Mastra

Mastra agent runtime with TheRouter.ai models

Mastra works well with TheRouter.ai through provider adapters, letting you keep agent workflows while expanding model and provider choices.

Overview

This page mirrors the OpenRouter workflow and adapts it for TheRouter.ai. Use TheRouter.ai as your OpenAI-compatible endpoint and keep model IDs in `provider/model` format.

Installation

Install the required SDKs and keep your TheRouter.ai key in environment variables.

install.sh

npm install @openrouter/ai-sdk-provider @mastra/core

Configuration

Set TheRouter.ai base URL overrides and pass your API key. Add attribution headers when your app should appear in rankings.

TypeScript

const openrouter = createOpenRouter({ apiKey: process.env.THEROUTER_API_KEY });
const model = openrouter("anthropic/claude-sonnet-4.5");

Caveats

Integration note

When multiple agents run concurrently, set per-agent spend limits and choose model tiers explicitly to avoid runaway costs.

For production rollouts, pin SDK versions and validate model compatibility in staging before broad rollout.
