How this service works
Pay-per-call Web3 agent services: wallet, token and agent security audits; token prices, depeg checks and portfolio valuation; cited fact-checking and source research.
Output
Returns an array of search results (title, URL, snippet), an array of verifiable sources with URLs and content hashes, evidence objects linking claims to source indices, an overall risk score, a confidence score, and a content hash for the response — all tied to the original query.
Example use cases

“Search the Crucible dataset for known vulnerabilities in Compound Finance's governance mechanism and give me cited sources and confidence scores — return up to 5 results.”

“I need cited, evidence-backed research on the Terra UST depeg event from 2022 — search the Crucible research dataset and give me sources I can verify, up to 8 results.”
Smart contract audit background research
“Before auditing this new lending protocol, search Crucible's research dataset for past reentrancy attack case studies in DeFi lending and return up to 10 results with evidence and risk scores.”

Endpoint
POSThttps://crucible.unitynodes.com/research/datasetWhen to prefer
Choose this endpoint when you need citeable, source-verified research results from a curated Web3-focused dataset — especially when confidence scores, content hashes, and evidence traceability are required. Prefer this over generic web search when verifiability and risk scoring of research outputs matter, or when operating in a blockchain/DeFi context that demands auditable sourcing.
