Skills
get_memory

Retrieve a stored value by namespace and key.

put_memory

Store a value with optional tags, priority, and storage duration in months (default 1). value_json must be ≤ 1 MB. On overwrite, the existing expiry is scaled by the KB size ratio of old to new value.

delete_memory

Delete a stored value.

list_keys

List keys in a namespace with metadata (created_at, updated_at, updated_count, ttl, priority, last_modified_key_id). Returns up to 1000 keys sorted by recency. Expired keys are automatically excluded.

top_memories

Return the top N highest-priority non-expired keys in a namespace, ordered by priority descending. Useful for loading the most important context when space is limited. Maximum n is 1000.

list_namespaces

List all namespaces for this account.

search_by_tag

Find (namespace, key) pairs with a given tag. Returns up to 1000 results.

get_account

Get account status, credit balance, and available credits.

list_api_keys

List all API keys on this account.

create_api_key

Create a new live API key. Only available for active accounts. The key is shown once — store it immediately.

revoke_api_key

Revoke an API key by ID. The key stops working immediately.

list_payments

List payment history for this account.

settle_balance

Charges the saved payment method to settle your outstanding balance. Requires explicit user approval before running. For trial accounts, returns the activation URL instead. Minimum charge: $5.

submit_exit_feedback

Submit feedback when a trial ends without activation. Free to call — no credits charged. Only the first submission per account is recorded; duplicates are silently ignored. Call this when the user declines to activate or the trial is exhausted.

submit_feature_request

Submit a feature request or product feedback. Charged at storage rate: ceil_kb(description_length) × 100 credits per KB. Available to trial and active accounts alike.
