How this service works

Competitive landscape briefing for a pitch

When to prefer

Choose this endpoint when you need a narrative intelligence brief with cited sources on a market or category — not just raw search results or data points. It is preferable over the Ysaere quick brief when you need citations and sourcing for credibility or downstream verification. Use it over generic web search when you want a synthesized, analyst-style summary rather than a list of links. Best for due diligence, competitive research, pitch prep, or sector onboarding where referenced conclusions matter.

Side effects

Empty or very niche target market with insufficient source coverage may return a sparse brief or empty sources list
Overly long context or focus strings exceeding character limits will be rejected with a 400-level error
Payment failure or insufficient USDC balance will result in a 402 Payment Required response
Ambiguous or malformed target field may produce a generic or off-topic brief
Timeouts possible if source aggregation takes longer than expected under load
