Python SDK for [EvalGuard](https://evalguard.ai) -- evaluate, red-team, and guard LLM applications with **drop-in framework integrations**.

## Installation

```bash
# Core SDK
pip install evalguardai

# With framework extras
pip install evalguardai[openai]
pip install evalguardai[anthropic]
pip install evalguardai[langchain]
pip install evalguardai[bedrock]
pip install evalguardai[crewai]
pip install evalguardai[fastapi]

# Everything
pip install evalguardai[all]
```

## Quick Start

```python
from evalguard import EvalGuardClient

client = EvalGuardClient(api_key="eg_live_...")

# Run an evaluation
result = client.run_eval({
    "model": "gpt-4o",
    "prompt": "Answer: {{input}}",
    "cases": [
        {"input": "What is 2+2?", "expectedOutput": "4"},
    ],
    "scorers": ["exact-match", "contains"],
})
print(f"Score: {result['score']}, Pass rate: {result['passRate']}")

# Check the firewall
fw = client.check_firewall("Ignore all previous instructions")
print(f"Action: {fw['action']}")  # "block"
```

---

## Framework Integrations

Every integration is a **drop-in wrapper** -- add two lines and your existing code gets automatic guardrails, traces, and observability.

### OpenAI

```python
from evalguard.openai import wrap
from openai import OpenAI

client = wrap(OpenAI(), api_key="eg_...", project_id="proj_...")

# Use exactly like normal -- guardrails are automatic
response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Hello, world!"}],
)
print(response.choices[0].message.content)
```

All calls to `chat.completions.create()` are intercepted:
- **Pre-LLM**: Input is checked for prompt injection, PII, etc.
- **Post-LLM**: Response + latency + token usage are traced to EvalGuard.
- **Violations**: Raise `GuardrailViolation` (or log-only with `block_on_violation=False`).

### Anthropic

```python
from evalguard.anthropic import wrap
from anthropic import Anthropic

client = wrap(Anthropic(), api_key="eg_...", project_id="proj_...")

response = client.messages.create(
    model="claude-sonnet-4-20250514",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Explain quantum computing"}],
)
print(response.content[0].text)
```

Intercepts `messages.create()` with the same pre/post guardrail pattern.

### LangChain

```python
from evalguard.langchain import EvalGuardCallback
from langchain_openai import ChatOpenAI

callback = EvalGuardCallback(api_key="eg_...", project_id="proj_...")

llm = ChatOpenAI(model="gpt-4o", callbacks=[callback])
result = llm.invoke("What is the capital of France?")
```

Works with **any** LangChain LLM, chat model, or chain that supports callbacks. The callback implements the full LangChain callback protocol without importing LangChain, so it is compatible with all versions (0.1.x through 0.3.x).

Traced events:
- `on_llm_start` / `on_chat_model_start` -- pre-check input
- `on_llm_end` -- log output trace
- `on_llm_error` -- log error trace

### AWS Bedrock

```python
from evalguard.bedrock import wrap
import boto3

bedrock = boto3.client("bedrock-runtime", region_name="us-east-1")
client = wrap(bedrock, api_key="eg_...", project_id="proj_...")

# invoke_model (all Bedrock model families supported)
import json
response = client.invoke_model(
    modelId="anthropic.claude-3-sonnet-20240229-v1:0",
    body=json.dumps({
        "messages": [{"role": "user", "content": "Hello"}],
        "max_tokens": 256,
        "anthropic_version": "bedrock-2023-05-31",
    }),
)

# Converse API
response = client.converse(
    modelId="anthropic.claude-3-sonnet-20240229-v1:0",
    messages=[{"role": "user", "content": [{"text": "Hello"}]}],
)
```

Supports all Bedrock model families: Anthropic Claude, Amazon Titan, Meta Llama, Cohere, AI21, and Mistral. Both `invoke_model` and `converse` APIs are guarded.

### CrewAI

```python
from evalguard.crewai import guard_agent, EvalGuardGuardrail
from crewai import Agent, Task, Crew

# Guard individual agents
agent = Agent(role="researcher", goal="...", backstory="...")
agent = guard_agent(agent, api_key="eg_...")

# Or use the standalone guardrail
guardrail = EvalGuardGuardrail(api_key="eg_...", project_id="proj_...")
result = guardrail.check("User input to validate")

# Wrap arbitrary functions
@guardrail.wrap_function
def my_tool(query: str) -> str:
    return do_search(query)
```

### FastAPI Middleware

```python
from evalguard.fastapi import EvalGuardMiddleware
from fastapi import FastAPI

app = FastAPI()
app.add_middleware(
    EvalGuardMiddleware,
    api_key="eg_...",
    project_id="proj_...",
)

@app.post("/api/chat")
async def chat(request: dict):
    # Automatically guarded -- prompt injection blocked with 403
    return {"response": "..."}
```

By default, POST requests to paths containing `/chat`, `/completions`, `/generate`, `/invoke`, or `/messages` are guarded. Customize with `guarded_paths`:

```python
app.add_middleware(
    EvalGuardMiddleware,
    api_key="eg_...",
    guarded_paths={"/api/v1/chat", "/api/v1/generate"},
)
```

For per-route control:

```python
from evalguard.fastapi import guard_route

@app.post("/api/chat")
@guard_route(api_key="eg_...", rules=["prompt_injection"])
async def chat(request: Request):
    body = await request.json()
    ...
```

### NeMo / Agent Workflows

```python
from evalguard.nemoclaw import EvalGuardAgent

agent = EvalGuardAgent(api_key="eg_...", agent_name="support-bot")

# Guard any LLM call
result = agent.guarded_call(
    provider="openai",
    messages=[{"role": "user", "content": "Reset my password"}],
    llm_fn=lambda: openai_client.chat.completions.create(
        model="gpt-4", messages=[{"role": "user", "content": "Reset my password"}]
    ),
)

# Multi-step agent sessions
with agent.session("ticket-123") as session:
    session.check("User says: reset my password")
    result = do_llm_call(...)
    session.log_step("password_reset", input="...", output=str(result))
```

## Core Guardrail Client

All framework integrations share the same underlying `GuardrailClient`:

```python
from evalguard.guardrails import GuardrailClient

guard = GuardrailClient(
    api_key="eg_...",
    project_id="proj_...",
    timeout=5.0,       # keep low to avoid latency
    fail_open=True,    # allow on error (default)
)

# Pre-LLM check
result = guard.check_input("user prompt here", rules=["prompt_injection", "pii_redact"])
if not result["allowed"]:
    print("Blocked:", result["violations"])

# Post-LLM check
result = guard.check_output("model response here", rules=["toxic_content"])

# Fire-and-forget trace
guard.log_trace({"model": "gpt-4", "input": "...", "output": "...", "latency_ms": 120})
```

## Error Handling

All integrations use **fail-open** semantics by default: if the EvalGuard API is unreachable, requests pass through rather than blocking your application.

To fail-closed:

```python
# Framework wrappers
client = wrap(OpenAI(), api_key="eg_...", block_on_violation=True)

# Core client
guard = GuardrailClient(api_key="eg_...", fail_open=False)
```

Catch violations explicitly:

```python
from evalguard import GuardrailViolation

try:
    response = client.chat.completions.create(...)
except GuardrailViolation as e:
    print(f"Blocked: {e.violations}")
```
