## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability beggar-bot-protocol-hallmarks-lookup-13735ee0
```

Example prompt: Can you pull the protocol hallmarks for Uniswap on Base mainnet — I want to see the notable events and milestones listed for it on DefiLlama?

## When to prefer this

Use this endpoint when you need structured historical hallmark/milestone data for a specific DeFi protocol on Base mainnet and have a valid DefiLlama protocol slug. Prefer this over manual DefiLlama API calls if you're already using the Beggar Bot x402 payment flow. Best suited for agents doing DeFi research, protocol due diligence, or timeline construction on Base.

## Known failure modes

- Invalid or unrecognized DefiLlama protocol slug returns an error or empty result
- Protocol not deployed on Base mainnet returns no data
- Payment not received (x402) results in 402 Payment Required response
- Network parameter typo (e.g. wrong chain name) may return no results
- Rate limiting or Cloudflare Worker errors may cause 5xx responses
