## 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-4bec136b
```

Example prompt: Pull up the Vaultfire vouching graph for agent 0xABCD1234 — I want to see how many vouches they've given and received, their total stake, any slash history, their bond partnerships, and the integrity composite score.

## When to prefer this

Use this endpoint when you need a comprehensive view of an agent's social trust layer — specifically the vouch graph and bond partnership data — rather than just a raw trust score or registration status. Prefer this over the basic trust profile lookup when you need slash history, integrity composite, or a breakdown of directional vouch counts.

## Known failure modes

- Agent not found or not registered in ERC-8004 registry — returns empty or 404-equivalent response
- Invalid or malformed agent address input — returns validation error
- On-chain data unavailable or node timeout — returns service error
- Payment header missing or insufficient ($0.02 USDC required) — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests

## How this service works

Vouching graph slice for an agent — counts of vouches given/received, total stake, slash record, bond partnerships, plus an integrity composite.

## Output

Returns a vouching graph slice for the specified agent including: counts of vouches given and received, total staked amount, slash record history, active bond partnerships, and a computed integrity composite score summarizing the agent's on-chain trust posture.
