This is what you actually get

Not a dashboard to check. An alert that finds you, and an API you can pipe anywhere.

Three steps, then never think about it again

The whole product is setup-and-forget. There is no dashboard to babysit.

1

Pick your providers

Choose the APIs your product actually depends on. Takes about a minute.

2

We read the changelogs

Every 6 hours, each official feed is fetched and diffed entry by entry — then classified BREAKING, DEPRECATION or NOTICE.

3

Only the serious stuff reaches you

Notices are archived silently. Breaking changes and deprecations hit your inbox, Slack, or your own systems via the API.

Cheaper than one minute of incident response

One missed deprecation costs days of firefighting and an apology to customers. Insurance starts at nothing.

Honest answers

How fast are alerts, really?

Every provider is checked every 6 hours. Pro and Team alerts send the moment a change is detected in that cycle. Free accounts get a Monday digest. We say 6 hours rather than "real-time" because that's the truth.

Won't this just spam me?

No. Only BREAKING and DEPRECATION changes trigger an email. Routine NOTICE items are archived and available through the API but never interrupt you. Most weeks you'll hear nothing — that's the product working.

I signed up and got an "API key" — what do I do with it?

It's just your password. Paste it at apisunset.com/account to tick which APIs you want watched — that takes about a minute and it's the only setup there is. After that you can forget the key entirely; alerts arrive in your inbox on their own. Developers can also use it as a normal API token to pull changes into their own tools, but that's optional.

What if my provider isn't listed?

Ask and it usually gets added within a few days. The registry grows every week, and requests from customers are how it grows.

Can I pipe this into Slack or Jira?

Yes. Team plan webhooks are Slack- and Discord-compatible out of the box, and the JSON payload works with any custom receiver, so you can auto-create tickets.

Why should I trust a new product with this?

Straight answer: API Sunset is new, so there are no customer logos to show you yet. That's why the free tier is genuinely free and needs no card — try it on your three riskiest dependencies and judge it on whether the alerts are useful. If they aren't, you've lost nothing.

What happens to my data?

We store your email, which providers you watch, and a hashed version of your API key. Card details never touch our systems — Stripe handles those. We don't sell data or run tracking cookies. Full detail in the privacy policy.

Three providers, free forever, no card. If it ever saves you one incident, it paid for a decade of itself.
