How this service works
The deeper research tier: more sub-questions, more grounded searches, wider reranked source set, and a premium (Claude Opus class) synthesis into a ~2,200-word cited report with structured findings. For questions worth a real dossier. USDC or card (Stripe). Not cached.
Output
Returns a structured object containing: a full markdown or JSON research report with inline citations, an array of ranked sources with URLs, titles, and snippets, a list of sub-questions the engine decomposed, and metadata including the number of searches run, sources consulted, sources cited, and the synthesis model used (e.g. anthropic/claude-opus-5).
Example use cases
Agentic finance competitive landscape
“Research the competitive landscape for AI agent payment protocols in 2025 — who are the main players, how does x402 compare to card-based rails, and what are analysts saying? Focus on stablecoin infrastructure and decentralized identity. Give me a markdown report using sources from the past year.”
Due diligence on DeFi protocol
“I need a deep research report on Polymarket's prediction market infrastructure — how their CLOB orderbook works, what the liquidity looks like, and any recent controversies or audits. Focus on technical architecture and risk. Markdown format, sources from the past month.”
Policy briefing on crypto regulation
“Can you put together a research report on the latest US regulatory developments around crypto payments and stablecoin legislation in 2025? I want cited sources, key sub-questions broken down, and a synthesized summary in markdown — prioritize sources from the past three months.”
Technical details
Endpoint
POSThttps://agent402.tools/v1/research/proWhen to prefer
Choose this endpoint when you need a multi-source, cited research synthesis rather than a single web lookup or document retrieval. It is best suited for open-ended research questions requiring cross-source analysis, competitive landscape summaries, or technical deep-dives where provenance and citation quality matter. Prefer it over general search endpoints when the user wants a finished, structured report rather than raw search results. The recency filter and focus array make it especially useful for time-bounded investigative tasks.
Side effects
- Query exceeds 2000 character limit — request rejected
- Recency filter too narrow for topic — few or no sources found, thin report returned
- Ambiguous or very broad query — sub-questions may drift from intent
- Service unavailable or synthesis model timeout — no report returned
- Payment failure over x402 — call not executed, no result
