# Voice Agents docs URL migration - atoms → voice-agents, atoms-platform → platform

> The Voice Agents product now lives under /voice-agents/ on the docs site, replacing the older /atoms/ prefix.

The Voice Agents product now lives under `/voice-agents/` on the docs site, replacing the older `/atoms/` prefix. The main tab's URL also drops the brand doubling: `/atoms/atoms-platform/*` becomes `/voice-agents/platform/*`. All other tabs move too. `/atoms/developer-guide/*` becomes `/voice-agents/developer-guide/*`. Same for `api-reference`, `mcp`, `integrations`, `developer-tools`, and `changelog`.

Every old URL 301-redirects to its new equivalent. Bookmarks, external links, and search-indexed pages keep resolving. The migration matches the industry convention (Retell, ElevenLabs, Vapi, AssemblyAI all use generic function-based top-level slugs); no peer uses the brand-doubled shape our old URLs had.

API endpoints and SDK identifiers are unchanged. `POST /atoms/v1/agent`, `AtomsClient`, `from smallestai.atoms import AtomsClient`, `@smallest/atoms` - all still the same. Only docs URLs moved.
