How do I get an API key?

Sign up for a KeynodeCard account, go to Settings > API Keys, and create a new key. You can manage scopes and view usage from the dashboard.

What are the API rate limits?

Rate limits depend on your tier: Developer (1K/day), Startup (10K/day), Business (100K/day), Enterprise (1M/day). All tiers include burst allowances.

Is there a sandbox environment?

Yes. Use your API key with the X-Sandbox: true header to test without affecting production data. Sandbox requests don't count against rate limits.
