Structural grade · AI Catalog 1.0

Near-Conformant

Correctly shaped — every hard check passes — but optional affordances are missing.

ARD conformance-test v0.9.1 (ards-project/ard-spec)

PASS

Run against this exact body with the project’s own conformance CLI.

Discovery path

ard.json

Served at /.well-known/ard.json — the path ARD v0.91 says a consumer MUST fetch.

Declared spec version

1.0

The specVersion in the manifest. 1.0 is current for the AI Catalog data model; anything lower is an earlier draft. ARD reads this field as transport-defined and ignores it.

Optional affordances missing. None of these break a client, but each one costs the publisher search relevance or verifiability.

How it is served

The publishing guide asks for three things at the transport layer, because a crawler is the consumer that matters and a crawler is a browser-shaped client.

HTTPS only — yes (HTTP 200)
Content-Type: application/json — yes
Access-Control-Allow-Origin: * — yes

Evidence. Fetched https://brandfetch.com/.well-known/ard.json on 2026-09-13, HTTP 200. The verbatim body is stored alongside its manifest in the Brand API (Brandfetch) repository as ai-catalog/brand-api-ai-catalog.json. Nothing on this page is derived or generated: an AI Catalog manifest is served from the publisher’s own domain or it does not exist, which makes it — like an A2A Agent Card — one of the few agent artifacts that cannot be produced on a provider’s behalf. Grades are recomputed on every build; the specification is a v0.9 draft and these verdicts will move when it does.

Work with this as data

Every descriptor here is available over the APIs.io API and to AI agents over MCP. Agent Discovery is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
