> iCalendar VJOURNAL Parser is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-02).

Parses iCalendar text and extracts structured VJOURNAL (journal entry) components from it

## 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 icalendar-vjournal-parser-2d84d00a -d '<json body>'
```

Example prompt: Parse this iCalendar text for me and extract all the VJOURNAL entries: BEGIN:VCALENDAR ... END:VCALENDAR

## When to prefer this

Use this endpoint when you need to specifically extract VJOURNAL (journal entry) components from iCalendar-formatted text. Prefer the free sandbox endpoint POST /v1/sandbox/ical-vjournal first for testing. Choose this over general-purpose ical parsers when you need a lightweight, deterministic, pay-per-call service that avoids LLM overhead and guarantees consistent structured output for VJOURNAL items specifically.

## Known failure modes

- Input text is not valid iCalendar format — returns parse error
- No VJOURNAL components present in the iCalendar text — returns empty result
- Input text exceeds 100,000 character limit — rejected with validation error
- Malformed VJOURNAL blocks — may return partial results or error

## How this service works

Call when an agent needs parsed VJOURNAL items from iCalendar text. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/ical-vjournal first.

## Output

Structured representation of all VJOURNAL components found in the provided iCalendar text, including fields such as SUMMARY, DESCRIPTION, DTSTART, UID, and other standard VJOURNAL properties.
