# Agentmap directive

**Agentmap** is a line a publisher can add to `robots.txt`, of the form `Agentmap: https://example.com/entries.json`, that points a crawler at a source of Agentic Resource Discovery (ARD) entries as an alternative to relying solely on the well-known manifest path. It is defined in the ARD specification itself (v0.91, §5.1, 26 August 2026) as one of five discovery mechanisms alongside the well-known manifest, in-page JSON-LD markup, an HTML `<link rel="ard">` tag, and DNS service-binding records; a conforming consumer is only required to fetch `/.well-known/ard.json` and honour `rel="ard"`, so `Agentmap:` is a convenience a crawler may use, not something it must support. It is not part of RFC 9309 (the Robots Exclusion Protocol), so a robots.txt parser that does not know ARD is free to ignore the line, and no major AI crawler is documented as consuming it. Used by: ard.
