This page lists every external data source Vertix consumes through a verified code integration today. It is the single source of truth for our license obligations and attribution requirements. The list is regenerated automatically once per day from compliance.providers in the Vertix Postgres database, against the canonical JSON in marketing/nextjs/src/lib/connected-apis.json.
A source only appears here when an actual file in tools/ or marketing/nextjs/src/executes a programmatic call to its API or processes its bulk download. Discussed-but-not-installed providers do not appear. Roadmap is documented separately in /disclosures.
Refresh policy
- Cron: daily at random hour (0–18h offset from a fixed launchd trigger), via
tools/automation/connected_apis_refresh.py. - Detection of new sources: when a new entry appears in the canonical JSON, the cron flags it for human review of the provider's Terms of Service before publishing here.
- Audit changelog: every change (add, remove, license update, status change) writes a row to
compliance.provider_changeswith timestamp, actor and rationale, retained immutably for compliance review. - Last refresh:
2026-05-06T06:34:23ZUTC.

What is NOT a data source
The Vertix reasoning stack runs entirely on local open-source models when processing any patient-protected health information (PHI). Cloud inference providers (Anthropic, OpenAI, Google, AWS Bedrock) are not in the production data flow for PHI and therefore do not appear in this registry. Their use is restricted to non-PHI development and research tooling, documented separately.
