LivePair

ComfyUI-LivePair

ComfyUI custom nodes for LivePair AI — image and video generation across 20+ models, billed per result from prepaid credits. No subscription, no monthly tier. Renders auto-delete after 48h.

Nodes

| Node | Output | Use | |---|---|---| | LivePair Image | IMAGE + url | text-to-image, image edit, upscale, background removal | | LivePair Video | VIDEO + url | text-to-video and image-to-video (wan-3.x, seedance lines) |

Both accept an optional input image — i2i edit / i2v source frames route automatically.

Install

ComfyUI Manager — search LivePair in the node registry and click Install (registry listing). No dependencies to resolve.

Or manually:

cd ComfyUI/custom_nodes
git clone https://github.com/livepairai/ComfyUI-LivePair

Either way: zero dependencies — stdlib only, restarts not needed beyond the usual node reload.

API key

Create a prepaid lp_ key at https://livepairai.com/settings, then either:

• set env LIVEPAIR_API_KEY=lp_..., or
• paste it into the node's api_key widget

Usage

1. Add LivePair Image (or LivePair Video)
2. Pick a model from the dropdown — or leave custom and type any catalog id into model_override
3. Wire the IMAGE output into your normal pipeline (SaveImage, VAE chains, video post-processing)

Live model list + prices: GET https://livepairai.com/v1/agent/models (public, no auth). New models work immediately via model_override.

Costs

Per call, charged to your prepaid balance — images ≈ $0.02–0.05, a 5s 720p clip ≈ $0.40. Failed generations are never charged.

API surface

POST /v1/agent/generate → job → GET /v1/agent/jobs/{id} → result URL. Agents can also pay per call in USDC (x402, Base) with no key at all — see https://livepairai.com/SKILL.md and https://livepairai.com/mcp (MCP).
