ComfyUI nodes

comfyui-livepair is a set of custom nodes that call the LivePair API from inside a ComfyUI graph. Generation runs hosted — no local checkpoints or CUDA for the LivePair steps — and bills the same prepaid lp_ balance as the Studio and the REST API. Zero dependencies: stdlib HTTP only, torch/PIL come from ComfyUI itself.

Install

  • ComfyUI Manager — search LivePair in the node registry and click Install (listing).
  • Manual — cd ComfyUI/custom_nodes && git clone https://gitlab.com/livepairai/comfyui-livepair

Reload nodes after install; no pip step needed.

Credentials

Generate an lp_ key on the billing page (see API keys), then either:

  • set LIVEPAIR_API_KEY in the ComfyUI environment, or
  • paste the key into the node's api_key widget input.

Nodes

NodeOutputMaps to
LivePair ImageIMAGE + urlPOST /v1/agent/generate (t2i / i2i edit / upscale / remove-bg)
LivePair VideoVIDEO + urlPOST /v1/agent/generate (t2v / i2v)
LivePairRefreshModels—GET /v1/agent/models — refreshes dropdown choices from the live catalog

Both generator nodes accept an optional input image — attach one and the request routes to i2i edit / i2v source frames automatically. The custom model option plus model_override accepts any current id from the catalog, so newly added models work without a node update.

Billing & retention

  • Per-result pricing from prepaid credits — the catalog page shows the per-resolution/duration price for every model before you run it.
  • Hosted renders auto-delete on a fixed retention window (shown on the models pages and in the privacy policy) — save outputs locally.
  • Long-running jobs poll server-side (up to ~10 min) inside the node; a failed or timed-out job raises in ComfyUI like any node error.
