 | `placement_id` | string | Yes | Placement identifier from the publisher's placement registry in `adagents.json`. One placement per request. |
 | `seller_agent_url` | string (URI) | Yes | API endpoint URL of the seller agent issuing this request. The provider resolves the active package set it has synced for this seller against it; an unsynced seller MUST yield an empty offer set, never a fall-back to another seller's set. A single per-placement value carrying no user identity. Compared with AdCP URL canonicalization. Consistent with `seller_agent_url` on the Identity Match request and `agent_url` in `adagents.json`. |
 | `artifact` | Artifact | No | Full content artifact adjacent to this ad opportunity. Same schema as content standards evaluation. The publisher sends the full artifact when they want the buyer to evaluate the actual content. Contractual protections govern buyer use. TEE deployment upgrades contractual trust to cryptographic verification. |

When present, routers MUST use this value instead of their default. `0` disables caching (e.g., when targeting configuration has just changed); schema-enforced maximum is 86400 seconds. See [Caching](#caching). |
