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 your 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 get email alerts for important updates. Set severity thresholds per rule so the right signal reaches the right place.
HTML, RSS & GitHub Releases
Paste a changelog URL and APIDelta parses it automatically. Supports standard HTML changelog pages, RSS/Atom feeds, and GitHub Release pages.
Team Ownership
Assign each API to the engineer who owns that integration, and route alerts by source, severity, or keyword. The right person gets paged — and nobody else gets noise.
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. Hourly on every plan; faster cadence available on Business.
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.
MCP server
Query API changes from Claude or Cursor.
APIDelta exposes a Model Context Protocol server. Connect once with a per-team API key — your AI assistant can pull recent changes, search the changelog, and list catalogued sources without leaving the editor.

How it works
Set up in under 2 minutes
Pick from 39 monitored APIs (or paste any URL)
Start from our curated catalog — Stripe, OpenAI, Anthropic, GitHub, Twilio, Cloudflare, AWS, and 32 more — pre-vetted with the right parser already wired up. Or paste any HTML changelog, RSS/Atom feed, or GitHub Releases URL when your stack runs on something we haven't catalogued yet.
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.
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.
Product tour
From changelog URL to Slack alert
Watch the full flow: add an API, see AI-classified changes, and get alerted — all in under 30 seconds.
Interactive demo with sample data from Stripe, Twilio, Cloudflare, Slack, and OpenAI changelogs.
See it in action
From raw changelog → classified alert.
We crawl the page, an LLM judges severity and pulls out affected endpoints, and you get a structured alert in Slack — not a raw diff to parse at 2 AM.
<article class="changelog-entry"> <h3>2026-03-15 · API</h3> <p>The <code>source</code> parameter on <code>/v1/payment_intents</code> is now removed.
