The Regulation Wiki Object

Regulation wiki objects represent MidLyr’s synthesized compliance playbooks — one per compliance activity (e.g. sar-filing, ctr-filing). Each wiki distills requirements from multiple authoritative sources into a single cross-authority synthesis with inline citations back to the underlying regulations.

Two shapes are returned depending on the endpoint:

WikiSummary Object

Wiki Object

Section titled “Wiki Object”

The full wiki object is a superset of WikiSummary. It adds sources and body.

Fields

Section titled “Fields”

All WikiSummary fields, plus:

FieldTypeDescription
sourcesstring[]Ordered list of externalId slugs for the regulations synthesized into this wiki. Each slug resolves to a full regulation document via Get Regulation Details using the externalId lookup path.
bodystringMarkdown playbook synthesized in canonical “Authority Chain” format. Sections flow Statute → Regulation → Examination Handbook, with inline citations.

The sources Array

Section titled “The sources Array”

Each entry in sources[] is an externalId slug. Resolve any entry to a full regulation document:

Terminal window
curl "https://api.midlyr.com/api/v1/regulations/31-cfr-1020-320" \
  -H "x-api-key: $MIDLYR_API_KEY"

Sources are ordered from most authoritative (statute) to most operational (examination guidance). The ordering mirrors the Authority Chain structure of body.

Body Format

Section titled “Body Format”

body is a UTF-8 markdown string. It follows the Authority Chain structure:

  1. Statute — the enabling law with U.S. Code citation
  2. Regulation — CFR sections implementing the statute
  3. Examination Handbook — agency examination guidance operationalizing the regulation

Inline citations appear as [Source: <externalId>] anchors throughout the text. Section headings use standard ATX markdown (##, ###).
