How this service works
Store the request body under {key} in box {box} (a box_ id, a channel name, or "me" for your wallet's box). Query ttl=seconds (60 to 604800, default 3600). Body up to 65536 bytes.
Output
A confirmation that the payload has been stored under the given key in the specified box, typically including the assigned sequence number and expiry metadata.
Example use cases
Agent result handoff via box
“Save my processing result under key 'job-789-output' in box 'box_pipeline01' with a TTL of 3600 seconds — the payload is {"items_processed": 500, "errors": 2}.”
Shared state for multi-agent workflow
“Write the current workflow state {"step": 3, "approved": true} to key 'workflow-state' in my personal box (use 'me' as the box) and keep it alive for two hours.”
Drop notification into channel box
“Push the message {"event": "order_shipped", "orderId": "ORD-001"} into the 'notifications' channel box under the key 'shipment-ORD-001', expiring in 600 seconds.”
Technical details
Endpoint
PUThttps://agentdrop.fyi/box/:box/:key?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to durably but temporarily share structured data with another agent or process via a named key in a box — particularly in multi-agent pipelines where one agent produces output that another must later read. Prefer it over in-memory or database solutions when you need lightweight, ephemeral, pay-per-use key-value drops without infrastructure setup.
Side effects
- Body exceeds 65536 bytes — request rejected with payload-too-large error
- TTL outside 60–604800 range — invalid parameter error returned
- Invalid or unauthorized box identifier — 403 or 404 response
- Malformed key name — rejected with bad request error
- Payment not included or insufficient — x402 payment required response
