SerpApi, the world's leading platform for structured search data APIs, today announced the launch of Markdown output. Available across all SerpApi APIs, it enables developers to deliver real-time search results to large language models and AI agents in a more token-efficient format.
Now included in SerpApi's 100+ APIs at no additional cost, Markdown output transforms the same structured search data available in JSON into clean, LLM-friendly Markdown. The new format reduces token consumption by roughly 50% on average, with some APIs seeing reductions of up to 90%, helping developers fit more relevant context into model context windows.
"As developers increasingly build AI agents and LLM-powered applications, the way search data is consumed is changing," said Julien Khaleghy, CEO and founder of SerpApi. "When data is consumed by AI, it doesn't need many elements necessary for JSON. Markdown has emerged as the dominant language of AI models. We incorporated Markdown output so developers can provide real-time search results to their AI systems in a format that's easier for models to consume while significantly reducing token usage."
The launch of Markdown output represents latest step in SerpApi's efforts to build infrastructure purpose-built for AI and agentic applications. Developers can choose between JSON and Markdown results on request-by-request basis, depending on needs. While JSON remains ideal for software development and structured data processing, Markdown output is optimized for LLM and agent-based workflows where token efficiency is critical.
As AI systems increasingly rely on real-time search data to reason, verify, and act autonomously, access to fresh and trustworthy information is becoming foundational infrastructure. SerpApi believes web grounding is a core building block of the AI economy, enabling accuracy and reliability of AI-powered applications. SerpApi's library of more than 100 APIs helps AI systems access current information in real time rather than relying solely on static training data.
"The real benefit is making better use of an AI model's context window," added Khaleghy. "Because context is limited, the input should be concise and focused on the most important information. Our Markdown output removes unnecessary data, helping AI models process more useful information with fewer tokens."
Unlike separate endpoints or new APIs, Markdown output works immediately with existing SerpApi integrations. Developers can access Markdown responses through a query parameter, endpoint, or request header, with no additional configuration required. Markdown output is available across all existing SerpApi APIs and search engines, using same integrations, credits, and search infrastructure developers already rely on. Available today across all plans, APIs, and supported search engines.
