How this service works
Semantically search a memory collection (namespace) and return the most relevant stored entries. The retrieval half of RAG.
Output
Returns a ranked list of up to top_k stored memory entries from the specified namespace that are most semantically similar to the query, ordered by relevance. Each entry reflects what was previously upserted into that namespace.
Example use cases
RAG context retrieval for agent responses
“Before you answer the user's question about our cancellation policy, search the 'company-docs' memory namespace for the 3 most relevant stored entries about 'subscription cancellation' so you can ground your answer in what we've stored.”
Personalized recall for a user profile namespace
“Search the 'user-prefs-alice' memory namespace for anything relevant to 'dietary restrictions' — return the top 5 matches so I can personalize her meal recommendations.”
Knowledge base lookup for a coding assistant
“Query the 'codebase-docs' namespace for the 10 entries most semantically similar to 'how authentication middleware works' so the agent can use that context when answering developer questions.”
Technical details
Endpoint
POSThttps://api.agishub.com/paid/memory-searchWhen to prefer
Choose this endpoint when an AI agent needs to retrieve contextually relevant stored knowledge from a named namespace before generating a response (classic RAG retrieval). Prefer it over keyword-based search when semantic similarity matters more than exact term matching, and when the data was previously upserted into this same provider's memory system.
Side effects
- Namespace does not exist — returns empty results or an error
- Query string is empty — rejected due to minLength:1 constraint
- top_k out of range (below 1 or above 20) — validation error
- No semantically similar entries found — returns empty result set
- Payment failure — x402 payment required, call rejected if payment not provided
