API Changelog Alerts
Catch the docs edit that never got a tweet. Paste the reference URL and name what counts.
API changelog alerts catch the quiet doc update that never got a launch tweet.
Vendors love a keynote. They hate a migration guide. The field that now 400s showed up as a one-line docs edit on a Tuesday. No blog post. No changelog RSS. Your on-call found it in production. That is the gap these alerts exist to close.
Where the quiet updates actually land
Look at the reference page, not the marketing site. OpenAPI files. "What's new" crumbs at the bottom of a method page. A GitHub compare on the docs repo if they publish one. Status pages lie in a different direction. They tell you the API is down. They do not tell you pagination changed.
Pixel monitors fire when a cookie banner shifts. Keyword mail fires on the word "update." You want the meaning. "List now requires a cursor. Offset is gone." That sentence is the alert. Pair the docs URL with a GitHub release watch if they also tag SDKs. Pair it with LLM alerts if the product is a model API and the news page moves first.
Write the rule in plain English
Paste the method page or the changelog index. Say what counts. "Breaking request or response changes, new required fields, removed endpoints, auth, and pricing. Ignore examples and nav." If the vendor splits docs across a dozen URLs, start with the three your app actually calls. AyeWatch is a page and topic watcher. It is not your CI suite and it will not run the SDK tests for you.

Do not alert on every code sample restyle. Do not alert on "we improved clarity" copy edits. If you do, you will mute the topic and miss the 401. Tight rules beat a firehose. If a vendor ships daily docs noise, narrow the URL to the single endpoint that can page you, and keep a weekly digest for the rest.
Make the first alert useful
Pick the API that already broke a deploy this year. Watch that page for a week. If the summary names the change you would have filed a ticket for, keep it. Then add webhook routing so the ping becomes a Linear issue instead of another badge. See webhook monitoring pipelines when you are ready to stop copy-pasting.
