Compare Felo OpenAPI, SerpAPI, and Tavily for AI agent search — pricing, capabilities, integration, and which gives agents the most power.

SerpAPI and Tavily are established search API providers. But AI agents need more than search results — they need extraction, memory, and output. Here's how Felo OpenAPI's search stack compares.

What Each Platform Offers​

SerpAPI​

SerpAPI provides search engine results through an API:

  • Google, Bing, and other search engine results
  • Structured SERP data
  • Page snippets and metadata
  • Some full-page extraction (additional cost)

Strengths: Reliable SERP data, wide search engine coverage, established API.

Limitations: Raw SERP data requires additional parsing. No social media, video, memory, or output tools.

Tavily​

Tavily is built specifically for AI agents:

  • Search optimized for LLM consumption
  • Structured results with answers
  • Web page extraction
  • Agent-friendly response format

Strengths: Clean, agent-friendly search results. Good for RAG workflows.

Limitations: Search-focused only. No social media data, video transcripts, memory, or output generation.

Felo OpenAPI​

Felo OpenAPI provides a multi-layer search and tool stack:

  • AI Search (POST /v2/chat) — conversational search with structured results
  • Web Fetch (POST /v2/web/extract) — full page extraction
  • X Search (POST /v2/x/tweet/search) — social media data
  • YouTube Subtitles (GET /v2/youtube/subtitling) — video transcripts
  • LiveDocs — persistent memory with semantic retrieval
  • Output APIs — PPT, mindmap, landing page, image generation

Strengths: Complete search + tool + memory + output stack. One key, one platform.

Limitations: Newer platform, still building model routing features.

The Real Cost Comparison​

When you factor in all the tools an agent needs:

SerpAPI stack:

  • SerpAPI subscription (search)
  • Separate extraction tool
  • Separate social media API
  • Separate memory/database
  • Separate output tools
  • Total: 4-6 subscriptions

Tavily stack:

  • Tavily subscription (search + extraction)
  • Separate social media API
  • Separate memory/database
  • Separate output tools
  • Separate model API
  • Total: 4-5 subscriptions

Felo OpenAPI:

  • One subscription covers search, extraction, social data, video, memory, output, AND models
  • Total: 1 subscription

When to Use SerpAPI or Tavily​

Use SerpAPI when you need deep SERP data across multiple search engines and are building everything else yourself.

Use Tavily when you want clean, agent-friendly search results and are building other tool integrations separately.

When to Use Felo OpenAPI​

Use Felo OpenAPI when your agent needs the full stack — search, extraction, social data, video, memory, and output — without managing multiple subscriptions, API keys, and protocols.
