audit.domains

Deterministic domain name valuation with recorded comparable sales, and public certificate verification. Start with the free static surfaces: every published name has its figures at https://audit.domains/domain/{name}/index.json (no key, no credit, no server computation; the published names are the /domain/ URLs in https://audit.domains/sitemap.xml). For any other name, the hosted MCP server in supportedInterfaces answers without a key with a cached result, the catalog figure, or a report link where the engine runs in the reader's browser. Only a fresh server-side appraisal is metered: it needs an ad_live_ API key and spends one API credit. This card is discovery only: audit.domains does not run an A2A task endpoint, and every skill below is an MCP tool.

Skills

• Appraise a domain name
  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 needs an ad_live_ key and spends one credit. 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).
