Fireblocks is retiring the GET /v1/vault/accounts API endpoint on December 31st, 2026. If your workspace calls this endpoint, update your integration to use GET /v1/vault/accounts_paged before that date. After the retirement date, GET /v1/vault/accounts will stop returning data.

Why we are retiring it

GET /v1/vault/accounts returns every vault account in a workspace in a single response. This gets slow as a workspace grows, and the endpoint does not support filtering or sorting.

What to use instead

The Get paginated vault accounts endpoint (GET /v1/vault/accounts_paged) returns the same vault account data, plus tags, customerRefId, and autoFuel. Results come back in an accounts array alongside a paging object with before/after cursors and nextUrl/previousUrl links, so you do not need to build your own offset logic. You can also filter by tag inclusion or exclusion, minimum balance, asset, and name prefix or suffix. These filters are not available on Get vault accounts, the endpoint being retired.

Timeline

Fireblocks first announced this deprecation in 2023. December 31st, 2026 is the final retirement date.
