Rate Limits
Zephex tracks usage per API key so request volume stays predictable and abuse is contained. Plan limits combine a monthly allowance with shorter burst controls.
LIMITS
| Plan | Monthly Requests | Per-minute Limit | Concurrent |
|---|---|---|---|
| Free | 300 | 10 | 1 |
| Pro | 3,000 | 60 | 3 |
| Max | 10,000 | 200 | 10 |

{ "error": "rate_limit_exceeded", "message": "Monthly limit of 300 requests reached. Upgrade to Pro for 3,000 requests.", "reset_at": "2026-05-01T00:00:00Z", "upgrade_url": "https://zephex.dev/pricing"}RESET CYCLE
Usage resets monthly on the first of each month in UTC. Usage is tracked per API key, not per account, so separate keys isolate traffic between environments and teams.
