Open Standard

Human Agent Protocol

An open standard for making humans' agents queryable by other humans' agents.

What is HAP?

The Human Agent Protocol (HAP) defines a simple, machine-readable file that any expert can publish at /.well-known/hap.json on their domain. It tells AI agents who the expert is, what they know, and how to query their agent endpoint.

HAP is published by the Deslop Foundation and free to adopt. Any platform, tool, or individual can implement it. There are no licensing fees, no vendor lock-in, and no gatekeepers.

  ]
}

Why HAP exists

Agents need structured sources

AI assistants today rely on scraped web pages and keyword-optimized material. HAP gives agents a direct, structured line to verified domain experts.

Experts need discoverability

Publishing a hap.json is like publishing a robots.txt — except instead of telling crawlers what to index, it tells agents what to query.

The standard should be open

No single platform should own the protocol for human-agent knowledge exchange. HAP is open-source, community-governed, and free forever.
