• Every tool passes all six checks.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work.

• run_audit

  Run a cloud audit of a website (crawl + 300+ rule analysis + report). Credits are spent as the audit runs (pay-as-you-go). The dry run is optional: pass confirm: true on the first call to start straight away. Without confirm, an audit…

• get_audit_status

  Poll a running audit by run_id (from run_audit or list_audits). Status queued/pending/running means keep polling (every 15-30 seconds): the response includes a progress field (phase, message, page/link counts) when available. Status…

• get_entity

  Get one entity as the map recorded it: the properties the map keeps (name, url, logo, image, sameAs, telephone, email, address, description), the pages that declare it, the properties whose values disagree between those pages, and the…

• get_entity_graph
