GoldRush vs Zerion API

GoldRush or Zerion API: which one fits

Zerion API is a unified wallet and portfolio data API: balances, DeFi positions, NFTs, transactions, and PnL across 40+ EVM chains and Solana. GoldRush is a decoded multichain data API across 100+ chains including Bitcoin, with JSON-RPC and DEX pool spot prices. Both are REST data APIs with native x402.

Why choose GoldRush over Zerion API

The differences that matter when you ship multichain data, drawn from each product's public docs and pricing.

• Broader coverage, incl. Bitcoin

  Decoded data across 100+ chains including Bitcoin, which Zerion does not support. Zerion covers 40+ EVM chains and Solana.

• DEX pool prices

  Spot prices for DEX pools on major EVM chains such as Ethereum and Base, plus OHLCV candles for Hyperliquid markets. Zerion's charts are price-only timeseries, and it does not offer DEX analytics.

• JSON-RPC included

  GoldRush serves JSON-RPC on 30+ EVM chains. Zerion is a REST data API only, with no node service.

• x402 on both

  Both ship x402 pay-per-request. GoldRush pairs it with wider chain coverage and onchain analytics.

Same task on both APIs

Get a wallet's token balances and positions. Compare the request shape and how much each call returns.

// Zerion: wallet positions (API key as HTTP Basic username)
const auth = Buffer.from(process.env.ZERION_API_KEY + ":").toString("base64");
const res = await fetch(
  "https://api.zerion.io/v1/wallets/" +
  "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045/positions/?currency=usd",
  { headers: { Authorization: "Basic " + auth } }
);
const { data } = await res.json();

// GoldRush, wallet balances on any chain
const res = await fetch(
  "https://api.covalenthq.com/v1/eth-mainnet/" +
  "address/vitalik.eth/balances_v2/",
  { headers: { Authorization: "Bearer " + process.env.GOLDRUSH_API_KEY } }
);
const { data } = await res.json();
console.log(data.items);
