How this service works

216 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

Output

Returns a JSON object containing: the full iCalendar (.ics) text (VCALENDAR block), a base64-encoded data URI suitable for embedding in HTML or email attachments, and a suggested filename (e.g. 'event-title.ics'). The .ics content is compatible with Google Calendar, Microsoft Outlook, and Apple Calendar.

Example use cases

Agent-sent meeting invite

“Generate a .ics file for a client kickoff meeting called 'Project Kickoff' on November 5, 2026 at 2:00 PM UTC, lasting 60 minutes, with the Zoom link https://zoom.us/j/123456789 and location 'Online', so I can attach it to my email.”

Webinar scheduling from agent

“Create a calendar invite for a public webinar titled 'AI Trends 2027' starting January 15, 2027 at 6:00 PM UTC, running 90 minutes, with description 'Join us for a live discussion on AI trends' and link https://webinar.example.com.”

Recurring team reminder event

“Make a .ics calendar event for a 'Monthly Review' on December 1, 2026 at 10:00 AM UTC, 45 minutes long, at our office on '123 Main St, San Francisco', with a note saying 'Bring your Q4 reports'.”

Technical details

Endpoint

GEThttps://fastx402.tools/ics-event?utm_source=zero.xyz

When to prefer

Use this endpoint when an AI agent needs to programmatically create a standard calendar invite file that users can import into any major calendar app. It is the right choice when you need a portable, universally compatible .ics file rather than using a calendar provider's proprietary API (which would require OAuth and user credentials). Ideal for agent-initiated scheduling flows, email attachments, or event reminders without requiring access to the recipient's calendar system.

Side effects

Missing required 'title' or 'start' parameters returns an error
Malformed UTC datetime format (non-ISO 8601) may result in an invalid event
Payment failure (x402) prevents the call from completing
Invalid duration_minutes value (non-numeric) may be ignored or cause an error
