Serper
/serper
Serper is the fastest, most affordable way to put live Google results into an application. A single call returns clean, structured JSON for any Google vertical — web, images, news, places, maps and scholar — so results drop straight into an LLM prompt or a ranking pipeline with no parsing overhead. Its blend of speed and flat, low pricing has made it a default search backend for agent frameworks like LangChain and CrewAI, and a webpage-scraping endpoint rounds out the toolkit when you need the page behind a result.
Call Serper through the gateway
Same paths, parameters and responses as Serper's native API — auxiliar injects the upstream key server-side and debits the provider's metered cost from your credits.
curl https://api.auxiliar.ai/serper/<native-path> \ -H "Authorization: Bearer $AUXILIAR_API_KEY"
Exact endpoints and parameters: docs.auxiliar.ai/serper. An empty balance returns HTTP 402 — no silent degradation; see how billing behaves.
