# AgentsToolsHub iCalendar Generator

> AgentsToolsHub iCalendar Generator is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-17).

Converts a JSON array of calendar events into a valid RFC 5545 .ics file with proper CRLF line endings, text escaping, line folding, and DTSTAMP, importable into Google Calendar, Outlook, and Apple Calendar.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentstoolshub-icalendar-generator-9a28696f
```

Example prompt: Turn these JSON events into a valid .ics calendar file I can import into Google Calendar: [{"title":"Team Standup","start":"2025-06-10T09:00:00","end":"2025-06-10T09:30:00"},{"title":"Product Review","start":"2025-06-11T14:00:00","end":"2025-06-11T15:00:00"}] — name the calendar 'Work Schedule'.

## When to prefer this

Use this endpoint when you need to programmatically convert structured JSON event data into a standards-compliant .ics file that can be universally imported by any RFC 5545-compatible calendar application. Prefer it over manual calendar entry or proprietary calendar APIs when portability across Google Calendar, Outlook, and Apple Calendar is required without authentication or calendar-API credentials.

## Known failure modes

- Malformed or invalid JSON in the events parameter returns an error
- Missing required event fields (e.g. no start time) may produce incomplete VEVENT blocks
- Very large event arrays may hit query string length limits for a GET request
- Events with special characters that cannot be escaped correctly may cause parsing failures in some calendar clients

## How this service works

Generate a valid RFC 5545 iCalendar file from JSON events: proper CRLF line endings, text escaping, line folding at 75 octets and a required DTSTAMP. The output imports cleanly into Google Calendar, Outlook and Apple Calendar. Use this when an agent needs to jSON events → valid .ics calendar file.

## Output

Returns a valid RFC 5545 iCalendar (.ics) file as text, with VCALENDAR and VEVENT blocks, correct CRLF line endings, text escaping, 75-octet line folding, and a DTSTAMP on every event — ready to be saved as a .ics file and imported into Google Calendar, Outlook, or Apple Calendar.
