API Keys

API keys authenticate SDK telemetry. Each key is scoped to one project.

1. Create a project

Projects isolate telemetry. Create one from the workspace switcher or the projects page.

2. Generate an API key

Open Configure → API Keys in the sidebar and click Create key. The raw key is shown once — copy it immediately.

3. Use the API key

Pass the key to the SDK. Never commit keys to source control.

PROMPTLAYER_API_KEY=pl_live_your_key_here
PROMPTLAYER_PROJECT_ID=1

const promptlayer = new PromptLayer({
  apiKey: process.env.PROMPTLAYER_API_KEY!,
  projectId: process.env.PROMPTLAYER_PROJECT_ID!,
})

4. Revoke an API key

Revoked keys stop accepting telemetry immediately. Revoke from the API Keys page if a key is exposed. Generate a new key and update your environment.
