# API Input Parameters

> Detailed specification for DomoAI API input parameters

## Overview

DomoAI Enterprise API accepts various input types depending on the endpoint. This page provides comprehensive documentation on all supported input formats, size limits, and requirements.

## Image Inputs

Images can be provided via **domoai\_uri** or **Base64-encoded data** (for files uploaded via the [File Upload API](/guides/api-details/file-uploads)).

| Method                    | Size Limit |
| ------------------------- | ---------- |
| File Upload (domoai\_uri) | 10 MB      |
| Base64 String             | 10 MB      |

### Supported Image Formats

| Format   | File Extensions | Content Type |
| -------- | --------------- | ------------ |
| **JPEG** | `.jpg`, `.jpeg` | `image/jpeg` |
| **PNG**  | `.png`          | `image/png`  |
| **WebP** | `.webp`         | `image/webp` |
| **AVIF** | `.avif`         | `image/avif` |

<Note>
  The API validates actual image content, not just file extensions. Ensure your images are in one of the supported formats.
</Note>

### Image Input Format

#### domoai\_uri Method

For larger files, use the [File Upload API](/guides/api-details/file-uploads) to get a `domoai_uri`:

```json theme={null}
{
  "image": {
    "domoai_uri": "domoai://eyJhbGciOiJIUzI1NiIs..."
  }
}
```

#### Base64 Method

```json theme={null}
{
  "image": {
    "bytes_base64_encoded": "iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJ..."
  }
}
```

## Text Inputs (Prompts)

Prompts describe the desired output and guide the AI generation process.

### Prompt Specifications

| Format | Limit            | Details                       |
| ------ | ---------------- | ----------------------------- |

| Method                    | Size Limit |
| ------------------------- | ---------- |
| File Upload (domoai\_uri) | 80 MB      |
