```

Example prompt: Do a standard-depth research on the competitive landscape of AI coding assistants in 2024 — who the main players are, their pricing, and how they differentiate.

## When to prefer this

Choose this endpoint when you need multi-source web research synthesized into a coherent answer, especially when the question requires gathering and combining information from multiple web pages. It is particularly valuable for deep or exhaustive research tasks where breadth of coverage matters. Prefer over single-URL scrapers or simple search APIs when you need synthesized insight rather than raw results.

## Known failure modes

- Input question exceeds 40,000 character limit — request rejected
- Invalid research_effort enum value — validation error returned
- Network or upstream search service failure — server error response
- Payment not completed via x402 protocol — 402 Payment Required returned
- Timeout for exhaustive research tasks on complex topics
