Why Real-Time Search APIs Are Essential in 2025
The internet changes by the second. Search results, e-commerce listings, social media feeds, and news updates constantly evolve. For AI agents, marketing tools, and research platforms, access to fresh, structured data is essential. Real-time search APIs provide this by:

- Supporting fast decision-making for startups, AI tools, and marketers.
Affordability is especially important as developers often need thousands—or millions—of API calls monthly, and high-cost APIs can quickly become unsustainable.
