Key Concepts
Brand identity
Brand context is provided by domain reference:
{
"brand": {
"domain": "acmecorp.com"
}
}
The agent resolves the domain to retrieve the brand's identity (name, colors, guidelines, etc.) from its brand.json file.
Format IDs
Creative format identifiers are structured objects:
{
"format_id": {
"agent_url": "https://creative.adcontextprotocol.org",
"id": "display_300x250"
}
}
The agent_url specifies which creative agent defines the format. Use https://creative.adcontextprotocol.org for standard IAB formats.
Pricing Options
Products include pricing_options array. Each option has:
pricing_option_id: Use this in create_media_buy
pricing_model: "cpm", "cpm-auction", "flat-fee", etc.
price: Base price (for fixed pricing)
floor: Minimum bid (for auction)
For auction pricing, include bid_price in your package.
Asynchronous Operations
Operations like create_media_buy and sync_creatives may require human approval. The response includes:
status: "pending" - Operation awaiting approval
task_id - For tracking async progress
Poll or use webhooks to check completion status.
Error Handling
Common error patterns:
- 400 Bad Request: Invalid parameters - check required fields
- 401 Unauthorized: Invalid or missing authentication token
- 404 Not Found: Invalid product_id, media_buy_id, or creative_id
- 422 Validation Error: Schema validation failure - check field types
Error responses include:
{
"errors": [
{
"code": "VALIDATION_ERROR",
"message": "budget must be greater than 0",
"field": "packages[0].budget"
}
]
}
Testing Mode
For testing without real transactions, agents may support:
X-Dry-Run: true header - Preview without side effects
- Test products with
test: true flag
- Sandbox environments
Ask the agent about testing capabilities before creating real campaigns.
