API Keys Setup

This page explains how to configure the Alchemy API key.

Create API Credentials

Create an API key from the official Alchemy dashboard.

Before using them in production:

• enable only the permissions you actually need
• restrict IPs when the provider supports it
• use separate keys for development and production when possible

Environment Variables

The recommended setup is environment variables:

export ALCHEMY_API_KEY="your_api_key"

No API secret, passphrase, wallet, or trading credential is used by this client.

Direct Usage

You can also pass credentials directly:

from typed_alchemy import Alchemy

async with Alchemy.new(
  api_key="your_api_key",
) as client:
  ...

Security Notes

• never commit credentials to git
• prefer read-only keys for development
• use separate keys for production automation
• rotate credentials after any suspected leak

Troubleshooting

If authenticated requests fail:

• confirm the key has the required permissions
• confirm your environment variables are loaded
• confirm the selected Alchemy app supports the network you are querying
• check Error Handling for the client error model
