How this service works
Reserve TTL object slot
Output
Returns a reserved object slot descriptor including an upload endpoint or presigned URL, an object ID, the allocated TTL expiration time, the maximum byte limit, and the accepted content type — enabling the caller to upload data to the slot immediately.
Example use cases
Agent pipeline intermediate artifact cache
“I need to store a 10MB CSV file between two steps in my agent pipeline — reserve a slot that expires in 4 hours so the downstream agent can fetch it.”
Short-lived image upload buffer
“Reserve a 50MB storage slot that auto-deletes in 24 hours for uploading a generated PNG image — it's temporary output an agent needs to share before it expires.”
Long-running batch result staging
“Allocate a 100MB storage slot with a content type of application/octet-stream that lasts 30 days so my batch job can deposit its final output and another agent can retrieve it later.”
Technical details
Endpoint
POSThttps://stash.fluidrack.com/v1/objectsWhen to prefer
Choose this endpoint when an AI agent needs lightweight, pay-per-use, TTL-bound temporary object storage without managing S3 credentials directly — especially suited for agent-to-agent artifact handoff, pipeline staging, or ephemeral output buffering. Prefer over general-purpose S3 when auto-expiry, per-call billing via x402, and minimal setup are priorities.
Side effects
- ttlSeconds below minimum of 3600 returns validation error
- ttlSeconds above maximum of 2592000 (30 days) returns validation error
- maxBytes exceeds 100,000,000 byte ceiling returns 400
- payment of $0.01 USDC not provided or invalid returns 402
- malformed contentType string may cause slot creation failure
- slot not used before expiry results in automatic deletion with no data retained
