# ai.txt - AI Governance Declaration
# Standard: AI-TXT/1.0 (proposed)   Author: Monop Content, Blyth, UK
# ============================================================================
#
# LICENCE: THIS STANDARD IS FREE. ALWAYS.
# Publishing an ai.txt file costs nothing and needs no permission, no
# account, and no key - exactly like robots.txt. Copy the format, put it
# on your domain, done. The format is open for anyone, forever.
# What is paid is optional: the live Verify-Endpoint that PROVES your
# declaration is true (a sealed, tamper-evident audit chain). That is free
# to start - 100 decisions, no card - and 50p per device per month at scale.
# Free to declare. Free to try. Paid only when you need proof at volume.
#
# WHAT THIS FILE IS
# robots.txt told crawlers what they may read. ai.txt declares how a
# domain's AI is governed - machine-readable, at a well-known location
# (https://yourdomain/ai.txt), verifiable by anyone in milliseconds:
# a regulator, a partner, a journalist, or another machine.
#
# As AI agents begin choosing which platforms to transact with, they will
# read this file before they read your marketing.
#
# FORMAT
# Key: Value pairs, one per line. Lines starting with # are comments.
# Keys are case-insensitive. Unknown keys must be ignored by parsers.
# A domain publishes one ai.txt at its root. That's the whole spec.
#
# VERIFICATION PRINCIPLE
# Declarations are claims. The Verify-Endpoint is what makes them
# checkable: it must return the current integrity status of the
# domain's audit record. A declaration without a verify endpoint
# is marketing. A declaration with one is accountability.

# ============================================================================
# PUBLISH YOUR OWN - FREE, NO PERMISSION NEEDED
# Copy this file. Replace the declaration section with your domain's facts.
# Delete any line you cannot back with a verify endpoint - an honest short
# ai.txt beats an aspirational long one. You never need a key or an account
# to publish one. You only pay if you use a hosted verify endpoint at scale.
# Spec discussion: contact above.
