Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-deployer-x402-deployer-workers-dev-0e9810fa -d '<json body>'
```

Example prompt: Take this CSV of events — columns are title, date, start_time, location, notes — and convert it into a .ics calendar file I can import into Google Calendar or Outlook, treating any event without a time as all-day and defaulting to 1-hour duration for timed events.

## When to prefer this

Choose this endpoint when you need a pure, serverless CSV-to-ICS conversion with no external API dependencies, auto-detection of common column names, support for both all-day and timed events, configurable delimiters, and RFC 5545 compliance for broad calendar app compatibility. Ideal when you already have event data in CSV/spreadsheet form and need a calendar file without setting up a full calendar service.

## Known failure modes

- CSV exceeds 1000 rows — truncation or rejection
- Ambiguous or missing date column — parsing error returned
- Malformed date/time values in CSV rows — individual events may be skipped or errored
- Unrecognized delimiter — parse failure
- Missing required summary/date columns with no explicit mapping — mapping error

## How this service works

CSV to ICS / CSV to iCal / calendar file generator / .ics builder / Google Calendar + Outlook + Apple Calendar import. RFC 5545 compliant VCALENDAR/VEVENT output. Auto-detects column mapping (summary, date, time, location, description) or accepts an explicit mapping. Handles all-day and timed events, configurable default duration, custom delimiters. Up to 1000 rows. Pure parser, no upstream API.

## Output

Returns an RFC 5545-compliant VCALENDAR/VEVENT ICS file with one VEVENT per CSV row, including SUMMARY, DTSTART, DTEND (or DATE for all-day events), LOCATION, and DESCRIPTION fields as mapped from the CSV columns. Up to 1000 events per call.
