Rate limits

Each API token is rate-limited independently, on a fixed one-minute window. The limit depends on your plan:

Plan	Requests per minute (per token)
Free	60
Solo	600
Pro	600

The limit is per token, not per account — if you have multiple tokens, each gets its own allowance.

When you hit the limit

A request that exceeds the limit gets:

HTTP/1.1 429 Too Many Requests
Retry-After: 60

Retry-After tells you how many seconds to wait before the window resets. Back off for that long, then retry — the counter resets at the start of the next one-minute window rather than on a rolling basis.

Staying under the limit

• Cache responses where you can, especially for data that doesn’t change every minute (e.g. the list of monitors).
• Use a separate token per integration so a noisy script doesn’t eat the budget of something that actually needs to keep up (like a status page).
• If a legitimate use case consistently needs more headroom than your plan allows, that’s a sign to upgrade rather than to retry aggressively.
