Ctxfy API

API for AI context management — spaces, sources, artifacts, and file uploads.

Overview

Ctxfy provides HTTP API access for AI context management: save conversation state as snapshots, extract structured context and artifacts, organize work in Spaces. The API is available on Pro and Enterprise plans. All routes under /v1 require authentication.

Use Quickstart to integrate in minutes. For authentication details, see Authentication.

Why Ctxfy?

Stop losing hours to AI context recovery. Ctxfy helps you:

  • Resume in 30 seconds — Turn re-reading 200-message threads into a single paste. Extract critical state from old chats into compact, reusable snapshots.
  • Cut token costs by 65–75% — Compress conversation state by 3–4×. Fit more relevant information into one prompt without burning tokens on repetition.
  • Find code in seconds — Auto-extract code, schemas, and diagrams. Searchable artifacts instead of scrolling through hundreds of messages.
  • Works with any AI — ChatGPT, Claude, Gemini, Llama. Provider-agnostic; your context travels with you.
