Provider API And Transfer Limits
Last Updated: May 25, 2026
This page combines official provider documentation with Stratofusion's current transfer-quota behavior. Where a provider does not publish a hard daily transfer limit for its public APIs, Stratofusion records usage for visibility but does not block transfers.
Stratofusion Behavior
- Transfer quota tracking is scoped to
(provider, account, user)internally. GET /api/transfer-quotasreturns account-scoped snapshots for connected Google Drive, OneDrive, Dropbox, Box, and pCloud accounts.- Stratofusion currently enforces only Google Drive's documented 750 GB upload/copy quota.
- Direct uploads, download manifests, cross-provider copy/move, and folder-sized transfer launches feed the same tracker when byte counts can be resolved.
- Streamed copy/move launch endpoints support larger logical batches subject to subscription, provider, and quota limits. Legacy JSON rclone endpoints and the Fly gateway still keep a 50 operations per request safety cap.
- For providers without a documented daily API quota, the tracker uses an app-local UTC daily window for consistent internal accounting.
- API request budgets are not exposed as a user-facing dashboard; users are notified only when operations are actually throttled.
