Anthropic's powerful Claude AI models are available via API for developers and businesses to integrate into their applications. If you're a developer who wants to use the Claude API in your application, or if you're using Anthropic’s Claude models in your automation tools like Zapier, Make.com, or Relay.app, you'll need to purchase credits. This tutorial will guide you through the process of buying credits for the Claude API.
Step 1: Create a Claude API account
Before you can purchase credits, you'll need a Claude API account. If you don't have one already:
- Visit https://platform.claude.com/
- Follow the prompts to create your account

Step 2: Go to the API Dashboard
Once you have an account and are logged in, navigate to the API Dashboard at https://console.claude.com/dashboard.

Step 3: Navigate to Settings → Billing
In the API Dashboard:
- Navigate to settings
- Select plans and billing
Note that if you’re using the Claude API with an organization, you’ll need to be an admin or reach out to an admin to make billing changes.

Step 4: Add funds
Once you've selected a plan and added a payment method, you can add funds.

Step 5: Set up usage alerts and auto-reload
To avoid usage disruption, you can add auto-reloading when your credits dip to a specified threshold.

Step 6: Set up limits to prevent unexpected overages
Set up limits and alerts to control your costs.
Tips for managing API credits
- Use auto-reload or regularly check your credit balance to ensure uninterrupted service
- Set up usage alerts to avoid surprises
- Keep an eye on your usage patterns to optimize your model choices
- Reach out to Anthropic support if you have questions about billing or credit usage
