Changelog

Notable, user-visible changes to the Filedgr API.

August 2026

Added POST /credentials/api-keys in the web app — generate an API key from your account. The plaintext secret is returned once and is not recoverable.
Changed Subscriptions can now be cancelled and updated, and carry an explicit end date.
Changed On renewal the credit balance is replaced with the period allowance rather than added to it, so unused credits do not roll over. An annual payment sets twelve times the monthly allowance up front.
Removed is_headless from vault create and update request bodies.

Added Vault permission routes on the partner API — POST, GET and DELETE /vaults/{vault_id}/permissions. A backend integration can now share a vault it created; previously that needed an interactive web session.
Added Machine-API parity with the web app: notifications, statistics, assets, signatures, plans, subscriptions, retries and app config.
Added Proof Packages — POST /proof-packages, GET /me/proof-packages, POST /me/proof-packages/{id}/download and POST /me/proof-packages/{id}/extend.
Removed The shares module, superseded by Proof Packages.
Changed Data attachments are limited to 50 files.

Added A synchronous credit pre-flight check. Creating a vault, stream or data attachment now returns 402 InsufficientCreditsError immediately — with required, balance and has_subscription — instead of the resource failing asynchronously.
Added Cursor pagination (limit, cursor, next_cursor) for /me/proof-packages.
Added Ledger alias normalisation on input (amoy, polygon, zkevm, …). Responses always carry the canonical value.
Added Push notifications (FCM) as a notification channel.

Added Off-chain asset permissions.
Added Plans, products and plan features behind GET /plans and GET /plans/{plan_id}.
