Helium API

⭐ Beginner's Pick Blockchain / No Auth Required Beginner HTTPS
Free to Use Varies (check documentation)

Overview

The Helium API provides access to legacy blockchain data for the Helium IoT network — hotspot locations, earnings, network coverage, and device activity. Useful for building dashboards or analytics tools on top of the Helium network.

💡

Beginner Tip

Note that this API covers the legacy Helium L1 blockchain data (pre-2023 Solana migration); for current data, also check the Helium Solana-based APIs and the Nova Labs data endpoints.

Available Data

Helium data via REST API
JSON-formatted response data
Freely accessible without authentication

Example Response

JSON Response
{
  "status": "success",
  "data": {
    "result": "Data from Helium",
    "description": "Helium is a global, distributed network of Hotspots that create public, long-range wireless coverage",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

address Unique base58-encoded identifier for this Helium hotspot on the blockchain.
name Human-readable animal-based name assigned to the hotspot (e.g. 'tall-purple-whale').
status.online 'online' or 'offline' — indicates whether the hotspot is currently connected to the network.
location H3 hexagonal grid cell index representing the hotspot's geographic location.
reward_scale Multiplier (0.0–1.0) applied to hotspot earnings based on network density in its area.
cursor Pagination token; pass as query parameter to retrieve the next page of results.

Implementation Example

const url = "https://docs.helium.com/api/blockchain/introduction/";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

What Can You Build?

Common Errors & Troubleshooting

404 Not Found Using an incorrect hotspot address or a resource that doesn't exist in the legacy blockchain
Verify the hotspot b58 address is correct; use the /v1/hotspots endpoint to search by name first.
Cursor-based pagination not working Forgetting to pass the 'cursor' parameter when paginating through large result sets
Check the response for a 'cursor' field; pass it as a query parameter in the next request to get the following page of results.
Empty or outdated data The legacy blockchain data is no longer updated after the Solana migration
For post-migration data, use the Helium Solana RPC or the Nova Labs Helium API; this endpoint is read-only historical data.
