Inspect rank movement — HTTP

Read how source ranks move between a reference and checkpoint run. Method: GET Path: /projects/{project_id}/runs/{run_id}/rank-displacement Use the HTTP base for your authorized environment and an Authorization: Bearer header. See authentication and HTTP setup.

Parameters

This table covers the standard read profile. It excludes internal application routes and advanced analysis controls.

Name	Location	Type	Required	Default	Meaning
`project_id`	path	string	Yes	—	Project ID from list_projects. Select the project in the intended workspace and environment.
`run_id`	path	string	Yes	—	Run ID from list_runs for this project. Use the exact returned value and check readiness before reading measurements.
`aggregation_level`	query	string	No	`"domain"`	domain requests source-domain results; url requests individual-page results. Keep the same reporting unit when comparing measurements.
`group_by`	query	string	No	`null`	JSON-encoded array. Split results into rows by the requested dimensions. Check both filters_applied.group_by and each row’s group_by_values before labeling the groups.
`filters`	query	string	No	`null`	JSON-encoded array. Select measured answers with objects containing dimension and values. Use labels from list_dimension_options; inspect returned warnings for filters that were not applied.
`reference`	query	string	No	`null`	JSON-encoded object. Choose the comparison run: previous_run, first_run, or specific_run. For specific_run, include run_id. The request’s run_id is the checkpoint.
`subject`	query	string	No	`null`	JSON-encoded object. Choose sources with kind: leaderboard, all, owned, or specified. For specified, provide domains containing exact source keys for the requested reporting unit.

Request example

Set IQRUSH_API_BASE and IQRUSH_ACCESS_TOKEN through secure configuration. Replace project/run IDs and sample selections with values returned by your account. JSON objects and arrays are encoded as query strings.

curl --fail-with-body --silent --show-error --get \
  --header "Authorization: Bearer ${IQRUSH_ACCESS_TOKEN}" \
  --header "Accept: application/json" \
  --data-urlencode aggregation_level=domain \
  --data-urlencode 'reference={"type":"previous_run"}' \
  --data-urlencode 'subject={"kind":"owned"}' \
  "${IQRUSH_API_BASE%/}/projects/${IQRUSH_PROJECT_ID}/runs/${IQRUSH_RUN_ID}/rank-displacement"

Read the response

Read data.domain_details for rank movement, data.tier_events for entries and exits across the reported evidence boundary, and data.n_changed_domains for the combined changed-domain count. Retain available intervals and correction metadata. Rank displacement and citation-share change are not interchangeable. A selected subject can return only part of the landscape.

Fields to use

These selected fields explain the example and the result to preserve. Field presence depends on the response; this is not a complete response schema.

Field	Meaning and use
`data.domain_details[].domain_or_url`	Source whose rank movement is reported.
`data.domain_details[].rank_baseline`	Rank in the reference measurement.
`data.domain_details[].rank_checkpoint`	Rank in the checkpoint measurement.
`data.domain_details[].rank_displacement`	Rank comparison with difference, uncertainty, and comparability. A positive rank-number change means a lower position.
`data.domain_details[].entered`	Whether the source entered the comparison’s reported evidence boundary.
`data.domain_details[].exited`	Whether the source exited that boundary; this does not mean it vanished from the internet.

Selected response fields from IQRush Dev. Lists are shortened and project/run IDs are placeholders; this is not the full response.

If the result is unavailable

Check HTTP status and the response’s error field before using data. A successful empty response does not establish a zero value. Preserve not_available, not_available_reason, unavailable_reason, and linked where returned. Errors and recovery shows observed examples.
