Marketplace API (BYOK) lets an AI assistant read your own Marketplace API data through the Marketplace API API with a key you supply (Marketplace API key). Read-only: 10 tools (get_market_years, list_counties_by_zip, list_issuers, get_issuer, search_plans, get_plan, get_lowest_cost_silver_plan, get_second_lowest_cost_silver_plan, search_drugs, get_poverty_level_percent). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to marketplace.api.healthcare.gov. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Marketplace API. Marketplace API and its logos are trademarks of their owners and are used only to say which service the connector works with.
Sources: Live from the Marketplace API API (marketplace.api.healthcare.gov) with a BYOK key; documentation: https://developer.cms.gov/marketplace-api/api-spec. Endpoints checked against that documentation on 2026-10-16.
