Prompt metrics

How each individual prompt performed over a window. Join prompt_id against List prompts for the text — this endpoint returns numbers only, so the two together are the full picture without either being heavy.

With compare_to_previous you also get a movers block: the prompts that gained and lost the most. That is usually what you actually want when a headline visibility number has moved and you need to know which questions caused it.


GET /v1/brands/{brand_id}/prompts/metrics

Authorization

Header	Type	Required
`Authorization`	`Bearer asky_sk_…`	required

Path parameters

Parameter	Type	Required	Description
`brand_id`	`uuid`	required	From List brands

Query parameters

Parameter	Type	Required	Description
`limit`	`integer`	optional	Rows per page, 1 to 100. Defaults to 20.
`cursor`	`string`	optional	Opaque cursor from the previous response. Treat it as a token, never construct one.
`start_date`	`YYYY-MM-DD`	optional	Inclusive lower bound, YYYY-MM-DD in UTC. Narrows the population before metrics are computed.
`end_date`	`YYYY-MM-DD`	optional	Inclusive upper bound, YYYY-MM-DD in UTC. Narrows the population before metrics are computed.
`compare_to_previous`	`boolean`	optional	Also return the prior equal-length period and per-row deltas.
`movers_limit`	`integer`	optional	Max gainers and losers returned, default 10.
`engine`	`string`, repeatable	optional	Restrict to these AI search engines, by slug. From List engines. Narrows the population before metrics are computed.
`country`	`string`, repeatable	optional	Restrict to these execution country codes. Narrows the population before metrics are computed.
`tag_id`	`uuid`, repeatable	optional	Restrict to prompts carrying these tags. From List tags. Narrows the population before metrics are computed.
`tag_match_mode`	`string`	optional	How to combine tag_id values. Defaults to ‘any’. One of: `any`, `all`.
`include_ads`	`boolean`	optional	Also return the advertisers running against each prompt as an `advertisers` array. Caps `limit` at 25. The advertisers array is the largest field this endpoint returns, so the default 100-row page is refused rather than truncated.

Response fields

Field	Type	Description
`data.period`	`object`	required. `{ start_date, end_date }` actually used. Defaults differ between endpoints, so read it before comparing
`data.metrics`	`object[]`	required
`data.metrics[].prompt_id`	`uuid`	required
`data.metrics[].visibility_share`	`number`	required. Share of answers to this prompt naming you
`data.metrics[].citation_rate`	`number`	required
`data.metrics[].avg_ranking`	`number \| null`	1-based, lower is better. `null` when never named
`data.metrics[].chatgpt_response_count`	`integer`	required. ChatGPT answers collected for this prompt in the window
`data.metrics[].ad_eligible_response_count`	`integer`	required. Of those, the ones in a market where OpenAI actually serves ads. The denominator behind `ad_rate`
`data.metrics[].ads_response_count`	`integer`	required. Answers that carried at least one sponsored card
`data.metrics[].ad_rate`	`number \| null`	0 to 100. `null`, not `0`, when `ad_eligible_response_count` is 0 — there is no denominator, which is different from “ads never appeared”
`data.metrics[].advertisers`	`object[]`	Present only with `include_ads`. Up to 25 `{domain, name, n, is_own_brand}`, your own brand first and then most frequent, where `n` is how many answers that advertiser appeared in. `is_own_brand` is `true` when the ad points at one of your own domains, i.e. you are bidding against your own prompt. `domain` is `null` when the card carried no link and the group fell back to the advertiser name
`data.total`	`integer`	required
`data.limit`	`integer`	required
`data.offset`	`integer`	required
`data.has_more`	`boolean`	required
`data.movers`	`object`	Only with compare. `{ top_gainers, top_losers }`
`data.newly_active`	`uuid[]`	Prompts with data this period but not the previous one
`data.newly_inactive`	`uuid[]`	The reverse. Often the more urgent list
`request_id`	`string`	required. Also returned as the `x-request-id` header. Quote it when contacting support

Errors

Status	Code	When
400	`invalid_request`	A parameter is unknown or malformed. The message names it
401	`invalid_token`	The key is missing, malformed, or does not exist
401	`token_expired`	The key passed its expiry date
401	`token_revoked`	The key was revoked
404	`not_found`	The brand does not exist, or this key is not allowed to reach it. The two are deliberately indistinguishable
429	`rate_limited`	Over 300 requests per minute. See the `Retry-After` header

Notes

A prompt with no completed execution in the window is absent, not zero. Do not read a missing row as a score of nought — it means the prompt did not run.

movers and the newly-active lists are computed over the full set, not the page you fetched. Paging never changes which prompts are reported as movers.

Rates are fractions, not percentages. 0.412 is 41.2%.
