Webhooks.

Event	When it fires
daily.result	Every day, after a brand's AI answers are checked: its visibility and the change since the last check.
visibility.alert	When a brand's visibility moves by your alert size, or a competitor overtakes it.
brief.ready	When a content brief is ready.
post.published	When a draft is published to your CMS.

Errors and limits.

401 · Missing or wrong key

Check the header, and that the key wasn't revoked in Settings → Integrations.

402 or 403 · Plan

402 means the workspace is read-only, often a lapsed payment. 403 means the plan doesn't include the API.

404 · Not found

The brand id isn't in this workspace. Get ids from /brands.

Fair use

Data updates once a day after the checks run, so polling more than hourly won't get you anything new. Webhooks are the faster path.

Questions.

Which plans include the API?

Pro, Agency and Enterprise. Each workspace can have as many keys as it needs, and up to 50 webhooks.

Can my AI assistant use the API?

Yes, and there's an easier way. The Arrowsterr MCP server lets Claude, ChatGPT and Cursor read the same data with a sign-in button, no code needed.

How fresh is the data?

AI answers are checked every day. The daily.result webhook fires as soon as each brand's check finishes.

Can I white label it for clients?

Yes. Pull the numbers into your own client dashboards. For ready-made reports, use Client Reports in the app with your agency's logo and colors.
