Chapter scores C+ on Supergood's API Report Card. No public API. Chapter's observable partner surface is an embedded iframe widget on switchers.askchapter.org plus co-branded landing pages, with partnerships run as a business development funnel. No portal, docs, sandbox, webhooks, or SDK exist for partners or consumers.
Chapter has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Chapter is a New York-headquartered Medicare advisory company that operates as a licensed health insurance agency (Chapter Advisory, LLC) and a data-and-technology-enabled plan-selection platform.
Healthcare, Medicare advisor / plan-selection and enrollment platform with a secondary B2B partner-distribution layer. Consumer flow: a Medicare-eligible prospect lands on askchapter.org (or on a partner-embedded iframe at switchers.askchapter.org/ntm/<partner>/simple-switchers, e.g., the AOL co-brand at switchers.askchapter.org/ntm/aol/simple-switchers), enters ZIP, current coverage, prescription list, preferred providers, and plan priorities, and either uses the self-service comparison tool or books a phone/video appointment with a Chapter-employed licensed advisor.
Chapter is a privately held, venture-backed Series C company.
Mixed. Chapter does not hold the bound Medicare policy of record, that lives with the underlying carrier (UnitedHealthcare, Humana, Aetna, Cigna, Elevance/Anthem, Centene, Kaiser, BCBS plans, etc.).
Founded 2020 in New York, NY by Cobi Blumenfeld-Gantz (CEO, ex-Google product manager and former senior aide to JD Vance), Vivian Lee (Chief Health Officer, former president of Verily Health Platforms and former CEO of University of Utah Health Care), and Michael Greenspon (COO).
No public developer portal, no documentation, no sandbox, no SDK, partners and third-party developers cannot evaluate any Chapter API surface without first signing a partnership agreement. Embedded iframe widget (switchers.askchapter.org/ntm/<partner>/simple-switchers) is a UI embed, not an API, partner sites do not have programmatic access to lead data, advisor-assignment events, conversion outcomes, or recommendation outputs generated inside their own embed.

Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official Chapter MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Chapter doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
