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, and there are three ways to pay: no key, $5 by card through POST https://audit.domains/api/machine/resolve (action card_checkout, then card_status; a person pays on a Square page; terms and open lanes: GET the same URL), a funded agent account (a human operator loads a prepaid balance and grants the agent a limit at https://audit.domains/machine-account; the agent then buys under that grant with no person present), or an ad_live_ API key that 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.
