getreadystack/cms-0057-api-gate repository overview

⁠CMS-0057 API Gate

14 rules read a FHIR CapabilityStatement against CMS-0057-F. A 2021 payer statement returned 6 blocking gaps - three of the four APIs missing - and 107 days left to 1 January 2027.

⁠Run

docker run --rm -v "$PWD":/work getreadystack/cms-0057-api-gate /work/file

The same 14 rules as the VS Code extension, in a container. Mount a folder on /work.

⁠Free

• Open any FHIR CapabilityStatement and see every CMS-0057-F gap in the editor: all 14 rules, each with its API name and the days left to 1 January 2027. The sample 2021 payer statement returns 10 findings, 6 of them blocking gaps.
• --rules lists every rule

⁠With a licence ($29 once)

• Export the same audit as a dated Markdown and CSV gap report, one row per gap with its CMS-0057-F citation, so the evidence leaves the editor and goes into the compliance file an auditor asks for.

docker run --rm -e READYSTACK_LICENSE=<key> -v "$PWD":/work getreadystack/cms-0057-api-gate --dir /work --ci

A payer interoperability readiness review from an interop consultancy is commonly quoted as a five-figure engagement.
