Blockchain API

Endpoints

The Helium blockchain API serves up the blockchain from a database that is filled by a blockchain node that populates the database as blocks come in.

While anyone can run a node and a corresponding API, the Helium hosted version offers up the API through two endpoints.

  • https://api.helium.wtf — Beta, scalable endpoint for new features and tests. Currently connected to mainnet. This endpoint is used for feature development. Submitted transactions may get dropped.

  • https://api.helium.io — Stable, scalable production service. Connected to mainnet.

Routes

The API routes are grouped together in sub-pages of this page. Refer to the subpages for details.
