# What is the Brand Facts Protocol (BFP)?

> Documentation index: https://brandfactsprotocol.ai/llms.txt

BFP (Brand Facts Protocol) is an open standard for publishing verifiable brand facts that AI systems can read.

Using BFP, a brand publishes one machine-readable file of sourced, timestamped facts about itself (products, pricing, leadership, locations, history) at a well-known location on its own domain. AI applications and agents read the file instead of reconstructing brand facts from scraped marketing copy and third-party pages.

BFP is a nutrition label for a brand: a standard place, a standard format, and a standard of evidence for the facts a brand puts on the record.

## What can BFP enable?

* An AI assistant answering "how much does this cost?" reads current pricing from the brand, dated and on the record, instead of a two-year-old review.
* A shopping agent checks who actually makes a product and whether a certification claim carries a source before recommending it.
* An answer engine distinguishes what a brand states about itself from what third parties say, and attributes each accordingly.
* A brand corrects a fact once, in one file, and every consuming system sees the change with a timestamp.

## Why does BFP matter?

* **Brands**: one authoritative, auditable statement of record. When AI systems describe you inaccurately, there is a canonical file to point to, with a date on every fact.
* **AI applications and agents**: a clean trust rule. Facts served from a brand's domain of record are what the brand asserts about itself, authenticated by domain control. Third-party claims carry citations or are excluded.
* **End users**: answers grounded in declared, dated, cited facts rather than stale crawled text.

## How it works

**One file.** `https://brand.com/.well-known/brand-facts.json` (root fallback: `/brand-facts.json`). Domain control is the authentication: only the party controlling the domain can serve the file, so its location is the proof of who is speaking.

**Two fact classes.** First-party facts (the brand's own affairs) are `brand-declared`. Third-party claims (awards, rankings, certifications) require an external citation URL or are excluded.

**Two access modes.** Any crawler or agent fetches the static file. A brand may additionally expose the same facts through a [Model Context Protocol](https://modelcontextprotocol.io) server implementing the standard BFP tool set. The static file remains canonical.

## Status

BFP is a v0.1 draft specification (2026-07-30), open for comment. Nothing here guarantees that any given AI system consumes the file today.
