Capabilities include:</p>\n<ul>\n<li><strong>Company collections</strong> — top companies, all companies, currently hiring, non-profits, diversity data</li>\n<li><strong>Batch lookup</strong> — companies by YC batch (e.g., Winter 2025, Summer 2024)</li>\n<li><strong>Industry filter</strong> — companies by industry (fintech, healthcare, B2B, etc.)</li>\n<li><strong>Tag filter</strong> — companies by tag (AI, developer tools, SaaS, climate, etc.)</li>\n<li><strong>Metadata</strong> — overall YC stats, valid batch/industry/tag names</li>\n<li><strong>Client-side search</strong> — find companies by name or description via jq filters</li>\n</ul>\n<p><strong>This is a read-only data source.</strong> The API serves static JSON files — no write operations exist.</p>\n<h2>Authentication</h2>\n<p>None required. The API is public and free — just <code>curl</code> the endpoints.</p>\n<h2>Triggers</h2>\n<ul>\n<li>\"YC companies in fintech\", \"top Y Combinator companies\", \"latest YC batch\"</li>\n<li>\"YC startups hiring\", \"find YC companies tagged AI\", \"W25 batch\"</li>\n<li>\"Y Combinator portfolio\", \"startup research\", \"which YC companies do X\"</li>\n<li>Any mention of Y Combinator or YC in context of startup/venture research</li>\n</ul>\n<h2>Platform</h2>\n<p>Works on <strong>Claude Code</strong> and other CLI-based agents.
