Deep Research

Autonomous multi-domain research agent with 26 specialized endpoints spanning academic papers, preprints, biomedical literature, chemistry, demographics, and live web search. Each call is a real x402 micropayment ($0.001–$0.03 USDC).

How to call endpoints

Use the helper script for all gateway calls:

bash {baseDir}/scripts/research.sh METHOD ENDPOINT 'JSON_BODY'

GET endpoints pass JSON as query params. POST endpoints send JSON body.

Research workflow

When the user asks you to research a topic, follow this strategy:

1. Start broad — use web_search or web_qna to get an overview of the topic.
2. Go deep — based on initial results, call domain-specific tools (papers, preprints, biomedical, chemistry, demographics) for authoritative sources.
3. Extract details — use web_extract to pull full content from promising URLs found in step 1.
4. Cross-reference — search the same topic across multiple databases (OpenAlex + Crossref + arXiv) for comprehensive coverage.
5. Trace citations — use papers_citations or scholarly_citations_count to find influential related work.
6. Synthesize — combine all findings into a structured, sourced answer.

Be cost-aware. Each call costs real micropayments. Don't make redundant calls, but don't skimp when thoroughness matters.

Always cite sources with DOIs, URLs, PMIDs, or arXiv IDs when available.

Research modes

Adapt your strategy based on what the user needs:

Quick — 1-3 calls. Use web_qna for a fast answer, or one domain-specific search if the topic is clearly academic/biomedical/chemical.

Deep — 5-15 calls. Search multiple databases, cross-reference findings, trace citation graphs, extract full articles. Produce a comprehensive report with sections and citations.

Fact-check — 3-7 calls. Start with web_search to find the claim in context, then cross-reference with academic sources. Deliver a clear verdict with evidence.

Compare — 4-10 calls. Research each topic independently across the same databases, then structure findings side-by-side.

Data sources
