Monitoring 50+ API changelogs in real time

Know about breaking
API changes hours before
your code does.

Third-party APIs ship breaking changes without warning. Your team finds out when production breaks at 2 AM. APIDelta monitors 50+ API changelogs every hour, uses AI to classify what matters, and alerts your team in Slack or email — before anything breaks.

Features

Stop reading changelogs manually

APIDelta crawls changelogs, classifies what changed, and sends the right alert to the right engineer — end to end.

AI-Powered Classification

AI reads every changelog entry and classifies it as breaking, deprecation, or informational — so you only act on what matters.

Slack and Email Alerts

Route critical changes to Slack for instant visibility, and batch lower-severity updates into email digests. Set severity thresholds per channel so the right signal reaches the right place.

50+ Changelog Formats

HTML pages, RSS feeds, GitHub Releases — we handle the messy reality of how APIs publish changes. Paste a URL and APIDelta figures out the rest.

Built for Teams

Assign API ownership to the engineers who maintain each integration. Route alerts to the right people and share a single change feed with clear severity badges.

Hourly Monitoring

APIDelta checks every monitored API on the hour. When a breaking change lands, you know within 60 minutes — not when your CI pipeline fails at 2 AM.

Full Audit Trail

Every change, every classification, every alert — logged and searchable. When a post-mortem asks "did we know about this?", the answer is in your dashboard.

How it works

Set up in under 2 minutes

1

Paste your changelog URLs

Add the changelog URL for any third-party API your product depends on. Stripe, Twilio, GitHub, OpenAI, and 50+ more work out of the box — any URL with a changelog works.

2

AI reads and classifies every update

Each changelog entry gets a severity level, affected endpoints, and a plain-English summary. No more skimming release notes — your team sees exactly what matters.

3

Get alerted before things break

When a breaking change drops, you get a Slack message or email with exactly what changed, which endpoints are affected, and what to do next.

FAQ

Frequently asked questions

What APIs can APIDelta monitor?
Any API that publishes a changelog, release notes, or status page. We handle HTML pages, RSS feeds, and GitHub Releases out of the box. If it has a URL, APIDelta can crawl it.
How does the AI classification work?
APIDelta uses AI to read each changelog entry and classify it by type (breaking, deprecation, non-breaking, informational) and severity (critical, high, medium, low). It also extracts affected endpoints and generates a plain-English summary your whole team can act on.
How is this different from basic change detection tools?
Most monitoring tools charge $149-749/mo for basic text diffing with no intelligence layer. APIDelta uses AI to understand what changed and whether it affects your integration — at a fraction of the cost. You get smarter alerts for less money.
Do I need to install anything?
Nothing. APIDelta is fully hosted. Sign up, paste your API changelog URLs, configure your alert channels, and you are done. No agents to deploy, no SDKs to integrate, no CI plugins to maintain.
What happens during the free trial?
You get 14 days of full Pro access with up to 3 monitored APIs. No credit card required. At the end of the trial, pick a plan or your monitoring pauses — we never delete your data.
Can I filter which changes trigger alerts?
Yes. Alert rules support severity thresholds (e.g., only critical and high), specific API filters, and keyword matching. Route different alert types to different Slack channels or email addresses.
Is my data secure?
All data is encrypted in transit (TLS) and at rest. APIDelta only stores changelog content and your alert configuration — never your source code or API keys. Each team's data is fully isolated.

Your next API outage is preventable.

Engineering teams lose an average of 4 hours per incident caused by surprise API changes. Start monitoring in under 2 minutes — no credit card required, nothing to install.
