# Lava Search

> Lava's first-party fan-out search aggregator: one HTTP call across 9 brokered providers (Tavily, Exa, Jina, Parallel, Perplexity Sonar, Firecrawl, Lava News, Serper, Brave) returning a unified normalized result set in `/sources`, or an LLM-synthesized answer with citations in `/answer` (sources are not echoed back — call `/sources` separately if you need them).

Lava's first-party fan-out search aggregator: one HTTP call across 9 brokered providers (Tavily, Exa, Jina, Parallel, Perplexity Sonar, Firecrawl, Lava News, Serper, Brave) returning a unified normalized result set in `/sources`, or an LLM-synthesized answer with citations in `/answer` (sources are not echoed back — call `/sources` separately if you need them). Best for agents that need broad cross-source coverage in a single round-trip with explicit partial-failure surfacing. Charges upstream costs plus a $0.005 markup on `/sources`, or a $0.03 markup plus LLM token cost on `/answer`.

2 endpoints available through Lava's AI Gateway. See the [Lava Search API docs](https://www.lava.so/docs) for full documentation.

<Info>Supports both **managed** (Lava's API keys) and **unmanaged** (bring your own credentials) mode.</Info>
