Koala Io Rate Limits

Koala publishes NO numeric request-per-second or per-minute rate limit for any endpoint, and returns NO rate-limit response headers. The documented constraints are payload-shape caps on /batch and /accounts/batch (30 events, 30 identifies, 30 page_views per request, one person per request), a 50-email cap on the deletion endpoint, and plan-level monthly quotas (credits, webhooks, alerts, automated outbound). Throttling is expressed commercially rather than in the protocol.

Koala Io Rate Limits is the machine-readable rate-limit profile for Koala on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 11 rate-limit definitions, measuring events, identifies, page_views, profiles, and emails.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Buyer Intent, Ingestion, Rate Limiting, Quotas, and Throttling.

Limits

Events per request request
events
30
/batch and /accounts/batch accept up to 30 events per request.
Identifies per request request
identifies
30
Up to 30 identify objects per /batch or /accounts/batch request.
Page views per request request
page_views
30
Up to 30 page_view objects per /batch request. Not available on /accounts/batch.
Same-person constraint request
profiles
1
All events/identifies in a single /batch request must belong to one person.
Emails per deletion request request
emails
50
The Deletion API silently ignores emails beyond the first 50 in a request — it does not reject the request.
Enrichment credits account
credits
plan
Reveal/Enrich and ZoomInfo enrichment consume plan credits.
Included seats account
seats
plan
Additional seats purchasable on Starter and above.
Automation webhooks account
webhooks
1000
"1k webhooks/mo" is published in the Workflow Automation section of the plan comparison table on paid tiers. The table is rendered column-major, so per-tier attribution below Growth could not be read with confidence — recorded as a published paid-tier quota.
Slack alerts account
alerts
250
"250 Alerts / mo" published in the plan comparison table. Same column-attribution caveat as the webhook quota.
Automated outbound actions account
actions
100
"100/mo" published against automated outbound in the plan comparison table. Same column-attribution caveat.
Data retention account
months
plan
Not a rate limit but the hardest ceiling in the product — on Free and Starter, collected data is only retained one month.

Policies

User-Agent Required
Requests without a User-Agent header may be flagged as bots and dropped. The response is still 200; there is no error and no counter.
Idempotency
Send a message_id per event to dedupe replayed/retried deliveries. identifies[] and page_views[] have no dedupe key.
Backoff Strategy
No published guidance. Clients should implement exponential backoff with jitter on 429 and treat Retry-After as absent.
