# Nansen API
Use this skill when you have Nansen API credentials.
## When to use
- The task needs Nansen smart-money or on-chain analytics endpoints.
- A paid/enterprise key is expected.
- You need a configurable request runner before endpoint templates are finalized.
## Quick start
```bash
export NANSEN_API_KEY="..."
export NANSEN_BASE_URL="https://api.nansen.ai"
python3 scripts/nansen_request.py /health --method GET --pretty
```
## Workflow
1. Set `NANSEN_API_KEY` and `NANSEN_BASE_URL`.
2. Default auth header is `apikey`; set `NANSEN_API_KEY_HEADER` if your account expects another header.
3. Start with a capability probe endpoint.
4. Store endpoint-specific payload templates under `references/` as they are confirmed.
