client: AsyncHttpClient

    def __init__(self, client: AsyncHttpClient):
        self.client = client

    async def send(
        self,
        request: httpx.Request,
        *,
        stream: bool = False,
        auth: Union[
            httpx._types.AuthTypes, httpx._client.UseClientDefault, None
        ] = httpx.USE_CLIENT_DEFAULT,
        follow_redirects: Union[
            bool, httpx._client.UseClientDefault
        ] = httpx.USE_CLIENT_DEFAULT,
    ) -> httpx.Response:
        request.headers["Client-Level-Header"] = "added by client"

        return await self.client.send(
            request, stream=stream, auth=auth, follow_redirects=follow_redirects
        )

    def build_request(
        self,
        method: str,
        url: httpx._types.URLTypes,
        *,
        content: Optional[httpx._types.RequestContent] = None,
        data: Optional[httpx._types.RequestData] = None,
        files: Optional[httpx._types.RequestFiles] = None,
        json: Optional[Any] = None,
        params: Optional[httpx._types.QueryParamTypes] = None,
        headers: Optional[httpx._types.HeaderTypes] = None,
        cookies: Optional[httpx._types.CookieTypes] = None,
        timeout: Union[
            httpx._types.TimeoutTypes, httpx._client.UseClientDefault
        ] = httpx.USE_CLIENT_DEFAULT,
        extensions: Optional[httpx._types.RequestExtensions] = None,
    ) -> httpx.Request:
        return self.client.build_request(
            method,
            url,
            content=content,
            data=data,
            files=files,
            json=json,
            params=params,
            headers=headers,
            cookies=cookies,
            timeout=timeout,
            extensions=extensions,
        )

s = Opper(async_client=CustomClient(httpx.AsyncClient()))

Resource Management

The Opper class implements the context manager protocol and registers a finalizer function to close the underlying sync and async HTTPX clients it uses under the hood. This will close HTTP connections, release memory and free up other resources held by the SDK. In short-lived Python programs and notebooks that make a few SDK method calls, resource management may not be a concern. However, in longer-lived programs, it is beneficial to create a single SDK instance via a context manager and reuse it across the application.

from opperai import Opper
import os
def main():

    with Opper(
        http_bearer=os.getenv("OPPER_HTTP_BEARER", ""),
    ) as opper:
        # Rest of application here...


# Or when using async:
async def amain():

    async with Opper(
        http_bearer=os.getenv("OPPER_HTTP_BEARER", ""),
    ) as opper:
        # Rest of application here...

Debugging

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass your own logger class directly into your SDK.

from opperai import Opper
import logging

logging.basicConfig(level=logging.DEBUG)
s = Opper(debug_logger=logging.getLogger("opperai"))

You can also enable a default debug logger by setting an environment variable OPPER_DEBUG to true.

Development

Maturity

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

Contributions

While we value open-source contributions to this SDK, this library is generated programmatically. Any manual changes added to internal files will be overwritten on the next generation. We look forward to hearing your feedback. Feel free to open a PR or an issue with a proof of concept and we'll do our best to include it in a future release.
