```sh
zero fetch --capability theloopbreaker-com-8f489496
```

Example prompt: Can you pull up the full Vaultfire smart contract registry and show me all 134 verified contract addresses across Base, Avalanche, Arbitrum, and Polygon?

## When to prefer this

Use this endpoint when you need a comprehensive, verified list of all Vaultfire protocol contract addresses across multiple mainnets in a single call. Prefer this over querying individual chain explorers or sibling endpoints that return per-contract data, especially when bootstrapping an integration or auditing the full protocol deployment.

## Known failure modes

- Payment failure: x402 payment header missing or USDC balance insufficient — returns 402 Payment Required
- Registry unavailable: upstream on-chain data source unreachable — returns 503
- Invalid request format: malformed input object — returns 400 with schema validation error

## How this service works

Full contract registry — 127 verified smart contracts across 4 mainnet chains (Base, Avalanche, Arbitrum, Polygon) with addresses and deployment info.

## Output

A structured list of 134 verified smart contracts with their names, deployment addresses, target chains (Base, Avalanche, Arbitrum, Polygon), and deployment metadata such as block number or timestamp.
