How this service works
Agent memory, list keys. List up to 100 keys saved in your namespace, optionally only those starting with a prefix, with their size, save time and expiry; pass the returned cursor for the next page. Values are not included (read them with /memory/get). Values are kept until they expire (at most 30 days) or are deleted; reads anywhere may lag a write made elsewhere by up to a minute. Use to see what an agent has saved.
Output
Returns a JSON object containing an array of key entries (each with key name, size in bytes, updatedAt timestamp, and expiresAt timestamp), the total count of matched keys, and a cursor string for fetching the next page. Values themselves are not included — use /memory/get to retrieve them.
Example use cases
Audit saved agent state
“List all the keys stored in my agent's memory namespace 'workflow-agent-abc123xyz789def0' so I can see what it has remembered from previous sessions.”
Browse paginated memory namespace
“My agent has a lot of saved data in namespace 'pipeline-state-q1r2s3t4u5v6w7x8' — fetch the next page of keys using cursor 'eyJrZXkiOiJ0YXNrLTEifQ' so I can keep scrolling through what's stored.”
Find task-related memory keys
“In namespace 'research-bot-secret-abc123def456gh78', list only the keys that start with 'report-' so I can see which reports my agent has cached.”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/memory/list?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover or audit what it has previously stored in a namespace, navigate large sets of saved data via pagination, or filter stored keys by a known prefix before fetching specific values. Prefer this over /memory/get when you don't yet know which exact keys exist or want a summary view (sizes, expiry) without loading values. It is the right starting point for any inspection or cleanup workflow over agent-persisted state.
Side effects
- Missing or invalid namespace returns an error (namespace must be 16–128 alphanumeric/-/_ characters)
- Namespace not found or empty returns keys: [] with count: 0
- Invalid cursor string causes pagination to fail or restart from the beginning
- Prefix filter with no matches returns empty keys array
- Eventual consistency lag: a key written recently elsewhere may not appear for up to 60 seconds
- Rate limiting or payment failure returns 402 if credits are exhausted
