This tutorial shows how to set up Keywords AI tracing with Mastro to monitor and trace your AI-powered applications.

We have built a pre-built example for you to get started quickly. You can find the code here.

Here’s the tutorial about the Mastra Weather Agent example.

​
Setup

​
1. Install Dependencies

pnpm install

​
2. Environment Variables

Copy the example environment file and add your API keys:

cp .env.local.example .env.local

Update .env.local with your credentials:

.env.local
OPENAI_API_KEY=your-openai-api-key
KEYWORDSAI_API_KEY=your-keywordsai-api-key
KEYWORDSAI_BASE_URL=https://api.keywordsai.co

​
3. Run the Project

mastra dev

This opens the Mastra playground where you can interact with the weather agent.

​
Observability

The project is configured with KeywordsAI telemetry in src/mastra/index.ts:

telemetry: {
  serviceName: "keywordai-mastra-example",
  enabled: true,
  export: {
    type: "custom",
    exporter: new KeywordsAIExporter({
      apiKey: process.env.KEYWORDSAI_API_KEY,
      baseUrl: process.env.KEYWORDSAI_BASE_URL,
      debug: true,
    })
  }
}
