# 🎬 Text-to-Video Animation Generator API (lucataco AnimateDiff)

## Overview
AnimateDiff turns text-to-image diffusion checkpoints into short animations. A motion module adds movement to the images that the chosen checkpoint generates from your prompt.

Pick a base checkpoint with `path`, a motion module with `motion_module`, and send a text `prompt`. Each request returns the URL of one MP4 video.

## Features
- **Five base checkpoints**: `toonyou_beta3.safetensors` (default), `lyriel_v16.safetensors`, `rcnzCartoon3d_v10.safetensors`, `majicmixRealistic_v5Preview.safetensors` and `realisticVisionV40_v20Novae.safetensors`.
- **Three motion modules**: `mm_sd_v14` (default), `mm_sd_v15` and `mm_sd_v15_v2`.
- **Prompt control**: `prompt` and a negative prompt `n_prompt`.
- **Sampling control**: `steps` (1 to 100), `guidance_scale` (1 to 10) and `seed`.

## Use Cases
1. **Animated illustrations**: short cartoon or anime-style loops from a text prompt.
2. **Stylized clips**: realistic or 3D cartoon looks by switching the base checkpoint.
3. **Social content**: quick animated visuals for posts and stories.

## Visual Examples
### Example Input
The example uses the `toonyou_beta3.safetensors` checkpoint and the `mm_sd_v14` motion module with a spring cherry blossom prompt.

```json
{
  "path": "toonyou_beta3.safetensors",
  "seed": 255224557,

## Pricing
- **Pay As You Go (PAYG) pricing**: you only pay for what you use.
- **Price**: $0.125 per API unit.
- **1 API unit = 1 successful request** that uses up to 80 seconds of processing time. A request that needs more processing time is billed one more unit for each started block of 80 seconds (for example, 81 to 160 seconds of processing is 2 units, $0.25).
- The example used 25 `steps` and took 56.3 seconds of processing. One unit covers up to 80 seconds, so higher `steps` values can push a request to 2 or more units.
- **Example cost**: the example request on this page used 56.3 seconds of processing, so it was billed 1 unit ($0.125).
- **Failed or cancelled predictions are not billed.**
- **GET requests to check prediction status** are free and don't count toward API unit usage.
- **No monthly subscription fee.**

## API Documentation

### Base URL
All API requests go to: `https://prod.api.market/api/v1/magicapi/animate-text-to-image-diffusion-lucataco-animate-diff`

### Authentication
Send your api.market API key in the `x-api-market-key` header:
```
x-api-market-key: YOUR_API_MARKET_KEY
```

### Asynchronous Processing
**IMPORTANT**: This API is asynchronous. The flow is:
1. Send a POST request to `/predictions`. A successful request returns **201 Created** with a prediction `id` and a `status` of `starting` or `processing`.
2. Poll GET `/predictions/{id}` with that ID.
3. Keep polling while `status` is `starting` or `processing`.
4. Stop when `status` is `succeeded` (read `output`), `failed` or `canceled` (read `error`).

A polling interval of 1 second and an overall timeout of 600 seconds (10 minutes) work well.

### Endpoints

#### Create a Prediction
```bash
curl -X POST "https://prod.api.market/api/v1/magicapi/animate-text-to-image-diffusion-lucataco-animate-diff/predictions" \
  -H "Content-Type: application/json" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY" \
  -d '{
    "version": "beecf59c4aee8d81bf04f0381033dfa10dc16e845b4ae00d281e2fa377e48a9f",
    "input": {
      "path": "toonyou_beta3.safetensors",
      "seed": 255224557,
      "steps": 25,
      "prompt": "masterpiece, best quality, 1girl, solo, cherry blossoms, hanami, pink flower, white flower, spring season, wisteria, petals, flower, plum blossoms, outdoors, falling petals, white hair, black eyes",
      "n_prompt": "badhandv4, easynegative, ng_deepnegative_v1_75t, verybadimagenegative_v1.3, bad-artist, bad_prompt_version2-neg, teeth",
      "motion_module": "mm_sd_v14",
      "guidance_scale": 7.5
    }
  }'
```

Response (201 Created):
```json
{
  "id": "y1pnb41b31rnc0d1d12afkcrjr",
  "version": "beecf59c4aee8d81bf04f0381033dfa10dc16e845b4ae00d281e2fa377e48a9f",
  "status": "starting",
  "created_at": "2026-10-23T10:17:40.561Z"
}
```

#### Check Prediction Status
```bash
curl -X GET "https://prod.api.market/api/v1/magicapi/animate-text-to-image-diffusion-lucataco-animate-diff/predictions/{id}" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY"
```

Response when the prediction has finished (200 OK):
```json
{
  "id": "y1pnb41b31rnc0d1d12afkcrjr",
  "status": "succeeded",
  "output": "https://blog.api.market/wp-content/uploads/2026/10/animate-diff-output-y1pnb41b-api-market.mp4",
  "error": null,
  "created_at": "2026-10-23T10:17:40.561Z",
  "started_at": "2026-10-23T10:17:58.608Z",
  "completed_at": "2026-10-23T10:18:54.917Z"
}
```

`output` is a single URL string pointing to the generated MP4 video.

### Status Codes
- **201 Created**: prediction created (POST `/predictions`). This is the normal success response.
- **200 OK**: prediction details returned (GET `/predictions/{id}`).
- **400 Bad Request**: invalid input, for example a `path` or `motion_module` that is not in the list, or `steps` above 100.
- **401 Unauthorized**: missing or invalid API key.
- **404 Not Found**: no prediction with that ID.
- **429 Too Many Requests**: rate limit exceeded.
- **500 Internal Server Error** or **503 Service Unavailable**: temporary server problem; retry later.

## Rate Limits
All plans allow 10 requests per second. Requests above that return `429 Too Many Requests`; back off before retrying and honour any `Retry-After` header. Polling a prediction with GET is free but still counts toward the per-second limit, so poll every 1 to 5 seconds rather than in a tight loop.

## Error Handling
- Check the HTTP status code of every request and read the response body for the error message.
- A prediction can also end with `status` set to `failed`; the `error` field then explains why. Failed predictions are not billed.
- Retry 429, 500 and 503 responses with exponential backoff. Fix the input before retrying a 400.

## FAQ
- **Which checkpoint should I use?**
  - `toonyou_beta3.safetensors`, `lyriel_v16.safetensors` and `rcnzCartoon3d_v10.safetensors` suit cartoon and illustration styles; `majicmixRealistic_v5Preview.safetensors` and `realisticVisionV40_v20Novae.safetensors` suit realistic styles.
- **Can a request cost more than one unit?**
  - Yes. One unit covers up to 80 seconds of processing. The example (25 steps) took 56.3 seconds; more steps take longer and can use 2 or more units.
- **How do I get the same animation again?**
  - Send the same input with a fixed non-zero `seed`. A `seed` of 0 or no seed is random.
- **Is the 201 response from POST an error?**
  - No. 201 Created means the prediction was accepted. Use the returned `id` to poll GET `/predictions/{id}` until `status` is `succeeded`, `failed` or `canceled`.
- **What if my prediction fails?**
  - Failed predictions are not billed. Read the `error` field, adjust the input and try again.
