How this service works
Give an AI agent a credit account. Set a limit and a spending policy, and the agent makes approved, metered purchases from providers that accept Vaaya.
Output
Returns a list of matching memory entries (nodes, edges, or episodes) from the user's Zep memory graph that are semantically relevant to the provided query, based on the selected scope.
Example use cases
Recall user preferences for personalization
“Search Zep memory for user 'user_42' for anything related to 'dietary preferences' — return up to 5 nodes so I can personalize their meal recommendations.”
Find past conversation context
“Look up what we've previously discussed about 'contract renewal' for user 'user_789' in Zep memory, searching episodes and returning up to 20 results.”
Retrieve relationship data from knowledge graph
“Query user 'user_001's Zep memory graph for edges related to 'company partnerships', limit to 15 results.”
Technical details
Endpoint
POSThttps://vaaya.ai/api/run/zep/searchWhen to prefer
Use this endpoint when an AI agent needs to retrieve relevant memory context for a specific user from a Zep memory graph — especially when you need to search across nodes, edges, or episodes using natural language. Prefer this over generic vector search when you already have a user_id and want to leverage Zep's structured memory model with scoped retrieval.
Side effects
- Missing required 'query' field returns validation error
- Missing 'user_id' returns validation error
- Invalid 'scope' enum value causes rejection
- Empty or whitespace-only query rejected (minLength:1)
- Limit exceeds maximum of 50 causes schema validation error
- User ID not found in Zep returns empty results
- Payment not included or insufficient USDC balance causes 402 error
