  "description": "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.",
