PolyDB: one API key, every data shape your agent needs PolyDB is a hosted multi-model database made for AI agents. One API key gives your agent a private, isolated database that holds many kinds of data at once. You don't need to set up or connect a separate service for each kind. What your agent can store and query - Memory and knowledge: session-scoped memories with semantic recall (store_memory / recall_memory), plus tenant-wide knowledge learned once and reused (store_knowledge / search_knowledge) - Vectors for RAG: store_vector / search_vectors, with collections created on first insert - Documents and SQL: JSON documents, plus read-only SQL over your tables (query_sql, which accepts SELECT, WITH, EXPLAIN and SHOW) - Key-value with TTL - Graphs: nodes, edges and graph queries - Time-series and temporal: metrics over time, and time-travel queries on versioned entities - Geospatial: nearby and bounding-box search - Full-text search - Files: blobs and S3-compatible object storage - Streams: publish and consume Made for agents - 69 tools with typed input and output schemas. search_schema returns the catalog grouped by data type. - Multiple named databases per account. Pass database on any call to pick one. - Stable error codes. Auth errors include how_to_fix and ready-to-paste setup snippets, so an agent can tell a human exactly what to fix. - Tenant isolation. Every request is scoped to the account that owns the key, and you can't see other tenants' data.
