Alchemy

🚀 Quickstart

Connect to Alchemy with Nango and see data flow in 2 minutes.

Create the integration

In Nango (free signup), go to Integrations -> Configure New Integration -> Alchemy.

Authorize Alchemy

Go to Connections -> Add Test Connection -> Authorize, then enter your Alchemy API key. Later, you’ll let your users do the same directly from your app.

Call the Alchemy API

Let’s make your first request to the Alchemy API to get the current ETH price. Replace the placeholders below with your Environment API key, integration ID, and connection ID:

cURL
Node

curl "https://api.nango.dev/proxy/prices/v1/tokens/by-symbol?symbols=ETH" \
  -H "Authorization: Bearer <NANGO-API-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>"

Install Nango’s backend SDK with npm i @nangohq/node. Then run:

import { Nango } from '@nangohq/node';

const nango = new Nango({ apiKey: '<NANGO-API-KEY>' });

const res = await nango.get({
    endpoint: '/prices/v1/tokens/by-symbol',
    params: { symbols: 'ETH' },
    providerConfigKey: '<INTEGRATION-ID>',
    connectionId: '<CONNECTION-ID>'
});

console.log(res.data);

Or fetch credentials with the Node SDK or API.✅ You’re connected! Check the Logs tab in Nango to inspect requests.

API gotchas

Chain APIs (JSON-RPC and NFT API) are served from per-network hosts such as https://eth-mainnet.g.alchemy.com, not from https://api.g.alchemy.com. Call them with baseUrlOverride set to the network host; Nango keeps the connection’s credentials and headers. See Chain API supported chains.
