# 🧊 3D Reconstruction API (Meta MapAnything)

## Overview
MapAnything is a 3D reconstruction model from Meta. Its developer describes it as universal feed-forward metric 3D reconstruction: it builds a 3D model of a scene from a set of views in a single pass. This listing is packaged by vufinder.

Send image files, a video, or JSON files for images with geometric input in `inputs`. Video is sampled every `sampling_rate` frames. Inputs are padded to one aspect ratio and resized to at most 518 pixels. The API returns a GLB mesh, a GLB point cloud and one JSON file of prediction data per image or sampled frame.

## Features
- **Images or video**: `inputs` accepts JPG, JPEG, PNG and WEBP images, MP4, AVI and MOV videos, and JSON files for images with geometric input.
- **Frame sampling**: `sampling_rate` (default 24) keeps every n-th video frame; the first and last frames are always included.
- **Mesh and point cloud**: `return_mesh` and `return_pcd` (both default `true`) return GLB files you can open in common 3D viewers.
- **Per-frame data**: `data` holds one JSON file per image or sampled frame. `to_base64` (default `true`) stores arrays as base64 strings with shape and dtype; `keys_to_exclude` drops keys you do not need.
- **Extra point attributes**: `normals` computes normals for the point cloud and `point_scales` computes a depth-based scale per point.
- **Transparent images**: `alpha_blend_onto` (default `white`) sets how alpha channels are handled.

## Use Cases
1. **Scene capture**: turn a walk-around video of a room, object or site into a 3D mesh and point cloud.
2. **3D assets from photos**: build a first 3D model of a real place from a handful of photos.
3. **Robotics and mapping**: produce 3D structure from camera footage for planning or analysis.
4. **AR and VR prototypes**: import the GLB files into 3D tools and engines to place content in a captured scene.

## Visual Examples
### Example Input
One short video in `inputs`, sampled every 24 frames, with the mesh and point cloud turned on:

[Watch the example input video](https://blog.api.market/wp-content/uploads/2026/10/map-anything-input-api-market.mp4)

```json
{
  "inputs": [
    "https://blog.api.market/wp-content/uploads/2026/10/map-anything-input-api-market.mp4"
  ],
  "to_base64": true,
  "return_pcd": true,
  "return_mesh": true,
  "sampling_rate": 24,
  "keys_to_exclude": "",
  "alpha_blend_onto": "white"
}
```

### Example Output
The request returned:

- `mesh`: a GLB mesh of the scene (about 41.5 MB).
- `point_cloud`: a GLB point cloud (about 17.4 MB).
- `data`: 9 JSON files, one per sampled video frame, with the prediction arrays as base64 strings.

The GLB files are too large to preview on this page; open them in any 3D viewer that reads GLB.

## Input Parameters
| Field | Type | Required | Default | Allowed values | Description |
| --- | --- | --- | --- | --- | --- |
| `inputs` | array of URLs | Yes | none |  | Input file URLs: JPG, JPEG, PNG or WEBP images, MP4, AVI or MOV videos, or JSON files for images with geometric input. Images and sampled video frames are padded to one aspect ratio and resized to a maximum dimension of 518 pixels. |
| `sampling_rate` | integer | No | `24` |  | For video inputs, keep every n-th frame. The first and last frames are always included. |
| `return_pcd` | boolean | No | `true` |  | Whether to return a point cloud file |
| `return_mesh` | boolean | No | `true` |  | Whether to return a mesh file |
| `alpha_blend_onto` | string | No | `white` | `keep`, `white`, `black`, `mean` | How to handle images with an alpha channel. `mean` blends the image onto the ImageNet mean RGB values; `keep` keeps the original pixel values. |
| `normals` | boolean | No | `false` |  | Whether to compute normals for the point cloud |
| `point_scales` | boolean | No | `false` |  | Whether to compute a scaling factor for each point based on its depth |
| `keys_to_exclude` | string | No | `""` |  | Comma-separated list of keys to leave out of the output JSON files |
| `to_base64` | boolean | No | `true` |  | Whether to store the arrays in the JSON files as base64 strings with shape and dtype |

## Pricing
- **Pay As You Go (PAYG) pricing**: you only pay for what you use.
- **Price**: $0.02 per API unit.
- **1 API unit = 1 successful request with up to 18 seconds of processing.** A request that takes longer is billed one more unit for each started block of 18 seconds (for example, 37 seconds of processing is 3 units, $0.06).
- More images, longer videos or a lower `sampling_rate` (more frames) take longer to process and can use more units.
- **Example cost**: the example request above took 9.6 seconds of processing, so it used 1 API unit and cost $0.02.
- **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/3d-reconstruction-api-vufinder-map-anything`

### 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/3d-reconstruction-api-vufinder-map-anything/predictions" \
  -H "Content-Type: application/json" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY" \
  -d '{
    "version": "bb68c254a65d3ce6b173909181d2dfbd044300b3ebca25ab63f07aa7eb1eebff",
    "input": {
      "inputs": [
        "https://blog.api.market/wp-content/uploads/2026/10/map-anything-input-api-market.mp4"
      ],
      "to_base64": true,
      "return_pcd": true,
      "return_mesh": true,
      "sampling_rate": 24,
      "keys_to_exclude": "",
      "alpha_blend_onto": "white"
    }
  }'
```

Response (201 Created):
```json
{
  "id": "ce129p03qsrmy0d1d1c9g7zjwg",
  "version": "bb68c254a65d3ce6b173909181d2dfbd044300b3ebca25ab63f07aa7eb1eebff",
  "status": "starting",
  "created_at": "2026-10-23T10:39:21.186Z"
}
```

#### Check Prediction Status
```bash
curl -X GET "https://prod.api.market/api/v1/magicapi/3d-reconstruction-api-vufinder-map-anything/predictions/{id}" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY"
```

Response when the prediction has finished (200 OK, `data` shortened to 3 of its 9 files):
```json
{
  "id": "ce129p03qsrmy0d1d1c9g7zjwg",
  "status": "succeeded",
  "output": {
    "data": [
      "URL of the JSON file for frame 1",
      "URL of the JSON file for frame 2",
      "URL of the JSON file for frame 3"
    ],
    "mesh": "URL of the GLB mesh file",
    "point_cloud": "URL of the GLB point cloud file"
  },
  "error": null,
  "created_at": "2026-10-23T10:39:21.186Z",
  "started_at": "2026-10-23T10:41:06.520Z",
  "completed_at": "2026-10-23T10:41:16.077Z"
}
```

`output` is an object. `data` is a list of JSON file URLs, one per image or sampled frame. `mesh` and `point_cloud` are GLB file URLs, or `null` when `return_mesh` or `return_pcd` is `false`.

### 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 missing `inputs` list or an `alpha_blend_onto` value that is not in the list.
- **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
- **What can I send in `inputs`?**
  - Image URLs (JPG, JPEG, PNG, WEBP), video URLs (MP4, AVI, MOV) or JSON files for images with geometric input. Each input is padded to one aspect ratio and resized to at most 518 pixels.
- **How many frames are used from a video?**
  - Every n-th frame, set by `sampling_rate` (default 24), plus the first and last frames. The example video gave 9 frames and 9 JSON files in `data`.
- **What file format are the 3D outputs?**
  - `mesh` and `point_cloud` are GLB files. In the example they were about 41.5 MB and 17.4 MB. Set `return_mesh` or `return_pcd` to `false` if you do not need one of them.
- **How is a request billed?**
  - $0.02 per request for up to 18 seconds of processing, plus one unit for each further started block of 18 seconds. The example video took 9.6 seconds and cost $0.02.
- **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.
