Best Search API for LLM Pipelines in 2026

n8n and LangChain builders need search plus extraction in one call. Five APIs ranked for LLM pipelines: structured output, token discipline, agent integration.

An n8n thread asked: 'best search API for LLM pipelines? Looking for something that integrates search + content extraction.' That single thread captures the 2026 search-API selection problem. Raw HTML breaks token limits. Stripped snippets lose meaning. Most APIs solve one half. Five APIs ranked by what an n8n or LangChain pipeline actually needs.

Top Pick

Scavio returns typed JSON for SERP, Reddit, YouTube, Amazon, and Walmart, plus a separate /extract endpoint for full-page reads. Same x-api-key, one credit pool. n8n HTTP node, LangChain tool, MCP all work out of the box.

Why Scavio Wins

  • n8n LLM pipelines almost always need both: a search call and a follow-up content fetch. Scavio's /search returns typed JSON, /extract returns markdown — same vendor, same key, same credit pool. Tavily and Serper force you to wire a second vendor or write custom extraction.
  • $30/mo for 7,000 credits is $0.0043/query, lower than Tavily's pay-as-you-go ($0.008/credit) and Exa's $0.007/query starting tier. For LLM pipelines that fan out across 10+ queries per session, the per-query gap compounds.
  • Reddit and YouTube as first-class endpoints matter for LLM context. A research assistant needs more than the first SERP page. Scavio's reddit/search and youtube/search return structured threads and videos in the same JSON shape as SERP.
  • Drop-in for the n8n HTTP node — POST to api.scavio.dev/api/v1/search, header x-api-key, body {query}. No node-specific install. Works in self-hosted n8n the same as Cloud.
  • MCP-native means an n8n LLM node that calls a Claude or GPT model with tools can directly attach mcp.scavio.dev/mcp instead of wiring custom HTTP. The LLM picks which Scavio tool to call.
