Envio is a multi-chain indexer. There's a single GraphQL API endpoint that aggregates data across chains. This approach differs from other vendors like The Graph, which require a separate indexer for each chain where Sablier is available.

In the table below, you will see three URLs:
Production URL: requires a Studio API key for making queries.Testing URL: doesn't require an API key but it's rate-limited to 3000 queries per day. Opening this URL in the browser opens a GraphiQL playground.Explorer URL: The explorer URL for the indexer, if available.
To learn how to create a Studio API key, check out this guide.
The API key has to be provided via an Authorization: Bearer <API_KEY> header. Here are two examples in curl and JavaScript:
- curl
- JavaScript
curl -X POST \
-H "Authorization: Bearer <API_KEY>" \
-H "Content-Type: application/json" \
-d '{"query": "{ _meta: { block { number } } }"' \
<PRODUCTION_URL>
import { GraphQLClient } from "graphql-request";
async function getBlockNumber() {
const client = new GraphQLClient("<PRODUCTION_URL>", {
headers: {
Authorization: `Bearer <API_KEY>`,
},
});
const query = `query { _meta: { block { number } } }`;
const result = await client.request(query);
console.log(result);
}
