openapi: 3.2.0
info:
title: Chronary Agents API
version: 1.0.0
description: 'Calendar-as-a-service API for AI agents.
Manage calendars, events, and availability for AI and human agents.
All endpoints require an API key passed as a Bearer token.
**Authentication:** `Authorization: Bearer chr_sk_...` or `Authorization: Bearer chr_ak_...`
**Rate limit:** 10 requests/second per API key. Exceeds return HTTP 429.
**Quotas:** Monthly operation limits by plan — see Billing & plans and Rate limits.
**Agent bootstrap:** Custom extensions prefixed `x-agent-*` describe the self-signup flow for AI agents. These are not part of any registered OpenAPI extension — they are a Chronary convention.'
