Endpoint
GEThttps://x402helper.xyz/89e509/answer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs a synthesized, direct answer from live web sources rather than a static knowledge base. It is well-suited for time-sensitive queries (past day/week/month/year), region-specific lookups, and any case where up-to-date information matters. Prefer it over static RAG pipelines when freshness is critical and over full browser automation when a summarized answer suffices.
Side effects
- Missing or empty 'query' parameter returns an error or empty result
- Payment not provided or rejected results in 402 Payment Required response
- Invalid 'timelimit' enum value causes request rejection
- max_sources exceeding 5 causes validation failure
- Queries returning no relevant web results yield an empty or low-quality answer
- Network timeout on source fetching may return partial results
