How this service works
Build a valid .ics document from event fields (summary, start/end, location, …).
Output
A valid iCalendar (.ics) document as text, containing the VEVENT component populated with the provided fields (summary, DTSTART, DTEND, location, description, UID, URL, PRODID, and calendar name) — ready to be attached to an email, saved to disk, or served as a downloadable file.
Example use cases
Email-ready meeting invite
“Generate an ics file for a meeting called 'Product Kickoff' on July 15th from 2pm to 3:30pm at 'One Market Street, San Francisco' — I want to attach it to an email invite.”
All-day event for shared calendar
“Make an ics file for an all-day company holiday called 'Summer Shutdown' on August 18th so I can share it with the whole team.”
Automated event confirmation workflow
“Build a .ics calendar event for 'Doctor Appointment' starting tomorrow June 12th at 9:00am and ending at 9:30am at 'City Medical Center, 450 Broadway', with the description 'Annual checkup — bring insurance card'.”
Technical details
Endpoint
POSThttps://ical.openverbs.com/v1/createWhen to prefer
Use this endpoint when you need to programmatically generate a standards-compliant .ics file from structured event data — e.g. in automated workflows that send calendar invites, confirmation emails with attachments, or any agent that needs to output a downloadable calendar event. Prefer this over manual iCal construction to avoid formatting errors and ensure RFC 5545 compliance.
Side effects
- Missing required 'summary' field returns a validation error
- Missing required 'start' field returns a validation error
- Invalid ISO datetime format for start/end causes a parse error
- summary exceeding 1000 characters is rejected
- description exceeding 10000 characters is rejected
- Payment not included or insufficient (x402) results in a 402 response
