Does SERFF have an API?

Integration services for legacy SERFF

NAIC's SERFF Product Steering Committee summary from February 25, 2026 lists three interfaces for the current, legacy system:

The same summary says all of these services will eventually be retired.

SERFF Integration Services have been around for years. The SERFF 7.10 release notes from November 2016 describe its second phase as an event-based service that lets insurance companies retrieve notifications about activity on their filings and retrieve data about those filings. As described, it concerns a company's own filings: it lets a filer bring activity on its filings into its own systems, for example to keep an internal filing tracker in step with SERFF.

APIs in the modernized SERFF

NAIC began the SERFF modernization project in March 2022. Its project page lists the goals as an improved interface, a modernized technical architecture, better data management and "an API layer to allow for easier integration with other partners and tools." States move to the new platform on a published schedule; the page lists Arizona for October 19, 2026 and Arkansas for November 23, 2026.

The February 2026 summary lists what is being built for the modernized system:

• Data API: a data pull for both states and industry.
• Transactional API: a data push, in progress for industry.
• Snowflake: data access, currently for states only.

It adds that all of these services require legal agreements with the NAIC, and gives serffmodernizationquestions@naic.org as the contact for updates. NAIC's SERFF page also links a Web Services Support Checklist for technical support requests, which lists the legacy two-way interface, the legacy one-way pull and the modernized Data API, each in a production and a beta environment.

What about public filings?

SERFF Filing Access is a web application with one site per state. NAIC says each state's site is being rebuilt as that state moves to the modernized SERFF, that the rebuilt sites currently work much like the legacy ones, and that serff.com hosts the hub linking to every state's site. Its February 2026 summary is direct about data access: "Presently, there are no services or bulk downloads for SFA data."

So a researcher works through the interface. South Carolina's department describes the flow: select Begin Search, click Accept once you have reviewed the User Agreement, then enter search criteria. Georgia's instructions add that results open filing by filing and that a filing's attachments can be selected and downloaded as a zip file.

The User Agreement and the state's own terms govern how the material may be used. Arkansas, for example, limits use of filing material viewed through its site to reviewing the information as Arkansas law requires. Read the terms you accept before relying on the material for any other purpose.

Options when you need many filings

• Search state by state, narrowly. Each state's site takes a business type plus criteria such as type of insurance, company name and date ranges, as California's instructions describe. Narrow searches return manageable result sets; see SERFF tracking numbers for looking up one filing directly.
• Ask the department. States answer records requests for filings or documents that are not online. Texas points readers to an open records request for filings not found in SERFF Filing Access, and Washington to a public disclosure request when a filing or document cannot be found or downloaded. Some states charge copying or retrieval costs.
• Use the state's own system where it has one. A few states publish filings through their own search systems instead of, or as well as, SERFF Filing Access. Are insurance rate filings public? covers the main patterns.
• For your own filings, ask NAIC. A filer that wants SERFF data about its own filings in an internal system is the audience for SERFF's integration services. Those need a legal agreement with the NAIC; the modernization contact above is the starting point.

What this means in practice

• There is no public API for SERFF Filing Access. Public filings are read through each state's site or obtained from the state. Anyone relying on a collection of public filings should ask how it was gathered, how current it is and which states it covers.
• Coverage differs by state. Each state decides what it publishes, from when and in how much detail, so a set of public filings is never uniform across states. Confidential and trade secret material is usually withheld; see confidentiality in filings.
• Integration plans should follow modernization. A filer building on the legacy interfaces should plan for their retirement and for the Data API and Transactional API that replace them.
