ACI Python SDK (BY AIPOLABS)

The official Python SDK for the ACI API. Currently in private beta, breaking changes are expected.

The ACI Python SDK provides convenient access to the ACI REST API from any Python 3.10+ application.

Documentation

The REST API documentation is available here.

Installation

pip install aci-sdk

or with uv:

uv add aci-sdk

Usage

ACI platform is built with agent-first principles. Although you can call each of the APIs below any way you prefer in your application, we strongly recommend trying the Agent-centric features and taking a look at the agent examples to get the most out of the platform and to enable the full potential and vision of future agentic applications.

Client

from aci import ACI

client = ACI(
    # it reads from environment variable by default so you can omit it if you set it in your environment
    api_key=os.environ.get("ACI_API_KEY")
)

Apps

Types

from aci.types.apps import AppBasic, AppDetails

Methods

# search for apps, returns list of basic app data, sorted by relevance to the intent
# all parameters are optional
apps: list[AppBasic] = client.apps.search(
    intent="I want to search the web",
    allowed_apps_only=False, # If true, only return apps that are allowed by the agent/accessor, identified by the api key.
    include_functions=False, # If true, include functions (name and description) in the search results.
    categories=["search"],
    limit=10,
    offset=0
)

# get detailed information about an app, including functions supported by the app
app_details: AppDetails = client.apps.get(app_name="BRAVE_SEARCH")

App Configurations

Types

from aci.types.app_configurations import AppConfiguration
from aci.types.enums import SecurityScheme

Methods

# Create a new app configuration
configuration = client.app_configurations.create(
    app_name="GMAIL",
    security_scheme=SecurityScheme.OAUTH2
)

# List app configurations
# All parameters are optional
configurations: list[AppConfiguration] = client.app_configurations.list(
    app_names=["GMAIL", "BRAVE_SEARCH"],  # Filter by app names
    limit=10,  # Maximum number of results
    offset=0   # Pagination offset
)

# Get app configuration by app name
configuration: AppConfiguration = client.app_configurations.get(app_name="GMAIL")

# Delete an app configuration
client.app_configurations.delete(app_name="GMAIL")

Functions

Types

from aci.types.functions import FunctionExecutionResult, FunctionDefinitionFormat

Methods

# search for functions, returns list of basic function data, sorted by relevance to the intent
# all parameters are optional
functions: list[dict] = client.functions.search(
    app_names=["BRAVE_SEARCH", "TAVILY"],
    intent="I want to search the web",
    allowed_apps_only=False, # If true, only returns functions of apps that are allowed by the agent/accessor, identified by the api key.
    format=FunctionDefinitionFormat.OPENAI, # The format of the functions, can be OPENAI, ANTHROPIC, BASIC (name and description only)
    limit=10,
    offset=0
)

# get function definition of a specific function, this is the schema you can feed into LLM
# the actual format is defined by the format parameter: OPENAI, ANTHROPIC, BASIC (name and description only)
function_definition: dict = client.functions.get_definition(
    function_name="BRAVE_SEARCH__WEB_SEARCH",
    format=FunctionDefinitionFormat.OPENAI
)

# execute a function with the provided parameters
result: FunctionExecutionResult = client.functions.execute(
    function_name="BRAVE_SEARCH__WEB_SEARCH",
    function_parameters={"query": {"q": "what is the weather in barcelona"}},
    linked_account_owner_id="john_doe"
)

if result.success:
    print(result.data)
else:
    print(result.error)

Utility functions

to_json_schema

Convert a local python function to a LLM compatible tool schema, so you can use custom functions (tools) along with ACI.dev functions (tools).

from aci import to_json_schema

# dummy function to test the schema conversion
def custom_function(
    required_int: int,
    optional_str_with_default: str = "default string",
) -> None:
    """This is a test function.

    Args:
        required_int: This is required_int.
        optional_str_with_default: This is optional_str_with_default.
    """
    pass

# for openai chat completions api
custom_function_openai_chat_completions = to_json_schema(custom_function, FunctionDefinitionFormat.OPENAI)
"""result:
{
    "type": "function",
    "function": {
        "name": "custom_function",
        "description": "This is a test function.",
        "parameters": {
            "properties": {
                "required_int": {
                    "description": "This is required_int.",
                    "title": "Required Int",
                    "type": "integer"
                },

                    "type": "string"

)

Agent-centric features

The SDK provides a suite of features and helper functions to make it easier and more seamless to use functions in LLM powered agentic applications. This is our vision and the recommended way of trying out the SDK.

Meta Functions and Unified Function Calling Handler

We provide 4 meta functions that can be used with LLMs as tools directly, and a unified handler for function calls. With these the LLM can discover apps and functions (that our platform supports) and execute them autonomously.

from aci import meta_functions

# meta functions
tools = [
    meta_functions.ACISearchApps.SCHEMA,
    meta_functions.ACISearchFunctions.SCHEMA,
    meta_functions.ACIGetFunctionDefinition.SCHEMA,
    meta_functions.ACIExecuteFunction.SCHEMA,
]

# unified function calling handler
result = client.handle_function_call(
    tool_call.function.name,
    json.loads(tool_call.function.arguments),
    linked_account_owner_id="john_doe",
    allowed_apps_only=True,
    format=FunctionDefinitionFormat.OPENAI
)

There are mainly two ways to use the platform with the meta functions, please see agent patterns
