Python Client SDK for Redis Agent Memory Service

redis-agent-memory

Developer-friendly & type-safe Python SDK specifically catered to leverage redis-agent-memory API.

Summary

MemoryDataPlaneServer: API for managing Agentic Memory Service (AMS) data plane operations.

SDK Installation

[!NOTE] Python version upgrade policy

Once a Python version reaches its official end of life date, a 3-month grace period is provided for users to upgrade. Following this grace period, the minimum python version supported in the SDK will be updated.

The SDK can be installed with uv, pip, or poetry package managers.

uv

uv is a fast Python package installer and resolver, designed as a drop-in replacement for pip and pip-tools. It's recommended for its speed and modern Python tooling capabilities.

uv add redis-agent-memory

PIP

PIP is the default package installer for Python, enabling easy installation and management of packages from PyPI via the command line.

pip install redis-agent-memory

Poetry

Poetry is a modern tool that simplifies dependency management and package publishing by using a single pyproject.toml file to handle project metadata and dependencies.

poetry add redis-agent-memory

Shell and script usage with uv

You can use this SDK in a Python shell with uv and the uvx command that comes with it like so:

uvx --from redis-agent-memory python

It's also possible to write a standalone Python script without needing to set up a whole project like so:

#!/usr/bin/env -S uv run --script
# /// script
# requires-python = ">=3.10"
# dependencies = [
#     "redis-agent-memory",
# ]
# ///

from redis_agent_memory import AgentMemory

sdk = AgentMemory(
  # SDK arguments
)

# Rest of script here...

Once that is saved to a file, you can run it with uv run script.py where script.py can be replaced with the actual file name.

IDE Support

PyCharm

Generally, the SDK will work well with most IDEs out of the box. However, when using PyCharm, you can enjoy much better integration with Pydantic by installing an additional plugin.

SDK Example Usage

Add a session event

Append a chat turn to a session

# Synchronous Example
from redis_agent_memory import AgentMemory, models


with AgentMemory(
    "https://api.example.com",
    store_id="<id>",
    api_key="<AGENT_MEMORY_API_KEY>",
) as agent_memory:

    res = agent_memory.add_session_event(actor_id="<id>", role=models.MessageRole.SYSTEM, content=[
        {
            "text": "<value>",
        },
    ], created_at=758464)

    # Handle response
    print(res)

The same SDK client can also be used to make asynchronous requests by importing asyncio.

# Asynchronous Example
import asyncio
from redis_agent_memory import AgentMemory, models

async def main():

    async with AgentMemory(
        "https://api.example.com",

        api_key="<AGENT_MEMORY_API_KEY>",
    ) as agent_memory:

        res = await agent_memory.add_session_event_async(actor_id="<id>", role=models.MessageRole.SYSTEM, content=[
            {
                "text": "<value>",
            },

        # Handle response
        print(res)

asyncio.run(main())

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name	Type	Scheme	Environment Variable
api_key	http	HTTP Bearer	AGENT_MEMORY_API_KEY

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

from redis_agent_memory import AgentMemory


with AgentMemory(
    "https://api.example.com",
    api_key="<AGENT_MEMORY_API_KEY>",
) as agent_memory:

    res = agent_memory.health()

    # Handle response
    print(res)

Available Resources and Operations

Available methods

AgentMemory SDK

• health - Return information about the operational status of the service.
• bulk_delete_long_term_memories - Deletes long-term memories in bulk by their IDs.
• bulk_create_long_term_memories - Creates long-term memories in bulk.
• search_long_term_memory - Runs a semantic search on long-term memory with filtering options.
• get_long_term_memory - Returns a long-term memory by its ID.
• update_long_term_memory - Partially updates a long-term memory by its ID.

Global Parameters

A parameter is configured globally. This parameter may be set on the SDK client instance itself during initialization. When configured as an option during SDK initialization, This global value will be used as the default on the operations that use it. When such operations are called, there is a place in each to override the global value, if needed.

For example, you can set storeId to "<id>" at SDK initialization and then you do not have to pass the same value on calls to operations like bulk_delete_long_term_memories. But if you want to do so you may, which will locally override the global setting. See the example code below for a demonstration.

Available Globals

The following global parameter is available. Global parameters can also be set via environment variable.

Name	Type	Description	Environment
store_id	str	The store_id parameter.	AGENT_MEMORY_STORE_ID

Example

from redis_agent_memory import AgentMemory


with AgentMemory(
    "https://api.example.com",
    store_id="<id>",
    api_key="<AGENT_MEMORY_API_KEY>",
) as agent_memory:

    res = agent_memory.bulk_delete_long_term_memories(memory_ids=[
        "<value 1>",
        "<value 2>",
        "<value 3>",
    ])

    # Handle response
    print(res)

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 redis_agent_memory import AgentMemory
from redis_agent_memory.utils import BackoffStrategy, RetryConfig


with AgentMemory(
    "https://api.example.com",
    api_key="<AGENT_MEMORY_API_KEY>",
) as agent_memory:

    res = agent_memory.health(,
        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 redis_agent_memory import AgentMemory
from redis_agent_memory.utils import BackoffStrategy, RetryConfig


with AgentMemory(
    "https://api.example.com",
    retry_config=RetryConfig("backoff", BackoffStrategy(1, 50, 1.1, 100), False),
    api_key="<AGENT_MEMORY_API_KEY>",
) as agent_memory:

    res = agent_memory.health()

    # Handle response
    print(res)

Error Handling

AgentMemoryError is the base class for all HTTP error responses. It has the following properties:

Property	Type	Description
err.message	str	Error message
err.status_code	int	HTTP response status code eg 404
err.headers	httpx.Headers	HTTP response headers
err.body	str	HTTP body. Can be empty string if no body is returned.
err.raw_response	httpx.Response	Raw HTTP response
err.data		Optional. Some errors may contain structured data. See Error Classes.

Example

from redis_agent_memory import AgentMemory, errors


with AgentMemory(
    "https://api.example.com",
    api_key="<AGENT_MEMORY_API_KEY>",
) as agent_memory:
    res = None
    try:

        res = agent_memory.health()

        # Handle response
        print(res)


    except errors.AgentMemoryError as e:
        # The base class for HTTP error responses
        print(e.message)
        print(e.status_code)
        print(e.body)
        print(e.headers)
        print(e.raw_response)

        # Depending on the method different errors may be thrown
        if isinstance(e, errors.BadRequestErrorResponseContent):
            print(e.data.title)  # str
            print(e.data.status)  # Optional[int]
            print(e.data.detail)  # Optional[str]
            print(e.data.instance)  # Optional[str]
            print(e.data.type)  # models.BadRequestErrorType

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 redis_agent_memory import AgentMemory
import httpx

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

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

from redis_agent_memory import AgentMemory
from redis_agent_memory.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 = AgentMemory(async_client=CustomClient(httpx.AsyncClient()))

Resource Management

The AgentMemory 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 redis_agent_memory import AgentMemory
def main():

    with AgentMemory(
        "https://api.example.com",
        store_id="<id>",
        api_key="<AGENT_MEMORY_API_KEY>",
    ) as agent_memory:
        # Rest of application here...


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

    async with AgentMemory(
        "https://api.example.com",
        store_id="<id>",
        api_key="<AGENT_MEMORY_API_KEY>",
    ) as agent_memory:
        # 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 redis_agent_memory import AgentMemory
import logging

logging.basicConfig(level=logging.DEBUG)
s = AgentMemory(server_url="https://example.com", debug_logger=logging.getLogger("redis_agent_memory"))

You can also enable a default debug logger by setting an environment variable AGENT_MEMORY_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.
