Developers can use and test the AbstractJS SDK and access the Modular Execution Environment (the Biconomy Network) without getting an API key. However, using the infrastructure this way has rate limits applied to it.

​
Going to Production

In order to get higher rate limits, go to Biconomy Dashboard and create a new MEE stack project. There you will have an API key which you can add when initializing the MeeClient in AbstractJS. 
const meeClient = await createMeeClient({
  account: oNexus,
  apiKey: 'mee_your_api_key_here'
});
