Fireblocks will retire GET /v1/vault/accounts/{vaultAccountId}/{assetId}/addresses on May 16, 2027. After that date, the endpoint will stop returning data. Update any automation or scripts that depend on it before then.
Why we're retiring it
GET /v1/vault/accounts/{vaultAccountId}/{assetId}/addresses returns every address of an asset in a vault account in one response. As the number of addresses grows, the response gets very large and slow, and requests can time out. The paginated endpoint returns the same data in smaller pages.
What to use instead
Old endpoint (being retired): GET /v1/vault/accounts/{vaultAccountId}/{assetId}/addresses
New endpoint (replacement): GET /v1/vault/accounts/{vaultAccountId}/{assetId}/addresses_paginated
The new endpoint returns the same address data. Results come back in an addresses array alongside a paging object with before and after cursors. To get the next page, pass the after cursor in your next request; use limit to set the page size. In the Fireblocks SDKs, use getVaultAccountAssetAddressesPaginated (TypeScript, Java) or get_vault_account_asset_addresses_paginated (Python).
Timeline
Fireblocks has marked this endpoint as deprecated in the API reference since 2024. May 16, 2027 is the final retirement date.
