工具清单
工具（3）
🟢web_extract_preview(url, fields)
Free keyless live web read: fetch ONE public URL now and get the title, metadata and boilerplate-stripped main-content text (JS/SPA pages recovered without a browser), plus a prompt-injection screen flag. SSRF-guarded. Markdown, the full link graph and 10-URL batches are in the paid /web/extract ($0.003) — call get_premium_access.

}
},
"required": [
"url"
]
}🟢sitemap_preview(site, contains)
Free keyless site enumeration: discover a domain's sitemaps (robots.txt, fallback /sitemap.xml) and return up to 20 page URLs with lastmod. The paid /web/sitemap ($0.003) returns up to 5000 URLs across 10 sitemap files with a substring filter — call get_premium_access.
输入模式
{
"type": "object",
"properties": {
"site": {
"type": "string",

]
}🟢get_premium_access
Return the paid x402 rail: the metered depth layers (hosted 10-ATS search, normalized compensation, per-company hiring-intent signal, company enrichment, email deliverability) with exact prices (USDC on Base), the pay-to address, and how the 402 flow works. No account; an x402-aware client pays inline from the agent's wallet.
