API Endpoints

Our GraphQL API endpoints are structured to support both testnet and mainnet access.

Below is the standard format:

https://<testnet|mainnet>.<network>.api.hgraph.<dev|io>/<pathname>

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

Accessing the Hedera GraphQL API

For accessing Hedera GraphQL endpoints, use the following pathname format:

/v1/<api-key>/graphql

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

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.
