Indexer API
Prerequisites
You must have an access to the Calimero console to interact with Indexer.
Configuration
To be able to call Indexer API you must set few parameters:
- Endpoint
- Authorization token
Endpoint
Endpoint is constructed from multiple parts:
- networkId: can be either testnet (with suffix: -calimero-testnet) or mainnet (with suffix:-calimero)
- shardId: unique identifier of your shard. Consist of user defined shard name and network suffix. All parts are required.
https://api.{{networkId}}.calimero.network/api/v1/shards/{{shardId}}/indexer-graphql/graphql
You can find it directly in the Console.
Authorization token
You must be authorised in order to fetch data. Use existing token or create a new one through the Console UI.
- Login in Calimero Console.
- Select the same shard as set in the previous step.
- Select Security tab from side menu and open Token page.
- On the Token page find "Create a new token" action and generate a new token.
Authorization token must be provided in header:
Authorization: {{token}}
