When to prefer

Choose this endpoint when you need programmatic, pay-per-call access to trending topic signals with fine-grained control over regions, sources, and time windows. Prefer this over social media APIs or search trend tools when you need structured JSON trend data integrated with a micro-payment model on Base/USDC and don't want subscription overhead.
