Endpoint
GEThttps://api.x-402.online/v1/brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, structured, cited research brief on any topic without setting up an account — especially useful for AI agents that need synthesized intelligence with source attribution in a single pay-per-call request. Prefer it over general web search APIs when you want the output pre-structured into summary, key points, and open questions rather than raw search results.
Side effects
- Empty or overly vague query returns a thin or generic brief
- Very niche queries may return few or no sources
- Payment failure (402) if USDC/Base wallet is not funded or x402 protocol handshake fails
- Rate limiting or service unavailability returns 5xx errors
- Query string missing returns validation error
