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 (UUID), txHash (Base L2 transaction hash), agentId, key, tier ('6h'), ttlSeconds (21600), paidAt and expiresAt timestamps, USDC amount charged (in micro-units), network ('eip155:8453'), currency ('USDC'), and service name ('memwry').

Example use cases

Agent scratchpad for multi-step task

“Save the key 'scratchpad' with my current plan under agent ID 'planner-agent-7' in Memwry's 6-hour working memory so I can retrieve it later in this session.”

Caching intermediate reasoning state

“Write the key 'intermediate-result' for agent 'researcher-42' into Memwry's ephemeral memory — it only needs to live for 6 hours while the research job is running.”

Storing agent goal across tool calls

“Persist the key 'current-goal' for agent ID 'executor-001' in Memwry's 6-hour memory tier so the agent can reference its objective across multiple tool calls without losing state.”

When to prefer

Choose this endpoint when an AI agent needs ultra-cheap, ephemeral key-value state that expires automatically in 6 hours with no account setup, billed per write via x402 on Base. Ideal for autonomous agent workflows where state only needs to persist for a single session or task window. Prefer over traditional databases when you want zero infrastructure overhead and instant crypto settlement at sub-cent cost.

Side effects

Payment insufficient or missing — x402 payment header not attached or USDC balance too low
Invalid agentId or key format — may return 400 Bad Request
Write conflict if key already exists and overwrite not supported — may return 409
Network congestion on Base causing settlement delay — rare but possible
TTL already elapsed before read — state expires exactly 6 hours after write
Malformed request body — returns 400 with validation error
