Creative formats in AdCP use standardized asset types with well-defined properties. Assets are the discrete, typed building blocks used by formats to define requirements and by manifests to supply concrete values. Standardizing asset types ensures consistency across formats and makes requirements easier for buyers and systems to understand. ## Important: Payload vs Requirements For payload schemas (the structure of the actual asset data supplied in creative manifests), see: * [Asset Type Registry](https://adcontextprotocol.org/schemas/3.0.19/creative/asset-types/index.json) - Links to all payload schemas * Core Asset Schemas at `/schemas/3.0.19/core/assets/` - Individual asset payload definitions **Key distinction:** **Format requirements** (this document) define constraints such as: * Whether an asset is required or optional * Acceptable file or container formats * Duration, dimension, or aspect ratio limits * File size and bitrate limits * Allowed or restricted features (for tag-based assets) **Payload schemas** (core schemas) define the supplied values, such as: * `url` * `content` (for inline text or inline tag markup) * `width` / `height` (when declared) * `duration_ms` (when applicable) * `format` (declared container type) ## Asset Type Schema The official JSON schema for asset types is available at: * **Production**: [https://adcontextprotocol.org/schemas/asset-types-v1.json](https://adcontextprotocol.org/schemas/asset-types-v1.json) * **GitHub**: [https://github.com/adcontextprotocol/adcp/blob/main/static/schemas/asset-types-v1.json](https://github.com/adcontextprotocol/adcp/blob/main/static/schemas/asset-types-v1.json) ## Core Asset Types ### Video Asset Video assets represent video files with specific technical requirements. ```json theme={null} { "asset_type": "video", "required": true, "duration_seconds": 15, "acceptable_formats": ["mp4"], "acceptable_codecs": ["h264"], "acceptable_resolutions": ["1920x1080", "1280x720"], "aspect_ratio": "16:9", "max_file_size_mb": 30, "min_bitrate_mbps": 8, "max_bitrate_mbps": 10 } ``` **Properties:** * `duration_seconds`: Expected video duration * `min_duration_seconds` / `max_duration_seconds`: Duration range (if flexible) * `acceptable_formats`: Container formats (mp4, webm, mov) * `acceptable_codecs`: Video codecs (h264, h265, vp8, vp9, av1) * `acceptable_resolutions`: List of width x height strings * `aspect_ratio`: Required aspect ratio (16:9, 9:16, 1:1, etc.) * `max_file_size_mb`: Maximum file size in megabytes * `min_bitrate_mbps` / `max_bitrate_mbps`: Bitrate range in Mbps * `features`: Additional requirements (e.g., \["non-skippable", "sound on"]) ### Image Asset Static image assets for banners, logos, and visual content. ```json theme={null} { "asset_type": "image", "required": true, "width": 300, "height": 250, "acceptable_formats": ["jpg", "png", "gif"], "max_file_size_kb": 200, "animation_allowed": true } ``` **Properties:** * `width` / `height`: Dimensions in pixels * `min_width` / `min_height`: Minimum dimensions (px; typically used by responsive/sizeless formats) * `aspect_ratio`: Required aspect ratio * `acceptable_formats`: Image formats (jpg, png, gif, webp, svg) * `max_file_size_kb`: Maximum file size in kilobytes * `transparency`: Whether transparency is required/supported * `animation_allowed`: Whether animated GIFs are accepted * `notes`: Additional requirements (e.g., "Must be free of text") **Use Cases:** * Fixed layout: provide `width` and `height`. Do not include `min_width`, `min_height`, or `aspect_ratio`. * Responsive (fixed image aspect ratio): provide `min_width`, `min_height` and `aspect_ratio`. Do not include `width` or `height`. * Responsive (any image aspect ratio): provide `min_width` and `min_height` only. Do not include `width`, `height`, or `aspect_ratio`. **Note**: In fixed layouts, the image slot is an exact pixel box, so specify `width` and `height`. In responsive layouts, the renderer will resize the image; use `min_width`/`min_height` to ensure there are enough pixels for a sharp result after scaling. Use `aspect_ratio` only when the image asset itself must be a specific shape (e.g., 16:9); omit it if any image aspect ratio is acceptable ### Text Asset Text content for headlines, descriptions, CTAs, etc. ```json theme={null} { "asset_type": "text", "required": true, "text_type": "headline", "max_length": 90, "min_length": 10 } ``` **Properties:** * `text_type`: Specific type (title, headline, description, body, cta, advertiser\_name, disclaimer) * `max_length`: Maximum character count * `min_length`: Minimum character count * `default`: Default value if not provided * `allowed_characters`: Regex pattern for validation * `format`: Expected format (plain, currency, percentage) ### URL Asset Links for clickthroughs, tracking, and landing pages. Two related but distinct fields describe a URL asset: * **`url_type`** (on the manifest asset) — the **mechanism** the receiver uses to invoke this URL. * **`url-asset-requirements.role`** (on the format) — the **purpose** this URL slot serves in the creative. A slot can be `click_tracker` (purpose) and accept a `tracker_pixel` (mechanism) URL — those describe different things. #### Manifest-side: `url_type` (mechanism) Senders **SHOULD** include `url_type` on every URL asset. The valid values are: | Value | Mechanism | | ---------------- | --------------------------------------------------------------------------------------------------------- | | `clickthrough` | User-click destination (landing page or ad-tech redirector) | | `tracker_pixel` | Fires HTTP GET, expects 1×1 pixel or 204 response (impression / event / 3P trackers) | | `tracker_script` | Loads as a `
