🛡️ agentclear-fallback — Never Let Your Agent Fail Again

Your agent crashes when it doesn't have the right tool. This package catches those failures and automatically discovers, pays for, and calls the right API through AgentClear's marketplace of 60+ services.

One line of code turns every broken agent into a capable one.

pip install agentclear-fallback

---

Quick Start

from agentclear_fallback import agentclear_fallback

@agentclear_fallback(intent="get weather data")
def get_weather(city: str):
    raise NotImplementedError("No weather API configured")

# Instead of crashing, this discovers a weather API on AgentClear,
# calls it, and returns the data:
result = get_weather("London")
print(result)  # {"temperature": 15, "condition": "Cloudy", ...}

Set your API key:

export AGENTCLEAR_API_KEY="your-key-here"

Get your key → agentclear.dev/settings/api-keys

How It Works

Your function raises an exception
         │
         ▼
   ┌─────────────┐
   │  Intercept   │  The decorator catches the error
   └──────┬──────┘
          ▼
   ┌─────────────┐
   │  Discover    │  POST /api/discover → finds the right service
   └──────┬──────┘
          ▼
   ┌─────────────┐
   │  Call        │  POST /api/proxy/{service_id} → invokes the API
   └──────┬──────┘
          ▼
   ┌─────────────┐
   │  Return      │  Response flows back as if the function worked
   └─────────────┘

No configuration. No manual API integration. Just describe what you need.

Decorator Usage

Explicit intent

@agentclear_fallback(intent="translate text between languages")
def translate(text: str, target_language: str):
    raise NotImplementedError()

result = translate("Hello!", target_language="fr")

Auto-inferred intent

The intent is derived from the function name and docstring:

@agentclear_fallback
def fetch_stock_price(ticker: str):
    """Look up the current stock price for a given ticker symbol."""
    raise NotImplementedError()

result = fetch_stock_price("AAPL")

Catch specific exceptions only

@agentclear_fallback(catch=(NotImplementedError, ConnectionError))
def get_data(query: str):
    raise NotImplementedError()

Async support

@agentclear_fallback(intent="geocode address")
async def geocode(address: str):
    raise NotImplementedError()

result = await geocode("1600 Amphitheatre Parkway")

---

LangChain Integration

Add AgentClearFallbackTool as the last tool in your agent. When the LLM can't find a matching tool, it falls through to AgentClear:

pip install "agentclear-fallback[langchain]"

from langchain.agents import initialize_agent, AgentType
from langchain_openai import ChatOpenAI
from agentclear_fallback import AgentClearFallbackTool

llm = ChatOpenAI(model="gpt-4o")

tools = [
    # ... your existing tools ...
    AgentClearFallbackTool(),  # ← always last
]

agent = initialize_agent(tools, llm, agent=AgentType.OPENAI_FUNCTIONS)

# The calculator tool handles this:
agent.invoke({"input": "What is 42 * 17?"})

# No weather tool? AgentClear handles it:
agent.invoke({"input": "What's the weather in Tokyo?"})

The tool's description is carefully crafted so the LLM knows to use it as a last resort for any API-backed task.

---

AutoGen Integration

pip install "agentclear-fallback[autogen]"

from autogen import ConversableAgent
from agentclear_fallback import get_agentclear_autogen_tool

tool = get_agentclear_autogen_tool()

assistant = ConversableAgent("assistant", llm_config={...})
user_proxy = ConversableAgent("user_proxy", human_input_mode="NEVER")

# Register the tool
assistant.register_for_llm(
    name=tool["name"],
    description=tool["description"],
)(tool["func"])

user_proxy.register_for_execution(name=tool["name"])(tool["func"])

user_proxy.initiate_chat(assistant, message="What's the weather in Tokyo?")

---

Core API

For direct usage without decorators or agent frameworks:

from agentclear_fallback import AgentClearFallback

client = AgentClearFallback()

# Discover + call in one step
result = client.discover_and_call(
    intent="get weather data",
    payload={"city": "London"}
)
print(result)

# Or step by step
service = client.discover("get weather data")
result = client.call_service(service["id"], {"city": "London"})

# Async
result = await client.adiscover_and_call("get weather data", {"city": "London"})

---

Configuration

Setting	Environment Variable	Default
API Key	AGENTCLEAR_API_KEY	(required)
Base URL	(constructor arg)	https://agentclear.dev
Timeout	(constructor arg)	30s

Logging

Enable debug logging to see discovery and call details:

import logging
logging.getLogger("agentclear_fallback").setLevel(logging.DEBUG)

Error Handling

The package raises specific exceptions you can catch:

from agentclear_fallback.core import (
    AgentClearError,            # Base exception
    AuthenticationError,        # Bad or missing API key
    InsufficientBalanceError,   # Account needs more funds
    DiscoveryError,             # No service matched the intent
    ServiceCallError,           # The API call itself failed
)

When your balance is low, the error message includes a direct link to agentclear.dev/billing so you can add funds immediately.
