Installation
pip install raxe
Basic Usage
from raxe import AsyncRaxe
async_raxe = AsyncRaxe()
# Single scan
result = await async_raxe.scan("test prompt")
if result.has_threats:
print(f"Threat: {result.severity}")
Batch Scanning
Scan multiple prompts efficiently:from raxe import AsyncRaxe
async_raxe = AsyncRaxe()
prompts = [
"What is AI?",
"Ignore all instructions",
"Tell me about Python",
]
# Scan all with concurrency control
results = await async_raxe.scan_batch(
prompts,
max_concurrency=5
)
for prompt, result in zip(prompts, results):
status = "THREAT" if result.has_threats else "SAFE"
print(f"{status}: {prompt[:30]}...")
Async Context Manager
from raxe import AsyncRaxe
async with AsyncRaxe() as raxe:
result = await raxe.scan("test")
# Cleanup handled automatically
Integration with FastAPI
from fastapi import FastAPI, HTTPException
from raxe import AsyncRaxe
app = FastAPI()
raxe = AsyncRaxe()
@app.post("/chat")
async def chat(prompt: str):
result = await raxe.scan(prompt)
if result.has_threats:
raise HTTPException(
status_code=400,
detail=f"Threat detected: {result.severity}"
)
response = await generate_response(prompt)
return {"response": response}
Integration with aiohttp
import aiohttp
from raxe import AsyncRaxe
async def process_requests(prompts: list[str]):
raxe = AsyncRaxe()
async with aiohttp.ClientSession() as session:
for prompt in prompts:
result = await raxe.scan(prompt)
if not result.has_threats:
async with session.post(api_url, json={"prompt": prompt}) as resp:
yield await resp.json()
Streaming Support
from raxe import AsyncRaxe
async def scan_stream(prompts):
raxe = AsyncRaxe()
for prompt in prompts:
result = await raxe.scan(prompt)
yield {
"prompt": prompt[:50],
"safe": not result.has_threats,
"severity": result.severity
}
Performance Tuning
from raxe import Raxe
from raxe.sdk.agent_scanner import AgentScannerConfig, create_agent_scanner
# Option 1: Background mode (non-blocking, recommended for async apps)
raxe = Raxe()
scanner = create_agent_scanner(
raxe,
AgentScannerConfig(
execution_mode="background", # Returns in <1ms
on_threat="log",
),
)
scanner.scan_prompt(text) # Fire-and-forget
# Option 2: L1-only for fast inline results
raxe = Raxe(l2_enabled=False) # ~5-15ms per scan
result = raxe.scan(text)
# Option 3: scan_fast() convenience method
result = raxe.scan_fast(text) # L1-only, ~5-15ms
Error Handling
from raxe import AsyncRaxe, RaxeBlockedError, RaxeException
async def safe_scan(prompt: str):
raxe = AsyncRaxe()
try:
result = await raxe.scan(prompt)
return result
except RaxeBlockedError as e:
# Handle blocked threats
return {"blocked": True, "severity": e.severity}
except RaxeException as e:
# Handle other errors
return {"error": str(e)}
Comparison: Sync vs Async
| Feature | Sync (Raxe) | Async (AsyncRaxe) |
|---|---|---|
| Single scan | raxe.scan() | await raxe.scan() |
| Batch | Loop | scan_batch() |
| Concurrency | Thread pool | Native async |
| Use case | Simple apps | High-throughput APIs |
What’s Next
