	Description		Read-only	Idempotent	Open world
`add_brand`Start measuring a brand: does ChatGPT, Perplexity, Claude or Google AI mention it, and who does AI recommend instead? Give the brand's website (or its app store, Google Maps, YouTube or Instagram link). It reads the site, picks the buyer questions, and starts the first scan across the AI engines. Reading the site takes 1-2 minutes; if it is still running, call again with the same link and it picks up the same run, never a second one. Returns the brand_id; then use get_scan_status.

`create_prompt`Adds a buyer question to a topic so it is asked on every engine in the plan from the next run. Counts toward the plan's question limit. Calling again with the same text returns the existing question, never a duplicate.	Adds a buyer question to a topic so it is asked on every engine in the plan from the next run.

`get_fix_verification`Each fix marked shipped for the brand with its mention rate before and after and a verdict: moved (beyond normal answer churn), within_noise, or awaiting_samples.

`get_loop`The brand's loop, oldest first: each buyer question tracked, gap found, content draft created, fix published to the brand's site, fix shipped, change seen on the brand's own pages, and fix checked after it ships: a first check on day 28, re-checks on days 45, 60 and 75 and a final check on day 90 (whether it is still live and how citations, mentions and AI-referral traffic moved, each with its sample size; a horizon appears only once it has been measured). The first page also lists before_window: each question's newest draft, publish and shipped fix from before since, its current state. At most 90 days per call (the last N days is since = today minus N-1, today counted); page with next_cursor.
