$ eacc api --docs AI model release API & RSS feed — free, versioned, CORS-open

The acceleration log is available as a free RSS feed and as documented JSON endpoints — for changelogs, dashboards, bots, or a "days since the last frontier model" badge. Updated weekly, no key required. If you use it, a link back to e-acc.ai is appreciated.

$ curl feed.xml RSS feed of AI model releases

Subscribe in any reader: https://e-acc.ai/feed.xml. One item per acceleration-log event, newest first; frontier-model releases are tagged [frontier] in the title.

$ curl api/timeline.json Full timeline JSON endpoint

https://e-acc.ai/api/timeline.json — a versioned envelope over every event. CORS is open (Access-Control-Allow-Origin: *), so you can fetch it straight from a browser.

{
  "version": 1,
  "updated": "2026-07-05",
  "events": [
    { "date": "2026-06-09", "type": "model", "frontier": true,
      "title": "Claude Fable 5 ships", "detail": "...",
      "source_url": "https://..." }
  ]
}

$ curl api/latest-frontier.json Latest frontier release endpoint

https://e-acc.ai/api/latest-frontier.json — just the newest frontier-model release, for a lightweight "days since" badge or bot.

const r = await fetch("https://e-acc.ai/api/latest-frontier.json");
const { event } = await r.json();
const days = Math.floor((Date.now() - Date.parse(event.date)) / 864e5);
console.log(`${days} days since ${event.title}`);

$ cat NOTES Update cadence & stability

Data is refreshed weekly. The version field guards the shape — it only bumps on a breaking change, so you can pin against it. See the timeline for the human-readable view and pricing for model costs.
