answers 402

query -> structured search results (title, url, snippet), up to 10 per call. Backed by three providers with automatic failover (DataForSEO primary, Tavily and Serper as fallback) so a single provider outage doesn't take the endpoint down. Pass region=tw for a Traditional Chinese / Taiwan-region search lane. Results are cached for 24 hours per query+region.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
