REST API Endpoints

Our Hedera mirror node REST API follows this structure:

/v1/<api-key>/<full-rest-endpoint>

For example:

https://mainnet.hedera.api.hgraph.dev/v1/<api-key>/api/v1/transactions

Alternatively, you may pass your API key in the Authorization header. If using this method, omit the <api-key> section from the URL pathname.

  • For testing and development purposes, use the .dev environment.
  • For live, production purposes, use .io environment.

Obtaining an API Key​

To access our API, you will need a valid API key. Visit your account dashboard to generate a key or contact support.

note

We are currently upgrading our systems (for self-serve API key generation) and documentation. This page will be updated soon.
