Give your key a descriptive name (e.g., "ProRank SEO")

Important Considerations

Cost Management

Monitor your usage regularly. Set spending limits in your provider's dashboard to avoid unexpected charges.

Security

Never share API keys. Use environment variables in production. Rotate keys regularly.

Performance

Start with smaller, cheaper models. Upgrade only when you need advanced capabilities.

Rate Limits

Each provider has rate limits. Plan your usage to stay within these limits.
