Agent Tools API (Engine #2 — tool suite)

Deterministic web utilities every AI agent/app needs, as one reliable HTTP call each. No LLM, no paid services. cheerio/DNS only → fast cold starts, $0 marginal cost.

Endpoints

• GET /api/validate-email?email= — syntax + live MX/A DNS + disposable/role/free detection. Returns { valid_syntax, has_mx, accepts_mail, disposable, role_account, free_provider, deliverable, score }. (MX-level — no SMTP probe, which is slow/abusive.)
• GET /api/extract?url=&selectors={...} — CSS-selector scraping → structured JSON. Selector syntax: "css" (text), "css@attr" (attribute), "css[]" (all matches). href/src → absolute.
• GET /api/feed?url=&limit=25 — RSS/Atom feed → clean JSON items.

All hardened: http/https only · SSRF guard (DNS-resolved) · 7s timeout · size cap · CORS open.
