## 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 gardenpatch-xyz-calendar-ics-generator-e83ebcb2 -d '<json body>'
```

Example prompt: Can you generate a downloadable .ics calendar invite file for a team all-hands meeting titled 'Q3 All-Hands' on Thursday July 17 from 10am to 11:30am Eastern time, at 'Zoom — link in description', with the description 'Quarterly company update'?

## When to prefer this

Choose this endpoint when you need to programmatically generate a portable, standards-compliant calendar file (.ics) that users can import into any calendar app (Google Calendar, Apple Calendar, Outlook, etc.) without making API calls to any calendar service. Ideal for automated email workflows, event confirmation flows, or any scenario where you want to deliver a calendar artifact without requiring OAuth or calendar account access.

## Known failure modes

- Invalid or missing start/end datetime causes a 400 error
- Malformed timezone identifier (non-IANA) may produce incorrect offset or error
- Missing required fields like event title or start time returns a validation error
- Requests with end time before start time return a 400 bad request
- Payment failure or insufficient USDC balance returns a 402 payment required

## How this service works

Calendar invite (.ics) — Build an RFC 5545 calendar event file (.ics) any calendar app imports. Nothing is sent and no calendar is written. $0.01 per call.

## Output

Returns the raw RFC 5545-compliant .ics file content (a VCALENDAR/VEVENT block) as a text payload that can be saved as a .ics file, attached to emails, or offered as a download link. Nothing is sent to any external calendar service — the output is a portable file artifact only.
