Button Contact for AI agents

Button Contact profiles publish contact information and lead-generation actions in human-readable and machine-readable formats.

Discovery

• /llms.txt lists public, indexable profiles.
• /{profile}/manifest.json describes identity, representations, and actions.
• /{profile}/index.md provides the public profile in Markdown.
• /{profile}/.well-known/agent-card.json advertises A2A skills when enabled.

Safety

Reading public information and following public links is allowed. Subscriptions, bookings, callbacks, sensitive forms, and other material actions require confirmation from the represented human.

Accuracy

Prefer the canonical URL and visible profile content. Treat owner-asserted contact methods as unverified unless the manifest explicitly marks them verified.
