Anthropic API key: create, add credits, troubleshoot

Anthropic setup is usually quick, but failures can come from missing credits, incorrect keys, or rate limits. Use this flow to get stable responses.

1

Create Anthropic key

  1. Open the Anthropic console and create a new API key.
  2. Store it securely and add it as ANTHROPIC_API_KEY.
  3. Restart your agent runtime after saving the key.
2

Verify credits and usage controls

Confirm your account has available credits and usage policies allow your expected request volume.

3

Troubleshoot quickly

  • authentication_error: key is missing, malformed, or from another account.
  • rate_limit_error: reduce concurrency or increase plan limits.
  • No response in app: ensure your agent is using Anthropic provider and key env var correctly.
