How this service works
Store a value under a key. Costs $0.002. Values up to 64 KB, kept for ttl_seconds (default 3600, max 604800). The write becomes visible once the payment has settled.
Output
A confirmation that the write was accepted and will become visible once the $0.002 USDC micropayment has settled; typically includes acknowledgment of the key, box, and TTL applied.
Example use cases
Cross-agent secret handoff
“Write the API key 'sk-live-9xZ...' under the key 'api_key_handoff' in channel box 'agent-relay', and keep it there for 1800 seconds so the other agent can pick it up.”
Ephemeral config drop for workflow
“Save this JSON config blob under the key 'pipeline_config_v2' in my personal box for 3600 seconds — I'll have the downstream step read it back shortly.”
Temporary result parking
“Drop the text summary I just generated under the key 'summary_result_42' in box 'box_reports' and keep it for 24 hours so the review agent can retrieve it later.”
Technical details
Endpoint
POSThttps://dead-drop.chris15118-4cd.workers.dev/mcp?utm_source=zero.xyz#putWhen to prefer
Choose this endpoint when an AI agent needs to temporarily park a value (up to 64 KB) under a named key for another agent or process to retrieve later, especially in micropayment-gated (x402) agentic workflows where ephemeral cross-agent data sharing is required and data does not need to outlast the configured TTL.
Side effects
- Payment not settled — write remains invisible until payment clears
- Value exceeds 64 KB limit — request rejected
- TTL exceeds 604800 seconds (7 days) — capped or rejected
- Invalid or missing key/box identifier — bad request error
- Cloudflare Worker timeout or downstream error — 5xx response
