# WebFetchEngineEnum - Go SDK

> WebFetchEngineEnum type definition

<Warning>
  The Go SDK and docs are currently in beta.
  Report issues on [GitHub](https://github.com/OpenRouterTeam/go-sdk/issues).
</Warning>

Which fetch engine to use. "auto" (default) uses native if the provider supports it, otherwise Exa. "native" forces the provider's built-in fetch. "exa" uses Exa Contents API. "openrouter" uses direct HTTP fetch. "firecrawl" uses Firecrawl scrape (requires BYOK). "parallel" uses the Parallel extract API.

## Example Usage

```go lines theme={null}
import (
	"github.com/OpenRouterTeam/go-sdk/models/components"
)

value := components.WebFetchEngineEnumAuto

// Open enum: custom values can be created with a direct type cast
custom := components.WebFetchEngineEnum("custom_value")
```
