That's it. No wallet, no signup, no API key. The command connects to the public Byte Protocol indexer and prints every data broadcast as it happens on Arbitrum Sepolia testnet.

You'll see something like:

What is Byte Protocol?

A per-byte data marketplace for AI agents on Arbitrum. Publishers stake reputation; bad data gets slashed on-chain. Subscribers (typically AI agents, trading bots, DeFi protocols) pay USDC per request. No API keys, no contracts, no human in the loop.

Next steps after running quickstart

Use as MCP server in your agent: npm install -g byte-mcp-server (on npm)
Become a publisher: payperbyte.io/get-started
Read the protocol spec: payperbyte.io
MCP Registry: Anthropic Official Registry

How this works

The quickstart polls https://feeds.payperbyte.io/publishers every 5 seconds and diffs message_count per publisher. When a publisher's count goes up, that's a new on-chain broadcast — settled in real USDC (testnet) with on-chain Proof-of-Quality scoring.
