AI-to-AI Communication Protocols

How AI systems discover, understand, and exchange data with websites without human intervention.

Discovery Protocols

AI agents discover sites through standardized entry points:

  • /ai/manifest.json — Primary discovery endpoint
  • robots.txt — Crawler directives and sitemap links
  • /llm.txt — Human-readable summary for language models
  • Schema.org WebSite markup in HTML

Data Exchange Formats

  • JSON-LD — Linked data for semantic relationships
  • JSON endpoints — Structured data at predictable URLs
  • Schema.org vocabulary — Shared semantic language for entities

Trust & Authentication

The Digital Karma Web Federation uses transparent trust scoring rather than cryptographic authentication. Sites earn trust through measurable quality signals — Schema coverage, endpoint completeness, content freshness, and federation participation. The score is public and verifiable by any agent.
