Periodic Table API

Periodic Table retrieves chemical element data by element name or symbol. Responses include atomic number, category, phase, block, standard group and period positions, and CPK hex colors, with paid plans adding atomic mass and thermal metrics.

The Periodic Table API provides a simple, reliable way to integrate periodic table functionality into your applications. Built for developers who need production-ready periodic table capabilities without the complexity of building from scratch.

Every APIVerve endpoint returns the same envelope — check status, then read data:

{
  "status": "ok",
  "error": null,
  "data": { ... }
}
