AI Agent Integration
hookstream is designed for AI agent use with three auth levels:
- Zero-auth (Agent API): POST https://hookstream.io/v1/agent/sessions — creates ephemeral webhook endpoints, no credentials needed. Sessions last 14 days, 2,000 requests.
- API Key: Full CRUD access via X-API-Key header. Get a key from the dashboard or run:
npm install -g @hookstream/cli && hookstream login (opens browser, saves key to ~/.config/hookstream/config.json)
- Environment variable: Set HOOKSTREAM_API_KEY for agent scripts. All CLI commands support --json flag for machine-readable output.
