Trieve Search API
Open-source infrastructure for building search and RAG pipelines combining dense vector search, sparse vector search (SPLADE), BM25 full-text, and cross-encoder reranking. Trieve provides a REST API for chunk management (ingest, update, delete) and search (semantic, fulltext, hybrid), plus recommendations and RAG with citations. Self-hostable with Trieve Cloud managed option. Strong focus on search quality via multi-stage retrieval.

⚙ Agent Friendliness
🔒 Security
Apache 2.0 open-source — auditable. HTTPS enforced. Dataset-scoped API keys. Self-hosted option for data control. Early-stage company — SOC2 status not confirmed; verify for enterprise use.
⚡ Reliability
Best When
You want best-in-class search quality for RAG via multi-stage hybrid retrieval (dense + sparse + reranking) with an open-source option and simple REST API.
Avoid When
You need enterprise managed service with guaranteed SLAs and compliance certifications — Trieve is early-stage for enterprise use cases.
Use Cases
- • Build RAG pipelines for AI agents with Trieve's hybrid search combining dense embeddings + BM25 for better retrieval than pure vector search
- • Implement multi-stage retrieval (search → rerank) for agent knowledge bases to maximize answer relevance
- • Create recommendation systems for agents using Trieve's recommendation API based on similar chunks
- • Build search-augmented agent workflows where agents search Trieve before generating answers, with citation tracking
- • Index and search large document collections for agents using Trieve's chunking API with automatic embedding
Not For
- • Simple semantic search without hybrid retrieval needs — Pinecone or Weaviate are simpler for basic vector search
- • Enterprise deployments needing SOC2 and managed SLA — Trieve Cloud is early-stage; verify compliance status
- • Non-English content — hybrid search quality varies by language; verify SPLADE and BM25 language support for your use case
Interface
Authentication
API keys with read/write/admin scopes per dataset. Keys generated in Trieve dashboard or via API. Dataset-scoped keys for multi-tenant access control. API key in TR-API-Key header.
Pricing
Generous free tier for prototyping. Self-hosting is free (Apache 2.0). Trieve Cloud pricing is competitive. LLM costs for RAG with generation are passed through at cost.
Agent Metadata
Known Gotchas
- ⚠ Hybrid search (dense + sparse + BM25) is more expensive per request than pure vector search — configure search type based on budget and quality needs
- ⚠ Chunk size affects retrieval quality — too large (>1000 tokens) reduces precision; too small (<50 tokens) loses context
- ⚠ SPLADE sparse vectors require separate embedding model — verify SPLADE support is enabled in your Trieve deployment
- ⚠ Cross-encoder reranking adds latency (~200ms) — use only when retrieval quality justifies the cost
- ⚠ Dataset must be created before inserting chunks — agents must manage dataset lifecycle
- ⚠ Embedding model is configured per dataset and cannot be changed after creation — choose embedding model carefully at setup
- ⚠ Self-hosted deployment requires running Qdrant, Qdrant BM25, Redis, and Trieve services — significant operational overhead
