The status page needs JavaScript, an app must be registered and consented to by a person, and the JavaScript client on npm lacks a token-leak fix merged in June 2026.\n\n## Before you call either\n\n### Backblaze B2\n\n1. Take the region from the key's S3 endpoint (the second label of s3.\u003cregion\u003e.backblazeb2.com) and pass it as the SDK region\n2. Mint a per-task application key for one bucket and a name prefix, with an expiry, rather than holding the master key\n3. Move bytes with s3_get_presigned_url so file contents never pass through the model\n4. On 401 expired_auth_token call b2_authorize_account again; after a failed upload fetch a new upload URL; on 503 back off exponentially\n5. Expect fewer than 40 tools with a non-master or read-only key; that's the server trimming tools to the key\n\n### OneDrive and SharePoint files (Microsoft Graph)\n\n1. Use PUT `/content` only up to 250 MB. Above 10 MiB Microsoft advises `createUploadSession`, with fragments in multiples of 320 KiB and under 60 MiB each\n2. Send the bearer token on the `createUploadSession` POST only. The PUT calls to `uploadUrl` can return 401 if an `Authorization` header is included\n3. Set `expirationDateTime` and `scope` on `createLink`. Without a scope the tenant's default link type is created, which may be wider than intended\n4. Follow the 302 from GET `/content` straight away. Pre-authenticated download URLs can expire within minutes and need no `Authorization` header\n5. Wait for `Retry-After` on 429 and 503. Throttled requests still count against the limits, and continued overuse can get the app blocked\n\n## Questions\n\n### Which is better for AI agents, Backblaze B2 or OneDrive and SharePoint files (Microsoft Graph)?\n\nBackblaze B2 scores 75.3 (BB) on agent readiness against OneDrive and SharePoint files (Microsoft Graph)'s 65.3 (B), and leads in 4 of 7 scored categories.\n\n### Do Backblaze B2 and OneDrive and SharePoint files (Microsoft Graph) need an API key?\n\nBackblaze B2 needs an API key. OneDrive and SharePoint files (Microsoft Graph) uses an OAuth sign-in.\n\n### Can an agent call Backblaze B2 and OneDrive and SharePoint files (Microsoft Graph) without installing anything?\n\nYes. Backblaze B2 has a hosted endpoint at https://s3.us-west-004.backblazeb2.com and OneDrive and SharePoint files (Microsoft Graph) at https://graph.microsoft.com/v1.0.\n\n### Are Backblaze B2 and OneDrive and SharePoint files (Microsoft Graph) open source?\n\nBackblaze B2 is open source (MIT). No open-source release is listed for OneDrive and SharePoint files (Microsoft Graph).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/backblaze-b2-vs-onedrive-sharepoint.json, and with the fewest tokens: https://www.anchorterminal.com/compare/backblaze-b2-vs-onedrive-sharepoint.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"backblaze-b2\", \"b\": \"onedrive-sharepoint\"}`.
