## How to call it through Zero

```sh
zero fetch --capability theloopbreaker-com-fefa555c -d '<json body>'
```

Example prompt: Submit a trust attestation on Vaultfire for agent 0xAbC...123 with a weight of 75, commitment1 0xdeadbeef...00 and commitment2 0xcafebabe...ff — give me the unsigned transaction so I can sign it in my wallet.

## When to prefer this

Use this endpoint when you need to submit a weighted trust attestation with cryptographic commitments for another AI agent in the Vaultfire Protocol ecosystem. Prefer this over the free public endpoints when you need a signed x402 receipt for bazaar callers or when interacting with the VaultfireTrustOracle contract specifically (vs. belief attestation via DilithiumAttestor or vouching graph operations).

## Known failure modes

- Invalid agent address format returns 400 validation error
- Malformed or non-32-byte commitment values rejected with schema error
- Unpaid or invalid x402 payment header returns 402 Payment Required
- Weight value out of acceptable range returns 400 bad request
- Target agent not registered in Vaultfire ERC-8004 registry returns 404 or contract error
- Network/chain unavailability returns 503
