# Interface: SearxngRequestContext

Defined in: [batteries/tools/searxng/index.ts:69](https://github.com/NHTIO/ADK/blob/v1.20260609.0/src/batteries/tools/searxng/index.ts#L69)

Mutable context handed to each input-pipeline stage **before** the HTTP request is sent.

## Remarks

Stages mutate this in place (onion `(ctx, next)` style) to adjust the outgoing request —
inject or rotate auth headers, force a language, rewrite the query — or call
[SearxngRequestContext.shortCircuit](#shortcircuit) to skip the fetch entirely (e.g. a cache hit).
