Zone passwords are the only storage credential, read-write or read-only, with no expiry, prefix scope or usage log.\n\n## Before you call either\n\n### Azure Blob Storage\n\n1. Request an Entra ID token for https://storage.azure.com/ and send it as a Bearer header with `x-ms-version` and `x-ms-date`. Put Blob also needs `x-ms-blob-type: BlockBlob`\n2. Ask for a Storage Blob Data role on the one container. Role changes can take up to 10 minutes to apply\n3. To share a file, call Get User Delegation Key, then sign a SAS with `sp=r`, `spr=https` and a short expiry. Treat the URL as a secret\n4. Send `If-None-Match: *` on Put Blob so a retry can't overwrite a blob another call wrote\n5. On 503 ServerBusy back off exponentially. After 500 OperationTimedOut check the blob's state before retrying, since the write may have succeeded\n\n### Bunny Storage\n\n1. Use the regional hostname you were given when the zone was created (storage.bunnycdn.com is Frankfurt). Other regions return a 401\n2. Send the body as raw bytes with --data-binary. Base64 or form encoding gets a 401\n3. Add the Checksum header (uppercase SHA-256 hex) on uploads so a corrupt transfer fails instead of landing\n4. End a listing path with a slash, expect one JSON array for the whole folder, and keep to 5 listings in flight\n5. On a SlowDown 503 from the S3 endpoint wait the Retry-After seconds, then back off exponentially\n\n## Questions\n\n### Which is better for AI agents, Azure Blob Storage or Bunny Storage?\n\nAzure Blob Storage scores 75.7 (BB) on agent readiness against Bunny Storage's 58.3 (C), and leads in 6 of 7 scored categories. Bunny Storage leads on payments \u0026 pricing.\n\n### Do Azure Blob Storage and Bunny Storage need an API key?\n\nAzure Blob Storage takes an API key or an OAuth sign-in. Bunny Storage needs an API key.\n\n### Can an agent call Azure Blob Storage and Bunny Storage without installing anything?\n\nYes.
