## Quickstart

PLEXUS uses [x402](https://x402.org) — pay per call with USDC on Base. No signup required.

```bash
# Company risk score
curl -X POST https://plexus-public-production.up.railway.app/v1/products/company-risk \
  -H "Content-Type: application/json" \
  -d '{"entity": "ExxonMobil"}'
# Returns HTTP 402 with payment details → pay → retry → get scored intelligence

# Direct FEC data
curl -X POST https://plexus-public-production.up.railway.app/v1/adapters/fec \
  -H "Content-Type: application/json" \
  -d '{"params": {"type": "candidates", "name": "Sanders", "state": "VT"}}'
```

### Python Client

```python
import requests

BASE = "https://plexus-public-production.up.railway.app"

# Without x402 payment library — inspect the 402 challenge
r = requests.post(f"{BASE}/v1/products/company-risk", json={"entity": "ExxonMobil"})
print(r.status_code)   # 402
print(r.headers["X-Payment-Required"])  # payment details

# With x402 client library
# pip install x402-client
from x402 import Client
client = Client(wallet_private_key="0x...")
result = client.post(f"{BASE}/v1/products/company-risk", json={"entity": "ExxonMobil"})
print(result.json())
```
