tongflow-router-apimart

Official TongFlow plugin for APIMart — an OpenAI-compatible aggregation gateway. One API key routes to many upstream models (GPT / Claude / Gemini / Kling / Seedream / Sora / …).

This is a router-style plugin: each slot declares a model list (TONGFLOW_SLOT_MODELS), so the node shows a model dropdown next to the plugin selector and you can pick the backing model per node.

Capabilities

Implements these ABI slots (runs locally as a Python process, no GPU):

• Generate image (image-gen) — z-image-turbo (default), Seedream 4.5 / 4.0 / 5.0-Lite, Nano Banana Pro / 2 / classic (gemini-3-pro / 3.1-flash / 2.5-flash image previews), gpt-image-1-official, gpt-image-2, imagen-4.0-apimart, qwen-image-2.0, wan2.7-image, grok-imagine-1.5-apimart.
• Edit image (image-edit) — the image-capable subset of the above (Imagen 4.0 and Grok Imagine are text-to-image only).
• Generate / rewrite text (gen-text) — gpt-5 (default), gpt-5.1, gpt-5-mini, claude-sonnet-4-6, claude-opus-4-8, gemini-2.5-pro, gemini-3.5-flash, gemini-2.5-flash, deepseek-v4-pro, deepseek-r1-250528.
• Text → video (text-gen-video) — kling-v3 (default), kling-3.0-turbo, kling-v2-6, veo3.1-fast / -quality / -lite, sora-2, sora-2-pro, doubao-seedance-2.0 / -fast, doubao-seedance-1-5-pro.
• Image → video (image-gen-video) — same list minus veo3.1-lite (text-only); the input image is uploaded to APIMart first.
• Transcribe audio (transcribe) — whisper-1.
• Text → speech (text-gen-speech-preset) — gpt-4o-mini-tts (voices: alloy / echo / fable / onyx / nova / shimmer via the node's speaker field).

Image/video generation is asynchronous on APIMart's side: the plugin submits a task and polls GET /v1/tasks/{task_id}, streaming progress to the canvas. Result URLs expire within 24–72 h, so files are downloaded immediately and stored by TongFlow.
