Per-key rate limits for the v2 API

You can now set request ceilings on individual API keys, directly from the dashboard. This is the most-requested control from teams running multi-tenant workloads on a shared account.

How it works

Each key inherits the account default of 100 req/s. Override any key on the Keys tab; changes take effect within a few seconds and are logged.

• Open Settings → API keys and pick a key.
• Enter a per-second ceiling and save.
• Watch live usage against the new ceiling on the same row.

# set a 250 req/s ceiling on one key
curl -X PATCH https://api.acme.dev/v2/keys/key_8f4a2 \
  -d '{ "rate_limit": 250 }'
