Per-Key Request Caps

Custom per-key request caps are a Pro feature. A Pro key can be created with a cap from 100 to 1,000,000 requests. Starter keys use the fixed 100,000-request plan limit and cannot choose a custom cap. Every key still draws from the account's shared monthly allowance.

Which plans have configurable caps?

The cap option differs from the number of active keys.

Plan	Per-key behavior
Free	Fixed by plan
Starter	Fixed at plan limit
Pro	Choose 100 to 1,000,000

What happens when a key reaches its cap?

That key receives HTTP 429 even if the account still has unused monthly capacity. Other active keys can continue while shared capacity remains.

Can an existing cap be changed?

No. Revoke and recreate the key with the new cap. Roll out the replacement before revoking the old credential to avoid downtime.
