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
A confirmation that the value was written to the specified agentId/key slot in ephemeral working memory, settled instantly on Base with USDC via x402. Reads of the same key are subsequently free.
Example use cases
Checkpoint state mid-pipeline
“Save the current extraction result under key 'last_scraped_url' for agent 'crawler-01' so the next step can pick up where it left off.”
Track task completion across steps
“Write 'done' to the 'phase2_status' key for agent 'orchestrator-42' so downstream agents know phase 2 finished successfully.”
Store intermediate LLM output
“Save the summary text the LLM just produced under key 'summary_draft' for agent 'writer-bot-99' so I can retrieve it in the next pipeline stage.”

Endpoint
POSThttps://memwry.servitor.workers.dev/mem/%7BagentId%7D/%7Bkey%7DWhen to prefer
Choose Memwry when you need ultra-low-cost (sub-cent), zero-setup ephemeral state for autonomous agents and you are already operating in a crypto-native / x402 micropayment environment on Base. It is ideal for agentic pipelines that need to pass small blobs of state between steps without provisioning a database or managing accounts. Prefer alternatives if you need persistent long-term storage, SQL queries, vector search, or if your stack does not support x402 payment headers.
Side effects
- Insufficient USDC balance or x402 payment failure — write rejected
- Invalid agentId or key path parameters — 400 or routing error
- Expired ephemeral state — key may no longer exist on subsequent read
- Network timeout on Cloudflare Worker — transient 5xx error
- Malformed request body — schema validation failure
