What's New in IteraTools

We've been shipping fast. Here's a recap of the three most recent additions to IteraTools — the API toolkit designed for AI agents and developers who need reliable, pay-per-use tools.

📅 Google Calendar Integration (3 endpoints)

We added full Google Calendar support via the Google Calendar REST API v3. AI agents can now manage calendar events on behalf of users — all they need is an OAuth2 access token with the appropriate scope.

POST /calendar/event — Create an event 

curl -X POST https://api.iteratools.com/calendar/event \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "google_access_token": "ya29...",
    "title": "Team Standup",
    "start": "2026-03-20T10:00:00-03:00",
    "end": "2026-03-20T10:30:00-03:00",
    "description": "Daily sync",
    "attendees": ["alice@example.com"],
    "timezone": "America/Sao_Paulo"
  }'
Enter fullscreen mode Exit fullscreen mode

Response:

{
  "ok": true,
  "event_id": "abc123xyz",
  "html_link": "https://calendar.google.com/calendar/event?eid=...",
  "status": "confirmed"
}
Enter fullscreen mode Exit fullscreen mode

GET /calendar/events — List events 

curl "https://api.iteratools.com/calendar/events?google_access_token=ya29...&date_from=2026-03-01&date_to=2026-03-31" \
  -H "Authorization: Bearer YOUR_KEY"
Enter fullscreen mode Exit fullscreen mode

Returns an array of events with id, summary, start, end, location, and description.

DELETE /calendar/event — Delete an event 

curl -X DELETE https://api.iteratools.com/calendar/event \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"google_access_token": "ya29...", "event_id": "abc123xyz"}'
Enter fullscreen mode Exit fullscreen mode

Pricing: $0.003 per request.

🔧 JSON Validate/Format/Analyze — POST /json/validate

A local, zero-latency JSON tool with five modes:

Mode Description
validate Check syntax, get error location
format Pretty-print with configurable indent
minify Compact output
stats Depth, key count, type breakdown
get Extract value by dot-bracket path 
curl -X POST https://api.iteratools.com/json/validate \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "json": "{\"user\": {\"name\": \"Alice\", \"age\": 30}}",
    "mode": "stats"
  }'
Enter fullscreen mode Exit fullscreen mode

Response:

{
  "ok": true,
  "valid": true,
  "data": {
    "depth": 2,
    "keys": 3,
    "types": { "object": 2, "string": 1, "number": 1 },
    "size_bytes": 37
  }
}
Enter fullscreen mode Exit fullscreen mode

For get mode, use dot-bracket paths like user.name or items[0].id.

Pricing: $0.001 per request. Runs entirely locally — instant.

📡 RSS Feed Parser — POST /rss/fetch

The newest addition: fetch and parse any RSS 2.0 or Atom feed into normalized structured JSON. Perfect for AI agents that need to monitor content without dealing with XML parsing.

curl -X POST https://api.iteratools.com/rss/fetch \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://dev.to/feed", "limit": 5}'
Enter fullscreen mode Exit fullscreen mode

Response:

{
  "feed": {
    "title": "DEV Community",
    "description": "The most authentic, human dev community",
    "url": "https://dev.to",
    "updated": "2026-03-18T12:00:00.000Z"
  },
  "items": [
    {
      "title": "Building AI Agents with IteraTools",
      "url": "https://dev.to/example/building-ai-agents",
      "published": "2026-03-18T10:30:00.000Z",
      "summary": "In this article we explore how to use IteraTools API...",
      "author": "Jane Dev",
      "categories": ["ai", "api", "tutorial"]
    }
  ],
  "count": 5
}
Enter fullscreen mode Exit fullscreen mode

Works with both RSS 2.0 and Atom formats. The output is always the same structure regardless of the source format. Supports news sites, dev blogs, podcasts, YouTube channels, GitHub releases, and any standard feed.

Parameters:

  • url (required): The feed URL
  • limit (optional): Max items to return (default: 10, max: 50)

Pricing: $0.002 per request.

MCP Support

All three tools are available in the mcp-iteratools package (v1.0.26):

npx mcp-iteratools
Enter fullscreen mode Exit fullscreen mode

Or add to your Claude/Cursor config:

{
  "mcpServers": {
    "iteratools": {
      "command": "npx",
      "args": ["mcp-iteratools"],
      "env": { "ITERATOOLS_API_KEY": "your-key" }
    }
  }
}
Enter fullscreen mode Exit fullscreen mode
