How this service works
Private key/value memory for an agent: remember values across calls (set/get/delete/list/exists), scoped to the paying wallet.
Output
Returns a JSON object containing the operation result: for 'get', the stored value; for 'exists', a boolean; for 'list', an array of keys up to the specified limit; for 'set' and 'delete', a confirmation of success. Data is scoped to the paying wallet.
Example use cases
Persist user preferences across sessions
“Remember that the user prefers Celsius temperature units — save that under the key 'temp_unit' with the value 'celsius' in the 'user_prefs' namespace so you can recall it next time.”
Cache workflow intermediate results
“Store this JSON summary under the key 'last_report_summary' in the 'reports' namespace, and make it expire in 86400 seconds so it refreshes daily.”
Check onboarding completion flag
“Check whether the key 'onboarding_complete' exists in my 'state' namespace — I need to know if the user has already finished setup before proceeding.”
Technical details
Endpoint
POSThttps://agentbit.app/v1/memory?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs lightweight persistent state or memory across calls — session flags, user preferences, cached results, or workflow checkpoints — scoped privately to the paying wallet. Prefer it over in-context memory when data must survive across sessions, and over full databases when simplicity and per-call pricing are priorities.
Side effects
- Key not found on 'get' or 'delete' returns null or 404-style result
- Missing required 'key' field for set/get/delete/exists operations returns validation error
- Missing required 'value' field for 'set' operation returns validation error
- TTL exceeding 90 days is clamped or rejected
- Invalid operation enum value returns an error
- Payment failure or insufficient balance blocks the call
