For every brand, every company, every entity on the agentic web. As autonomous agents take over navigation and decision-making, 2A Agency is the independent infrastructure that certifies your facts and identity.
Claim & Certify Your EntityThree real audits conducted in March 2026 across 3 to 4 LLMs. Every finding is sourced and verifiable.
The name of the sustainability programme EcoYellow (#FFBC1B, Pantone 116C) is absent from all tested LLMs. They describe the right facts but without the trademarked brand name — making the signature colour invisible in agentic recommendations.
Critical — visual identityChatGPT cites €8,500 for the Navitimer B01 Chronograph 43 — €1,000 below the official Breitling catalogue (March 2026: €9,500). A buyer informed by ChatGPT arrives at a retailer with an incorrect price.
Critical — product pricingThe procédure de sauvegarde ordered by the Paris commercial court on 6 October 2025 is absent from Perplexity and Gemini. 2 out of 3 LLMs present the brand as financially stable — a materially false statement.
Critical — material informationShopify and Google launched Agentic Storefronts this week — millions of merchants are now shoppable directly in ChatGPT, Gemini and Copilot via UCP (endorsed by Walmart, Target, Visa, Mastercard, Stripe). UCP standardises transactions. It does not certify brand truth.
UCP (co-developed Google/Shopify) standardises how AI agents transact with merchants — discovery, checkout, payment. It is the HTTP of agentic commerce. Live in production since March 2026.
When a ChatGPT agent searches your brand before recommending your products, it consults its training data — not your website. 2A certifies that data is accurate. We proposed extension com.2aagency.brand-certification to the UCP standard — Issue #302.
The EU AI Act requires GPAI providers to document their training data sources. Brands whose data is incorrect in these systems face reputational and commercial harm with no recourse — unless they hold an independent certified source.
Article 53 requires GPAI model providers to document their training data. A certified 2A registry constitutes an opposable reference — the brand can prove what LLMs should have known, and demonstrate good-faith corrective action.
Maximum fine for EU AI Act non-compliance. A brand whose data is hallucinated in a GPAI system without correction documentation is exposed — and cannot prove it took action.
5 standardised questions across 3 to 4 LLMs (Perplexity, Gemini, ChatGPT, Grok). Real results — no simulation. Questions cover leadership, products, pricing, sustainability, positioning.
Every LLM response is compared against official sources — brand websites, product catalogues, legal filings, Wikidata. Discrepancies are documented with evidence and date.
A JSON-LD node is published on 2aagency.com — Schema.org structured, crawlable by AI agents, with real product data (prices, SKUs) and documented hallucination warnings.
Every LLM training cycle can reintroduce drift. We re-audit quarterly and alert within 48h if certification status changes. High-risk nodes (active legal proceedings, rapid product changes): monthly.
15 real audits. Scores based on LLM scans conducted in March–April 2026. Average: 79/100. No score is estimated or fabricated.

The question is not whether AI agents talk about you. It's whether what they say is accurate.
