## 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 theloopbreaker-com-0d2dd848
```

Example prompt: What's the current USD value of this agent's Vaultfire stake — I need the native token amount, dollar conversion, and the full Chainlink audit trail including feed address and roundId.

## When to prefer this

Use this endpoint when you need a USD-denominated view of an agent's Vaultfire bond that is verifiably backed by Chainlink oracle data, including a full on-chain audit trail. Prefer this over generic balance lookups when you need the Chainlink roundId, feed address, and updatedAt for compliance or trust verification purposes. Best for scenarios where both the stake amount and its USD conversion need to be cryptographically auditable.

## Known failure modes

- Agent address not found in Vaultfire registry — returns empty or zero stake
- Chainlink price feed temporarily unavailable — returns error with feed address and last known roundId
- Unsupported chain — agent bond exists on a chain without a Chainlink feed configured
- Stale price data — updatedAt is beyond acceptable staleness threshold
- Payment header missing or invalid x402 payment — returns 402 Payment Required
- Network RPC error on Base/Avalanche/Polygon — returns upstream node error

## How this service works

Compute an agent's USD-denominated Vaultfire stake by combining Vaultfire's on-chain bond data (real ETH/AVAX/MATIC locked) with Chainlink's decentralized price feeds. Returns native-token stake, USD value, bond activity, and full Chainlink audit trail (feed address, roundId, updatedAt). Unique to Vaultfire × Chainlink.

## Output

Returns the agent's native token stake amount (ETH/AVAX/MATIC), its USD-denominated value computed via Chainlink price feeds, bond activity data, and a full Chainlink audit trail including feed address, roundId, and updatedAt timestamp.
