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: includes receiptId, txHash (Base blockchain), agentId, key, tier ('6h'), ttlSeconds (21600), paidAt, expiresAt, amount in USDC microdollars, network (eip155:8453), and service identifier.
Example use cases
Multi-step agent task handoff
“Store the current task plan as JSON under key 'task-plan' for agent ID 'planner-7' so the next step can pick it up — it only needs to live for 6 hours, go ahead and pay the write fee.”
Ephemeral scratchpad for research agent
“Write my running research notes — 'Found 3 relevant papers so far, still checking citations' — into working memory under key 'research-notes' for agent 'researcher-42', with a 6-hour expiry.”
Cross-agent state sharing
“Persist the output JSON from the data-collection step under key 'collected-data' for agent 'pipeline-agent-9' so the analysis agent can read it within the next 6 hours; pay with USDC on Base.”
Technical details
Endpoint
GEThttps://memwry.servitor.workers.dev/mem/%7BagentId%7D/%7Bkey%7D/6hWhen to prefer
Choose this endpoint when an autonomous agent needs ephemeral, sub-cent key-value storage without any account setup, and is already operating in an x402/Base USDC payment environment. Ideal for multi-step pipelines where intermediate state must survive for a few hours but permanent storage is unnecessary. Prefer over traditional KV stores when zero-setup, pay-per-use micropayment billing is required and the agent can self-fund writes on Base.
Side effects
- Payment failure: insufficient USDC balance or x402 payment rejected — write not stored
- Payload too large: body exceeds 512KB limit — rejected with error
- Invalid agentId or key path parameters — 400 error
- Network/blockchain congestion delaying settlement — write may time out
- Expired or duplicate payment nonce — transaction rejected
