tools
answer_question
Get a grounded answer with inline [n] citations: searches the web, fetches sources, and answers strictly from them. Price: $0.05
Input schema
{'type': 'object', 'required': ['query'], 'properties': {'query': {'type': 'string', 'description': 'The question to answer'}, 'sources': {'type': 'number', 'description': 'Web sources to search, fetch, and cite (1-5, default: 3)'}}}
batch_fetch
Fetch multiple URLs in parallel. Efficient for bulk operations. Price: $0.0015/URL
Input schema
{'type': 'object', 'required': ['urls'], 'properties': {'urls': {'type': 'array', 'items': {'type': 'string'}, 'description': 'URLs to fetch (2-20)'}}}
compare_urls
Compare 2-3 webpages and get AI-generated analysis of differences. Price: $0.05
Input schema
{'type': 'object', 'required': ['urls'], 'properties': {'urls': {'type': 'array', 'items': {'type': 'string'}, 'description': 'URLs to compare (2-3)'}, 'focus': {'type': 'string', 'description': 'What to focus comparison on'}}}
crawl_site
Crawl a site and get clean markdown for every page in one synchronous call (no polling). Same-host BFS with depth and page-budget limits, robots.txt honoured by default. Price: $0.0015 per requested page (1-25) — you are billed for the requested budget, not the pages returned
Input schema
{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'Start URL — the crawl stays on this host'}, 'limit': {'type': 'number', 'description': 'Page budget (1-25, default: 10) — charged per requested page'}, 'exclude': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Skip URLs whose path+query contains one of these substrings'}, 'include': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Only crawl URLs whose path+query contains one of these substrings'}, 'timeout': {'type': 'number', 'maximum': 30000, 'minimum': 5000, 'description': 'Per-page timeout in ms (default 10000)'}, 'maxChars': {'type': 'number', 'maximum': 50000, 'minimum': 500, 'description': 'Per-page content character cap (default 8000)'}, 'maxDepth': {'type': 'number', 'description': 'Link depth from the start URL (0-3, default: 2)'}, 'respectRobots': {'type': 'boolean', 'description': 'Honour robots.txt (default: true; disable only for sites you control)'}}}
deep_research
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. SLOW: a standard run takes ~30-60 seconds — use a generous client timeout and do not retry on timeout. Price: $0.20 standard (3 sub-questions, 8 sources) / $0.35 deep (5 sub-questions, 12 sources)
Input schema
{'type': 'object', 'required': ['query'], 'properties': {'depth': {'enum': ['standard', 'deep'], 'type': 'string', 'description': 'Research tier: standard = 3 sub-questions / 8 sources ($0.20); deep = 5 / 12 ($0.35). Default: standard'}, 'query': {'type': 'string', 'description': 'The research question (1-500 chars)'}}}
detect_tech
What a website is built and run on, from a single fetch: framework, CMS, ecommerce platform, CDN, analytics, payments, support widgets and web server — each reported with the response header or HTML marker that proves it. Use for competitive research, sales prospecting and vendor due diligence. Price: $0.005
Input schema
{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'Site URL to fingerprint'}}}
domain_intel
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
Input schema
{'type': 'object', 'required': ['domain'], 'properties': {'domain': {'type': 'string', 'description': 'Domain to inspect, e.g. "stripe.com". A full URL is reduced to its hostname.'}}}

package_intel
Should you depend on this package? One call returns version, license, deprecation status WITH the maintainer's reason, weekly/monthly downloads, last release date, maintainer count, npm's quality/popularity/maintenance scores, and health signals (deprecated, no-recent-release, no-license, single-maintainer, no-public-repository). Supports npm and PyPI. Price: $0.003

preview_endpoint
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
Input schema

project_due_diligence
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
Input schema
{'type': 'object', 'required': ['domain'], 'properties': {'chain': {'type': 'string', 'maxLength': 32, 'minLength': 2, 'description': 'Optional chain label, e.g. base, ethereum, solana'}, 'domain': {'type': 'string', 'maxLength': 253, 'minLength': 3, 'description': 'Project website, e.g. "example.org"'}, 'tokenAddress': {'type': 'string', 'maxLength': 80, 'minLength': 20, 'description': 'Optional contract address to cross-check against the site'}}}
