How this service works
Private ordered list/queue for an agent: push/pop/peek/range/length/clear, scoped to the paying wallet. For task queues, event logs, buffers.
Output
Returns a JSON response containing the operation result — the pushed/popped/peeked value, a list of items for range queries, an integer for length, or a success confirmation for clear/push operations. Includes the current list length where applicable.
Example use cases
Task queue for agent pipeline
“Add 'process_invoice_#4521' to the tail of my 'invoice_queue' list, then tell me how many items are now in the queue.”
Peek next event without consuming it
“Peek at the head of my 'event_log' list so I can see what the next event is without removing it from the queue.”
Drain and review a buffer
“Give me the first 50 items from my 'error_buffer' list starting at index 0, then clear the list so it's ready for new entries.”

Endpoint
POSThttps://agentbit.app/v1/memory/list?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs a persistent, ordered data structure (queue, stack, or list) that survives between invocations and is scoped to a specific wallet identity. Ideal for task queues, event buffers, breadcrumb logs, and any workflow requiring FIFO or LIFO ordering. Prefer over key-value storage when order and position matter.
Side effects
- Invalid operation enum value returns a 400 error
- Missing required 'key' or 'operation' fields returns a validation error
- Expired TTL causes list to be unavailable
- Attempting to pop from an empty list returns null or empty response
- Payment failure (x402) blocks the operation
- TTL exceeding 90-day maximum is rejected
