audit.domains
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Appraise a domain name appraise_domain
Deterministic fair value with a published low/high interval, scored factors and the closest recorded comparable sales. The same name always returns the same figure. Free for a published name at https://audit.domains/domain/{name}/index.json. MCP tool appraise_domain: without a key it returns a cached result, the catalog figure or a report link; a fresh server run is $5 by card with no key (POST https://audit.domains/api/machine/resolve, action card_checkout) or one credit on an ad_live_ key. A user who was quoted a price: link https://audit.domains/check/?d={name}&ask={whole US dollars}, which runs in their browser with no account and no credit. Whether the owner marked a name for sale in its DNS: https://audit.domains/for-sale/{name} (?format=json for programs).
