## Before you call it

1. Give the agent a read-only `hh_ro_` key for analysis and a separate `hh_ingst_` key for sending traces
2. Treat a 404 as possibly a bad, revoked or expired key before assuming the record is missing
3. Set `limit` on `POST /v1/events/search`. The default is 1,000 rows
4. Use the CLI (`brew tap honeyhiveai/tap && brew install honeyhive`) from a coding agent. It maps one command to each API endpoint
5. Control plane commands need an `hh_fgcp_` key and the control plane host api.cp.us.honeyhive.ai

## Connect

```bash
curl https://api.dp1.us.honeyhive.ai/v1/datasets -H "Authorization: Bearer $HH_API_KEY"
```
