Terms of Service
Last updated: July 2026
Service
Cardstock provides a dynamic Open Graph image generation API. You agree to use the service in compliance with all applicable laws and not to abuse the API (excessive requests, attempts to bypass rate limits, or use for illegal content).
API Keys
You are responsible for keeping your API keys confidential. Cardstock is not liable for any loss or damage arising from unauthorized use of your keys. You may revoke and regenerate keys at any time from your dashboard.
Fair Use
Free tier usage is limited to 500 requests per API key per day. We reserve the right to update rate limits and pricing with reasonable notice. Cardstock is provided "as is" during the launch period.
