Limits apply per key. Each key has a per-minute request limit. Paid plans also include a monthly call allowance. See the pricing page for plan prices.
Plan limits
| Limit | Pro | Enterprise |
|---|---|---|
| Requests per minute | 300 | 1,000 |
| Included calls per month | 5,000 | 100,000 |
| Prediction window (hours) | 24 | 168 |
| Bulk airports per request | 0 | 50 |
Free keys
Agent keys and MCP tokens are limited to 30 requests per minute. They reach only the free endpoints.
Over the limit
A request over the per-minute limit returns HTTP 429 with this body:
{
"success": false,
"error": { "code": "RATE_LIMIT_EXCEEDED", "message": "Maximum <n> requests per minute" }
}Wait until the next minute, then retry. Do not retry in a tight loop.
Historical data and predictions
Historical patterns use the last 30 days of data on all plans. The lookbackDays field reports the plan label and does not change the window. The prediction window depends on the plan. The table above shows it for each plan.
