# NetIntel ICS Calendar Generator

> NetIntel ICS Calendar Generator is a paid API for AI agents from netintel.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Converts calendar event data into a valid ICS (iCalendar) file string with quality grading and validation findings

## Facts

- Endpoint: POST https://netintel.dev/calendar/ics
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_JqcavXFL9ChBmW2Qh1Oex

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 netintel-ics-calendar-generator-f57e4120 -d '<json body>'
```

Example prompt: Can you generate an ICS calendar file for my team standup meeting on Friday June 6 at 9am to 9:30am Eastern time, titled 'Weekly Team Standup', located at Zoom Meeting Room, with a description saying 'Weekly sync for the engineering team'?

## When to prefer this

Use this endpoint when you need to programmatically generate a standards-compliant ICS/iCalendar file from structured event data, especially when quality validation and a grade score are desired alongside the output. Prefer this over manual ICS construction when correctness validation matters. Costs $0.005 USDC per successful call via x402 micropayment — no API key needed.

## Known failure modes

- Invalid or missing required event fields (title, start/end datetime) returns a validation error with no charge
- Malformed datetime formats cause input-validation rejection with no charge
- Server-side errors or upstream failures result in no charge per NetIntel policy
- Missing required POST body fields return 4xx with explanation

## How this service works

Turn event fields into a valid RFC 5545 .ics calendar file — handles timed and all-day events, escaping, line folding, and a deterministic UID for idempotent re-import — so agents can publish events that import cleanly into Google, Apple, and Outlook calendars. Add ?download=1 (or Accept: text/calendar) to receive the raw .ics file with a Content-Disposition attachment header instead of the JSON envelope. Pure compute, no LLM.

## Output

Returns a JSON object containing: the full ICS file content as a string (BEGIN:VCALENDAR...END:VCALENDAR), a unique UID for the event, a boolean indicating whether it is an all-day event, a quality grade letter (e.g. 'A'), a numeric quality score (0-100), and an array of any validation findings or issues detected.
