How this service works
Pay-per-write working memory for autonomous agents. Sub-cent ephemeral state, zero account setup, settled instantly on Base via x402. Writes cost USDC. Reads are always free.
Output
Returns a JSON receipt confirming the write, including: receiptId, txHash (Base blockchain transaction), agentId, key, TTL tier ('12h'), ttlSeconds (43200), paidAt timestamp, expiresAt timestamp, amount paid in USDC units, network (eip155:8453), currency (USDC), and service name ('memwry').
Example use cases
Multi-step agent task handoff
“Save the current task progress — 'step 2 of 5 complete, awaiting user confirmation' — under the key 'task_progress' for agent 'pipeline-agent-77' in Memwry's 12-hour working memory so the next step can pick it up.”
Ephemeral goal state for autonomous agent
“Write my agent's current goal — 'find cheapest flight to NYC before noon' — under the key 'active_goal' for agent-id 'flight-scout-01' in Memwry, using the 12-hour tier so it expires automatically after the session.”
Cheap per-run scratch pad for agent loop
“Store the intermediate search result count '42 matches' under the key 'search_count' for agent 'scraper-agent-9' in Memwry's 12h working memory — I don't want to pay for a full database just for this run.”
Technical details
Endpoint
POSThttps://memwry.servitor.workers.dev/mem/12h/%7BagentId%7D/%7Bkey%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs cheap, throwaway, short-lived key-value state (12-hour TTL) without any account setup, user login, or long-term commitment. Ideal for autonomous agent pipelines on Base where you want sub-cent-scale costs, instant settlement via x402 USDC micropayment, and automatic expiry — as opposed to a traditional database (no signup required), Redis (no infra to manage), or longer-lived memory tiers (use a 24h or 7d tier if the data needs to outlast 12 hours).
Side effects
- Payment insufficient or rejected by x402 facilitator — write not committed
- Invalid or missing agentId/key path parameters — 400 error
- USDC wallet has insufficient funds — payment fails, no write occurs
- Network congestion on Base causing settlement delay
- Key collision if same agentId+key written twice — behavior may overwrite or reject depending on service logic
- Cloudflare Worker timeout — ephemeral infrastructure failure
