This endpoint lists the websites (hosts) that AI answers cite for the prompts of a domain. Each row has the number of citations, the number of prompts, the share of all citations and the owner of the website.

The owner field has one of three values:

  • own: the website of the brand.
  • competitor: the website of a tracked competitor.
  • third_party: any other website.

The list starts with the most-cited website. The response is paginated. To see the URLs on one website, use GET /api/v1/citations with cited_domain.

Authorizations

header
Authorizationstring
Required

Your API key in the format Bearer ak_live_<your-key>. Create a key in the dashboard under Settings → Developers.

header
X-Request-Idstring

An optional UUID for log correlation. If you do not send one, the server makes one and returns it in the response.

Query parameters

query
domain_idstring
Required

The UUID of the domain. Find domains with GET /api/v1/domains. If you do not send it, the endpoint returns 400.

query
daysinteger

The look-back window in days, from 1 to 365. The default is 30. The server uses the exact value. It does not round it to a fixed bucket.

query
start_datestring

The first day of a fixed window, in the format YYYY-MM-DD. Send it with end_date. When you send both dates, they replace days.

query
end_datestring

The last day of a fixed window, in the format YYYY-MM-DD. The day is included. A window can be at most 365 days.

query
topic_idsarray

Topic UUIDs from GET /api/v1/topics. Repeat the parameter for each value, for example topic_ids=a&topic_ids=b. The endpoint then counts only the prompts in these topics.

query
tag_idsarray

Tag UUIDs from GET /api/v1/tags. Repeat the parameter for each value. If you send topic_ids and tag_ids, the endpoint counts the prompts that match either filter.

query
pageinteger

The page number. The first page is 1. The default is 1.

query
sizeinteger

The number of rows on each page, from 1 to 500. The default is 100.

query
freshboolean

Set true to skip the cache and calculate the result again. The new result replaces the cached result. The default is false.

Response

dataobject
Required

One page of cited websites.

itemsarray
Required

The cited websites on this page, from the most citations to the fewest.

totalinteger
Required

The number of cited hosts on all pages.

pageinteger
Required

The page number from the request.

sizeinteger
Required

The page size from the request.

total_pagesinteger
Required

The number of pages. It is 1 when the list is empty.

generated_atstring
Required

The ISO-8601 time when the server made (or cached) this response.

domain_idstring
Required

The domain from the request.

daysinteger
Required

The days value from the request.

Response headers

HeaderDescription
X-CacheHIT, MISS or REFRESH. REFRESH means that you sent fresh=true.
X-Request-IdThe request id. If you sent one, the server returns it.
X-RateLimit-LimitThe maximum number of requests per minute for this key.
X-RateLimit-RemainingThe number of requests that remain in this minute.
X-RateLimit-ResetThe Unix time in seconds when the window starts again.

Caching

The server caches the response for 1 hour for each set of parameters. The full list is also cached, so other pages of the same query are fast. To get new data before the cache expires, send fresh=true.

Errors

400 Bad Requesterror

The domain_id query parameter is missing. Or start_date is after end_date, or the window is longer than 365 days. If a date is not in the format YYYY-MM-DD, or page, size or days is out of range, the endpoint returns 422.

401 Unauthorizederror

The API key is missing, malformed or revoked.

403 Forbiddenerror

The developer_access flag of the team is off. Or the domain is not in the scope of your key, or your allowed_domains list does not include it.

404 Not Founderror

The domain_id is malformed or does not exist, or your user is not a member of its team.

429 Too Many Requestserror

You sent too many requests. Read the Retry-After header to know how long to wait.

Empty result

If the window has no citations, or the filters match no prompts, the endpoint returns 200 with an empty list:
