# AI Video Editing API

> Apply effects, transitions, face-swaps, and motion controls to existing videos via MuApi.ai — Wan Effects, Luma Reframe, dance, dress-change, and more.

## Overview

Take a video as input and transform it: cinematic effects, face swap, dress change, dance motion, reframing, and lipsync are all single-API-call operations. Useful for social-content automation, ad variants, and post-production at scale.

- Effects: wan-effects, video-effects, image-effects, dance
- Face & body: face-swap, dress-change
- Reframing & motion: luma-reframe, luma-modify
- All exposed through the same submit-and-poll JSON API

## API Pattern

Every model in this category uses the same submit-then-poll API:

```http
POST https://api.muapi.ai/api/v1/{model}
x-api-key: YOUR_API_KEY
Content-Type: application/json
```

Response: `{ "request_id": "abc123", "status": "processing" }`. Poll `GET https://api.muapi.ai/api/v1/predictions/{request_id}/result` until `status` is `completed` — the result URLs are in the `outputs[]` array. Optionally pass `?webhook=https://your-server` on the submit call to receive a callback instead of polling.

Get an API key at https://muapi.ai/access-keys.

## Quick Start

```bash
# 1. Submit
REQUEST_ID=$(curl -s -X POST https://api.muapi.ai/api/v1/video-effects \
  -H "x-api-key: $MUAPI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"apply a cinematic teal-and-orange grade"}' | jq -r .request_id)

# 2. Poll
while :; do
  RESP=$(curl -s https://api.muapi.ai/api/v1/predictions/$REQUEST_ID/result -H "x-api-key: $MUAPI_API_KEY")
  STATUS=$(echo "$RESP" | jq -r .status)
  [ "$STATUS" = "completed" ] && echo "$RESP" | jq .outputs && break
  [ "$STATUS" = "failed" ] && echo "$RESP" && exit 1
  sleep 3
done
```

## FAQ

**What's the maximum input video length?**

Most video-edit models cap at 10-15 seconds of input. Pre-trim before submitting for best results.

**Can I batch-process a directory of videos?**

Yes — submit each one through the API and track via the request IDs. The MuApi CLI (`muapi mcp serve`) wraps this for agentic batch flows.

## Agent Integration

MuApi ships an MCP server so agents (Claude Code, Cursor, custom) can call every model in this category as a tool:

```bash
npm install -g muapi-cli
muapi auth login
muapi mcp serve  # exposes all MuApi models as MCP tools
```
