Rate Limiting

Rate limits are enforced per API key. The following headers are included in every response:

Header	Description
X-RateLimit-Limit	Maximum requests allowed in the current window
X-RateLimit-Remaining	Requests remaining in the current window
X-RateLimit-Reset	Unix timestamp when the rate limit window resets

Rate Limit Tiers

Plan	Rate Limit
Terminal + API + MCP	2,000 requests/hour
Enterprise	Higher limits or unlimited usage, negotiated per agreement

API access is available on the Terminal + API + MCP plan and above. The Terminal-only plan does not include API access. Enterprise clients receive elevated rate limits or fully unlimited usage based on their agreement, alongside dedicated support and custom data delivery options.

When you exceed the rate limit, the API returns a 429 Too Many Requests status. Wait until the time indicated by X-RateLimit-Reset before retrying.
