Technical details
Endpoint
POSThttps://nova-demand-worker.vercel.app/x402/trend?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, aggregated trend intelligence filtered by topic focus, geographic region, and source — particularly in agent workflows that require verifiable, hashable trend snapshots. Prefer it over generic web search when you want clean, machine-readable trend arrays with provenance and content hashing, and when paying per-call via x402/USDC on Base is acceptable.
Side effects
- Empty trends/emerging arrays if no matching content found for given focus or region filters
- Payment failure if x402/USDC transaction on Base is not completed correctly
- Invalid input if focus array exceeds 10 items or limit exceeds 50
- Source filter may return no results if specified sources are unavailable or unsupported
- Rate limiting or quota exhaustion returning non-200 status
