title: "WebSearchEngineEnum"
---

Which search engine to use. "auto" (default) uses native if the provider supports it, otherwise Exa. "native" forces the provider's built-in search. "exa" forces the Exa search API. "firecrawl" uses Firecrawl (requires BYOK). "parallel" uses the Parallel search API. "perplexity" uses the Perplexity Search API (raw ranked results).

## Example Usage

```python
from openrouter.components import WebSearchEngineEnum

# Open enum: unrecognized values are captured as UnrecognizedStr
value: WebSearchEngineEnum = "native"
```


## Values

This is an open enum. Unrecognized values will not fail type checks.

- `"native"`
- `"exa"`
