Get Regulation Wiki

GET /api/v1/regulation-wikis/:slug

Each wiki is a one-call compliance playbook — a synthesized cross-authority answer structured in Authority Chain format (Statute → Regulation → Examination Handbook) with inline citations back to the underlying regulations. This endpoint returns the full Wiki Object for a single activity, including the synthesized body and the sources array of externalId slugs.

Parameters

Name	In	Type	Description
slug	path	string	Activity slug from a List Regulation Wikis result (e.g. sar-filing)

Worked Example: SAR Filing

Fetch the SAR filing playbook:

curl "https://api.midlyr.com/api/v1/regulation-wikis/sar-filing" \
  -H "x-api-key: $MIDLYR_API_KEY"

Resolve the primary statutory source to read verbatim text:

curl "https://api.midlyr.com/api/v1/regulations/us-code-31-5318" \
  -H "x-api-key: $MIDLYR_API_KEY"

Resolve the primary regulatory source and pull its content:

# 1. Get document metadata and total size
curl "https://api.midlyr.com/api/v1/regulations/31-cfr-1020-320" \
  -H "x-api-key: $MIDLYR_API_KEY"

# 2. Read the full document body
curl "https://api.midlyr.com/api/v1/regulations/31-cfr-1020-320/content?offset=0&limit=40000" \
  -H "x-api-key: $MIDLYR_API_KEY"

Resolving Sources

Each entry in sources[] is an externalId slug that resolves to a regulation document in the Regulations API. Use Get Regulation Details with the slug as the document id.

Sources are ordered from most authoritative (statute) to most operational (examination guidance), mirroring the section order in body.

Not Found

If the slug does not exist, the API returns 404 not_found. Slugs are stable and never reassigned — a 404 means the wiki has not been published yet or the slug is misspelled.

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. See Authentication.
