## When to prefer this

Choose this endpoint when you need Bing Copilot's AI-synthesized, conversational answers rather than raw web search links — ideal for agents that want a single structured AI-generated response to a query without managing API keys, accounts, or subscriptions. Prefer this over raw SERP endpoints when the goal is to get a summarized, AI-interpreted answer to a question rather than a list of ranked web links.

## Known failure modes

- Missing or empty 'q' parameter returns an error or empty result
- Payment failure or insufficient USDC balance blocks the request
- Bing Copilot service unavailability causes upstream errors
- Query triggers content moderation or safe-search filtering resulting in a filtered or empty response
- Rate limiting or throttling on upstream Bing service may cause timeouts
