Feeds: Balances and Transfers APIs are live

Feeds is a new product type at Goldsky: enriched onchain datasets, ready to use. Each feed ships pre-indexed and enriched, with token metadata and USD prices already attached. Query a feed as a single API call, or stream it straight into your own database. You don't build an indexer, fan out RPC calls, or maintain a price feed.

Balances and Transfers are the first two feeds, live today. Send one address and get back what a wallet holds, or what it sent and received, across Ethereum, Base, Arbitrum One, Optimism, Polygon, BNB Smart Chain, and Robinhood Chain:

• Balances: a wallet's native and ERC-20 holdings with USD values and a total for the wallet. One response is enough to render a portfolio screen.
• Transfers: a wallet's native and ERC-20 transfers in and out, newest first, with the USD value at transfer time. Use it for deposit detection, "You received 50 USDC" notifications, and tax exports.

Simple pricing

$0.35 per 1,000 requests, with no monthly minimum. There's no per-chain surcharge, so a request across all seven chains costs the same as a request for one.

Ready for AI agents

Feeds ships with an OpenAPI spec and a copy-paste prompt for Claude Code, Cursor, and other coding agents, so an agent can wire wallet data into your app from one prompt.

What's next

More feeds are on the way beyond Balances and Transfers, including stablecoin and payment feeds, prediction markets, and tokenized assets, plus support for more chains, including non-EVM networks like Solana. Streaming feeds straight into your own database is coming soon.
