The Covalent API provides comprehensive blockchain data from multiple chains, enabling the retrieval of balances, transactions, and contract details with a simple API call. On Pipedream, you can harness this API to create powerful automations and workflows that respond to blockchain events, aggregate data for analysis, and integrate with other apps for a wide array of use cases, such as notifying users of transaction events or updating databases with the latest blockchain states.
import { axios } from "@pipedream/platform"
export default defineComponent({
props: {
covalent: {
type: "app",
app: "covalent",
}
},
async run({steps, $}) {
return await axios($, {
url: `https://api.covalenthq.com/v1/1/block_v2/5000000/`,
auth: {
username: `${this.covalent.$auth.api_key}`,
password: ``,
},
})
},
})
The MongoDB API provides powerful capabilities to interact with a MongoDB database, allowing you to perform CRUD (Create, Read, Update, Delete) operations, manage databases, and execute sophisticated queries. With Pipedream, you can harness these abilities to automate tasks, sync data across various apps, and react to events in real-time. It’s a combo that’s particularly potent for managing data workflows, syncing application states, or triggering actions based on changes to your data.
import mongodb from 'mongodb'
export default defineComponent({
