List Regulation Wikis

GET /api/v1/regulation-wikis

Each wiki is a one-call compliance playbook — a synthesized cross-authority answer with inline citations back to the underlying regulations. This endpoint returns a paginated list of WikiSummary Objects from MidLyr’s catalog.

Use this endpoint to discover which wikis exist and find the slug you need before calling Get Regulation Wiki to retrieve the full playbook body.

Query Parameters

Name	Type	Default	Description
`domain`	string	—	Compliance domain slug. Pass an unknown value to receive a 400 with the current valid set. The full list of supported domains is enumerated below.
`query`	string	—	Free-text search over wiki `title` and `description`. When omitted, results are ordered by `updatedAt DESC`.
`updatedSince`	string	—	ISO 8601 UTC timestamp. Return only wikis updated at or after this time.
`limit`	integer	`20`	Max results per page. Min `1`, max `100`.
`cursor`	string	—	Opaque cursor from a prior response using the same query/filter set.

All parameters are optional. Calling GET /api/v1/regulation-wikis with no parameters returns the most recently updated wikis across all domains.

Pagination

Pagination is cursor-based.
pagination.nextCursor is opaque and must be reused only with the same query/filter set.
Cursors expire after 1 hour. If a cursor is invalid or expired, the API returns 400 invalid_cursor — restart from the first page.
Pagination ends when pagination.hasMore is false. Do not request another page after receiving hasMore: false.
pagination.approximateTotal is a best-effort count, suitable for scope estimates but not billing or compliance calculations.

Rate Limits

Regulation Wikis endpoints use a separate rate-limit bucket from the Regulations API. See Errors for rate-limit error shapes.

Authentication

Pass either a Bearer token or an x-api-key header — the same credentials used for /regulations. See Authentication.
