## 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 pulsescanner-dex-protocols-registry-b88d3f53
```

Example prompt: Can you pull up all the DEX protocols that are registered on PulseChain and show me which factory contracts they were discovered by?

## When to prefer this

Use this endpoint when you need a comprehensive registry of DEX protocols and their factory contracts specifically on PulseChain (chain ID 369). Prefer this over general blockchain explorers when you need structured, machine-readable DEX protocol data for PulseChain DeFi integrations, analytics, or aggregator development.

## Known failure modes

- Payment not included or insufficient — HTTP 402 response requiring USDC payment
- Network or upstream service unavailability — HTTP 5xx error
- Empty result if no protocols are registered (unlikely but possible)
- Malformed response if PulseChain indexer is out of sync
