.EdenaiTool¶
Note
EdenaiTool implements the standard Runnable Interface
. 🏃
The Runnable Interface
has additional methods that are available on runnables, such as with_types
, with_retry
, assign
, bind
, get_graph
, and more.
- class langchain_community.tools.edenai.edenai_base_tool.EdenaiTool[source]¶
Bases:
BaseTool
the base tool for all the EdenAI Tools . you should have the environment variable
EDENAI_API_KEY
set with your API token. You can find your token here: https://app.edenai.run/admin/account/settingsInitialize the tool.
- param args_schema: Optional[TypeBaseModel] = None¶
Pydantic model class to validate and parse the tool’s input arguments.
Args schema should be either:
A subclass of pydantic.BaseModel.
or - A subclass of pydantic.v1.BaseModel if accessing v1 namespace in pydantic 2
- param callback_manager: Optional[BaseCallbackManager] = None¶
Deprecated since version 0.1.7: Use
callbacks
instead.Callback manager to add to the run trace.
- param callbacks: Callbacks = None¶
Callbacks to be called during tool execution.
- param description: str [Required]¶
Used to tell the model how/when/why to use the tool.
You can provide few-shot examples as a part of the description.

Beta
This API is in beta and may change in the future.
Create a BaseTool from a Runnable.
as_tool
will instantiate a BaseTool with a name, description, andargs_schema
from a Runnable. Where possible, schemas are inferred fromrunnable.get_input_schema
. Alternatively (e.g., if the Runnable takes a dict as input and the specific dict keys are not typed), the schema can be specified directly withargs_schema
. You can also passarg_types
to just specify the required arguments and their types.- Parameters
args_schema (Optional[Type[BaseModel]]) – The schema for the tool. Defaults to None.
name (Optional[str]) – The name of the tool. Defaults to None.
description (Optional[str]) – The description of the tool. Defaults to None.

Beta
This API is in beta and may change in the future.
Generate a stream of events.
Use to create an iterator over StreamEvents that provide real-time information about the progress of the Runnable, including StreamEvents from intermediate results.
A StreamEvent is a dictionary with the following schema:
event
: str - Event names are of theformat: on_[runnable_type]_(start|stream|end).
name
: str - The name of the Runnable that generated the event.run_id
: str - randomly generated ID associated with the given execution ofthe Runnable that emitted the event. A child Runnable that gets invoked as part of the execution of a parent Runnable is assigned its own unique ID.
parent_ids
: List[str] - The IDs of the parent runnables thatgenerated the event. The root Runnable will have an empty list. The order of the parent IDs is from the root to the immediate parent. Only available for v2 version of the API. The v1 version of the API will return an empty list.
tags
: Optional[List[str]] - The tags of the Runnable that generatedthe event.
metadata
: Optional[Dict[str, Any]] - The metadata of the Runnablethat generated the event.
data
: Dict[str, Any]
Below is a table that illustrates some evens that might be emitted by various chains. Metadata fields have been omitted from the table for brevity. Chain definitions have been included after the table.
ATTENTION This reference table is for the V2 version of the schema.

on_chat_model_start

ChatPromptValue(messages: [SystemMessage, …])
In addition to the standard events, users can also dispatch custom events (see example below).
Custom events will be only be surfaced with in the v2 version of the API!
A custom event has following format:
Attribute
Type
Description
name
str
A user defined name for the event.
data
Any
The data associated with the event. This can be anything, though we suggest making it JSON serializable.
Here are declarations associated with the standard events shown above:
format_docs:
def format_docs(docs: List[Document]) -> str: '''Format the docs.''' return ", ".join([doc.page_content for doc in docs]) format_docs = RunnableLambda(format_docs)
some_tool:
@tool def some_tool(x: int, y: str) -> dict: '''Some_tool.''' return {"x": x, "y": y}
prompt:
template = ChatPromptTemplate.from_messages( [("system", "You are Cat Agent 007"), ("human", "{question}")] ).with_config({"run_name": "my_template", "tags": ["my_template"]})
Example:
from langchain_core.runnables import RunnableLambda async def reverse(s: str) -> str: return s[::-1] chain = RunnableLambda(func=reverse) events = [ event async for event in chain.astream_events("hello", version="v2") ] # will produce the following events (run_id, and parent_ids # has been omitted for brevity): [ { "data": {"input": "hello"}, "event": "on_chain_start", "metadata": {}, "name": "reverse", "tags": [], }, { "data": {"chunk": "olleh"}, "event": "on_chain_stream", "metadata": {}, "name": "reverse", "tags": [], }, { "data": {"output": "olleh"}, "event": "on_chain_end", "metadata": {}, "name": "reverse", "tags": [], }, ]
