Ask to be listed, or send a correction. Nothing here is taken on anyone's word: an instance is checked by our own probe, a resource is fetched, a new standard is read from its specification. No listing is paid for.

What can be listed

• Instance: your origin publishes one of the 103 standards on this map (an ard.json, an agent card, an MCP server card, llms.txt, Web Bot Auth signatures, and so on). We run the standard's probe rule against the origin; if it is found, the instance is listed as measured with the date. Check first with the live probe: tool has(origin, id) over MCP at https://agenticweb.wiki/mcp.
• Resource: an SDK, validator, registry, scanner or standards-body page about one of the standards. Listed on the resources page once fetched and read.
• Standard: a specification not yet on the map. It needs a public specification text or a fixed artifact; a product without a spec is not a row. New standards go through the verification brief, which takes longer.
• Correction: anything on the site that is wrong or out of date. Point at the page and the primary source.

Received. Instances and resources are usually checked within a week; new standards take longer. If the probe finds it, it appears on the instances page with the date it was observed.

For agents

The same request can be sent by email to info@belgravialabs.com with the origin, the standard id and an evidence URL. The standard ids are in /data/standards.json; the probe rules we will run are in /data/probes.json.
