Unlocking Ad Tech Efficiency with New ARTF Standard
The IAB Tech Lab published a practical five-step guide to ARTF (Agentic Real-Time Framework), a new standard that lets vendors run decisioning logic inside programmatic auctions as sandboxed containers. ARTF operates on top of OpenRTB: containers receive bid requests, return OpenRTB Patch responses proposing intent‑tagged mutations, and communicate via gRPC or MCP. Hosts (typically SSPs or exchanges) control inputs, cryptographically verify container images, and decide which proposed mutations to apply. The guide explains how companies should evaluate use cases, design low‑latency decisioning logic, package containers to the spec, pursue certification, and partner with host platforms for deployment. Index Exchange is named as an active participant in early ARTF discussions. The spec is public (artf.ai and on GitHub) and targets auction‑time use cases such as fraud detection, identity resolution, contextual enrichment and outcome‑based optimization.
A standards body (IAB Tech Lab) published a technical specification and adoption guide enabling auction‑time containerized decisioning, which could shift programmatic architectures and affect SSPs, exchanges, identity, fraud detection and measurement workflows.

Key Takeaways & Evidence Grounding
- ARTF (Agentic Real-Time Framework) is a new IAB Tech Lab standard for running logic inside the auction in sandboxed containers.
- ARTF containers run on top of OpenRTB: they receive bid request data and return OpenRTB Patch responses proposing intent‑tagged mutations.
- Containers communicate via gRPC or MCP and container images are cryptographically verified as part of certification and signing processes.
- Host platforms (typically SSPs or exchanges) control inputs, decide which mutations to apply, and provide sandboxed execution environments.
- Index Exchange is cited as an active participant engaging partners as ARTF adoption begins; the ARTF spec is published (artf.ai and GitHub).

Revolutionizing Real-Time Bidding with Agentic RTB Framework
IAB Tech Lab published the Agentic RTB Framework (ARTF) v1.0 and opened it for public comment. ARTF defines a container-based, agent-powered architecture for real-time bidding that enables third-party service agents to be deployed into host platforms with standardized interfaces, performance guarantees, and security controls. The specification requires agents to be OCI-compliant containers manageable via Kubernetes, Docker Compose, or cloud container services (e.g., Amazon ECS), to communicate over high-performance protocols such as gRPC or MCP using protobuf serialization, and to operate without external network ingress/egress except for orchestrator communications. The framework aims to reduce integration overhead, preserve host control of data and SLAs, support composable bid-processing pipelines, and enable use cases like user-data collaboration, fraud detection, bid optimization, and supply-path optimization. Several industry companies participated in developing the specification.
Agentic Sidecar Architecture for Real-Time Programmatic Ads
IAB Tech Lab's Agentic Real-Time Framework (ARTF) v1.0 advocates a containerized "Agentic Sidecar" architecture to enable real-time, agent-driven programmatic advertising. The sidecar runs within a host platform's (DSP/SSP) virtual environment rather than calling remote cloud LLMs, addressing strict 300–500ms auction latency requirements. The specification recommends binary, high-performance communication via gRPC and Protocol Buffers (Protobuf) in place of JSON, claims up to an 80% reduction in bid request processing time, and describes atomic "Bidstream Mutations" executed in sub-millisecond windows. Governance is handled by a "Propose-and-Apply" model where agents submit intent-declared mutations (e.g., ADJUST_DEAL_FLOOR) for host approval. The sidecar is also positioned as a universal adapter for channels like DOOH and CTV by translating complex signals into OpenRTB patches. The article is authored by Gulab Patil, Founder and CEO of Lemma, and published 2026-04-30.
New Framework Promises Faster, Smarter Ad Buying Standards
On November 13, 2025, the IAB Tech Lab released Agentic RTB Framework (ARTF) v1.0 for public comment, aiming to standardize and accelerate agentic ad buying across programmatic marketplaces. The framework advocates containerizing agents so DSPs, SSPs, and data partners can operate within a unified infrastructure, reducing latency and eliminating separate data-center pinging. CEO Tony Katsur stated the goal is to enrich, inform, and analyze the bid stream by embedding logic in containerized agents. OpenRTB bid requests currently run 400–600 ms in ad serving; ARTF is expected to shorten this by bringing agents into the marketplace. Chalice’s model has been tested inside Index Exchange, showing how containerized agents could be deployed without exposing proprietary code. Index Exchange’s Joshua Prismon and Chalice CEO Adam Heimlich commented on the potential for a more efficient, interconnected agent ecosystem within the RTB stack.
