## Which one, for what

### Bunny Storage (C)

Good for: An agent that publishes files to be served through a CDN at the lowest price and doesn't need fine-grained credentials.

Ahead on:
- Reliability, 75 against 65
- Schema & documentation, 64 against 59
- Maintenance & community, 63 against 46

Watch for: Zone passwords are the only storage credential, read-write or read-only, with no expiry, prefix scope or usage log

### Wasabi Hot Cloud Storage (C)

Good for: Backup, archive and media libraries of a terabyte or more that are written once and read moderately, where flat pricing and Object Lock matter.

Ahead on:
- Agent ergonomics, 68 against 57
- Security & auth, 83 against 45
- Transparency & trust, 69 against 60

Watch for: No numeric request limits for the S3 API. The fair use policy adjusts concurrent requests per account by stored volume

## Verdicts

**Bunny Storage.** $0.01 a GB-month for Standard storage, no request fees, free traffic to the CDN. Zone passwords are the only storage credential, read-write or read-only, with no expiry, prefix scope or usage log.

**Wasabi Hot Cloud Storage.** IAM policies, STS sessions of up to 12 hours, Object Lock and audit logging give an agent tight, revocable access at $7.99 a TB-month with no egress or request fees. No request limits are published with numbers for the S3 API, there is no OpenAPI file, and billing assumes 1 TB and 90 days of storage as minimums.

## Before you call either

### Bunny Storage

1. Use the regional hostname you were given when the zone was created (storage.bunnycdn.com is Frankfurt). Other regions return a 401
2. Send the body as raw bytes with --data-binary. Base64 or form encoding gets a 401
3. Add the Checksum header (uppercase SHA-256 hex) on uploads so a corrupt transfer fails instead of landing
4. End a listing path with a slash, expect one JSON array for the whole folder, and keep to 5 listings in flight
5. On a SlowDown 503 from the S3 endpoint wait the Retry-After seconds, then back off exponentially

### Wasabi Hot Cloud Storage

1. Use the bucket's own regional endpoint, such as `s3.eu-central-2.wasabisys.com`. The docs say a wrong endpoint allows GET but not PUT or DELETE
2. Ask for a sub-user key with a policy limited to one bucket, or an STS session. A root key has full access, billing included
3. Avoid short-lived objects. Each object deleted before 90 days is billed for the remaining days, and objects under 4 KB bill as 4 KB
4. Keep monthly downloads at or below the stored volume, the limit of the free egress policy
5. Call `https://` endpoints explicitly. The S3 API also accepts plain HTTP
6. For the MCP beta, type `https://mcp.wasabisys.dev/s3` from the page text. The links in the docs table point at a different host
