Pricing
fatcalendar is free: the website, REST API, MCP server and SDK cost nothing and need no account or API key.
Free
| Plan | Price | Limits |
|---|---|---|
| Everything (website, REST API, MCP, A2A, NLWeb, SDK) | 0 USD, forever, no account | 120 requests per 60 seconds per client |
There are no paid plans, no API keys and no billing. If you need much higher volume, email hello@fatcalendar.com; cached responses (Cache-Control and ETag) are the best way to reduce request counts.
