# List prompt results

> Per-run results for a prompt.

One row per finalised run unit (platform × country × date), newest date first, with every tracked brand's mention and the run's citations. Finalised only: after a run completes, entity adjudication can still demote a mention, so pre-finalised rows are never served. A first page whose `limit` takes more than one paging statement is checked against the brand's change token before and after the walk and walked again if it moved; a token still moving after the retries is 409 `scan_in_progress` with `Retry-After` (5s) rather than a page assembled from two scan generations — expect it while a scan of the brand runs (Pagination, above).

  title: Surfais API
  version: 1.0.0
  description: >-
    The Surfais API gives programmatic access to the AI-visibility data Surfais
    measures for your brands: organisations, brands and competitors, tracked
    prompts, per-run results and mentions, scores, share of voice and cited
    sources. It can also provision brands, manage prompts and competitors,
    request on-demand scans, and deliver signed webhooks when a scan completes
    or a score or sentiment threshold is crossed.


    Base URL: `https://api.surfais.com/v1`. Send your API key as a Bearer token
    (`Authorization: Bearer sfs_live_…`). Test keys (`sfs_test_…`) are rejected
    by the production API. Requests and responses are JSON: a success is `{
    "data": … }`, an error is `{ "error": { "code", "message" }, "request_id"
    }`.


    Guides for authentication, pagination, errors, rate limits, idempotency and
    webhooks are at https://docs.surfais.com/api/introduction.

            Every tracked brand's mention for this unit, ordered by brand_id —
            at most 250 entries: candidates are PRIORITISED for the cap —
            mentioned brands before unmentioned ones, then by position — so a
            unit that mentions more brands than the cap still loses some
            mentioned ones; when a unit holds more candidates than the cap,
            `brands_truncated` is true and `brands_total` says how many there
            were.

            How many candidate brands the unit holds in all (mentioned or not);
            equals the number of entries in `brands` unless truncated.

            True when `brands` was cut at the per-unit cap. Mentioned brands are
            prioritised for the cap, not guaranteed by it: a unit mentioning
            more brands than the cap has mentioned brands missing here, so treat
            a truncated list as the top of a ranking, never as the exhaustive
            mention list.
