工具（36）
⚪preview_endpoint(endpoint, url)
FREE. See what a paid WebLens endpoint costs and what it returns before paying: the live price, a one-line summary, and a recorded sample of the exact response shape. Endpoints with no paid upstream (/fetch/basic, /contents, /map) also run a real truncated LIVE preview when you pass a url; SerpAPI- and Anthropic-backed endpoints return the recorded sample only, because free live runs there would burn upstream credits. Price: free

}🟢deep_research(query, depth)
Multi-step cited research in one call: plans sub-questions, searches each, fetches and dedupes sources, then synthesizes an answer with inline [n] citations, key findings, and gaps. Unlike `research` ($0.08, one search + summary) this decomposes the question and cites every claim.

}⚪domain_intel(domain)
Everything about a domain in one call: who registered it and when, when it expires, its DNS records, the mail and DNS providers behind them, the SaaS vendors its TXT verification tokens reveal (Google Workspace, Microsoft 365, Salesforce, Atlassian, Okta, …), SPF/DMARC posture, and risk flags like newly-registered or no-registrar-lock. Use for vendor due diligence, security triage, phishing checks and prospect research. Price: $0.005

"required": [
"domain"
]
}🟢project_due_diligence(domain, tokenAddress, chain)
Off-chain due diligence on a project's web presence — the half an on-chain rug checker cannot see. Returns domain age and registrar, whether a team page, whitepaper, docs and socials exist, whether the site is an off-the-shelf template, and a cross-check of a contract address against the addresses actually printed on the project's own website (a mismatch is a strong impersonation signal). Gives weighted risk signals and an A-F grade. Reads NOTHING on-chain — pair it with a contract/liquidity checker. Price: $0.05
