What is an AtroUI Host API?
A Host API is copied UI plus a thin Next.js route.ts plus a hardened handler in the atroui package. You bring API keys. AtroUI is not a hosted AI or mail SaaS.
Definition
Host API = the consumer’s App Router route that calls atroui/api/<name>. The host is their Next.js app. The API is validation, honeypot, body caps, and rate limits — then SMTP, Resend, Hugging Face, Gemini, or xAI using env on that host.
Why it matters
UI kits stop at the form. Random GitHub routes skip honeypot and 429. Host APIs are the middle: own the files, borrow the boring security, keep the keys.
