API keys: authenticate REST, CLI, SDKs, and MCP

API Keys authenticate your programmatic access to LLM Pulse data. Use them with the REST API, native Rust CLI, official SDKs, MCP integration, and Looker Studio connector. Available on Scale plans and above.

The API Keys page lists every key you have created, shows its prefix and last used date, and lets you generate new keys or revoke old ones.

What it does

• Create API keys with custom names for different use cases
• Shows key prefix and last used date for identification
• Keys start with llmpulse_ prefix
• Supports revoking keys that are no longer needed

How to use it

1. Click your name/avatar at the bottom-left of the sidebar
2. Click API Keys
3. Click Create API Key and give it a descriptive name
4. Copy the full key immediately, it's only shown once
5. Use the key as a Bearer token: Authorization: Bearer llmpulse_your_key_here
6. Revoke keys you no longer need from the same page

Tips & notes

• Available on Scale plans and above
• API rate limit: 300 requests per minute per key
• Keep your API keys secret, never expose them in client-side code or public repositories
• The same key works for the REST API, native Rust CLI, official SDKs, headless MCP, and Looker Studio connector
• Each key has a prefix shown in the list for identification without revealing the full key
