Quadratic Conditional formats API

openapi: 3.2.0
info:
  title: Quadratic Developer Agent Connections Conditional formats API
  description: 'Token-authenticated REST API for Quadratic spreadsheets. All `/v1/*` routes require an `Authorization: Bearer <token>` header where the token is a `qdx_live_…` or `qdx_test_…` value minted from the Quadratic UI.


    **Optional `Quadratic-Session-Id` header.** Clients may attach a UUID v4 to every request to correlate analytics events from a single integration run (one client instance, one CLI invocation, one CI job). Official SDKs generate one at construction and send it transparently; direct callers may omit it. Malformed values are dropped silently and never propagated to analytics.'
