# DeerFlow — Deep Research Agent
DeerFlow is a LangGraph-based multi-agent system running at **http://localhost:8001**.
It uses Claude Sonnet 4.6 as the primary model and Haiku 4.5 for fast sub-tasks.
## When to use
- Deep multi-step web research (competitor analysis, market research, technical surveys)
- Document analysis + synthesis across many sources
- Complex tasks that benefit from parallel sub-agent decomposition
- Generating structured reports, summaries, or slide decks from research
## Prerequisites
The DeerFlow backend must be running. Start it in a separate terminal:
```bat
cd "C:\Users\A\Documents\CURSOR PROJECTS\deer-flow"
start.bat
REM Reads your Claude Max token from ~/.claude/.credentials.json automatically
REM Backend starts at http://localhost:8001
```
No manual API key needed — it reads your Claude Max subscription token from
`C:\Users\A\.claude\.credentials.json` automatically.
## Check if running
```bash
curl -s http://localhost:8001/health || echo "DeerFlow not running"
```
## API usage (call from Claude Code)
### Send a research task
```python
import httpx, json
BASE = "http://localhost:8001"
THREAD_ID = "research-session-1"
# Create or continue a thread
resp = httpx.post(f"{BASE}/api/langgraph/threads", json={"thread_id": THREAD_ID})
# Run a task
resp = httpx.post(
f"{BASE}/api/langgraph/threads/{THREAD_ID}/runs",
json={
"assistant_id": "default",
"input": {"messages": [{"role": "user", "content": "YOUR TASK HERE"
