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### Amazon S3\n\n1. Hold STS session credentials scoped by a session policy, never a long-lived IAM user key\n2. Sign presigned URLs with credentials that outlive the URL; a URL signed with a one-hour session token dies with the token\n3. Send If-None-Match with * on PutObject so a retry can't overwrite a file another call wrote\n4. Track the Free plan's end date on a new account; when the plan expires AWS suspends the account and access to the stored objects\n5. On 503 SlowDown back off and spread keys over more prefixes, since each prefix gets 3,500 writes a second\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, Amazon S3 or OneDrive and SharePoint files (Microsoft Graph)?\n\nAmazon S3 scores 77.9 (BB) on agent readiness against OneDrive and SharePoint files (Microsoft Graph)'s 65.3 (B), and leads in 6 of 7 scored categories.\n\n### Do Amazon S3 and OneDrive and SharePoint files (Microsoft Graph) need an API key?\n\nAmazon S3 needs an API key. OneDrive and SharePoint files (Microsoft Graph) uses an OAuth sign-in.\n\n### Can an agent call Amazon S3 and OneDrive and SharePoint files (Microsoft Graph) without installing anything?\n\nYes. Amazon S3 has a hosted endpoint at https://s3.us-east-1.amazonaws.com and OneDrive and SharePoint files (Microsoft Graph) at https://graph.microsoft.com/v1.0.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/amazon-s3-vs-onedrive-sharepoint.json, and with the fewest tokens: https://www.anchorterminal.com/compare/amazon-s3-vs-onedrive-sharepoint.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"amazon-s3\", \"b\": \"onedrive-sharepoint\"}`.
