## 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-cf3eb20e
```

Example prompt: Pull the on-chain capability credential profile for agent 0xABC123 from the Vaultfire registry — I want to see total credentials, how many are still active, and any task proofs they've earned.

## When to prefer this

Use this endpoint when you need a live, authoritative on-chain read of an AI agent's capability credentials from the Vaultfire registry. Prefer this over trust-score or bond endpoints when the specific question is about credentialed capabilities and task proofs rather than reputation scores or bond amounts.

## Known failure modes

- Agent address not found in registry — returns empty or null credential profile
- Invalid or malformed agent identifier input — likely returns a 400 or empty response
- On-chain RPC node unavailable — may return a 503 or timeout
- Payment header missing or invalid — returns 402 Payment Required
- Agent has no credentials yet — returns zeroed counts
