How this service works
Parse an .ics document into structured calendar events (summary, times, location, RRULE, attendees).
Output
Returns structured calendar event objects extracted from the raw .ics input, each containing fields such as summary/title, start datetime, end datetime, location, RRULE recurrence rule, and attendee list. Multiple VEVENT blocks in the input will be returned as separate event objects.
Example use cases
Extracting meeting details from email attachment
“I got a .ics attachment in an email for a team meeting — can you parse this iCalendar text and tell me the event title, when it starts and ends, where it's located, and who the attendees are?”
Importing recurring events from calendar export
“I exported my calendar as a .ics file and I need to pull out all the recurring events — can you parse this ics content and give me the structured event data including the RRULE recurrence rules for each event?”
Validating third-party calendar feed events
“We're ingesting calendar data from a third-party provider as raw ics text and need to extract all the event fields into structured JSON — can you parse this iCalendar document and return the summary, times, location, and attendees for each event?”
Technical details
Endpoint
POSThttps://ical.openverbs.com/v1/parseWhen to prefer
Choose this endpoint when you have raw iCalendar (.ics) text that you need converted into structured, machine-readable event data. It is ideal for processing calendar attachments, imported calendar exports, or webhook payloads from calendar systems. Prefer this over building your own ics parser or using a general-purpose LLM for calendar parsing, as it handles RRULE, attendees, and edge cases in the iCalendar RFC format reliably.
Side effects
- Malformed or invalid iCalendar text returns a parse error
- Input exceeding 200,000 characters is rejected
- Empty or missing 'ics' field causes a validation error
- iCal with non-standard or proprietary extensions may result in incomplete extraction
- Missing required DTSTART or DTEND fields in VEVENT may produce incomplete event objects
