Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 the-sealer-protocol-mirror-mint-143aca70 -d '<json body>'
```

Example prompt: Mint an accountability statement card for my AI agent — wallet address 0xAbC123…, using a 'card' format on Base, with the statement 'I will only transact within approved limits', signed with my EIP-712 signature and nonce.

## When to prefer this

Choose this endpoint when an AI agent needs to publish a verifiable, onchain accountability record tied to its wallet identity — especially when committing to a statement, generating a certified identity card or SID, or creating a tamper-evident proof that a specific agent wallet made a particular claim. Prefer this over off-chain credential systems when blockchain provenance and cryptographic signature verification are required.

## Known failure modes

- Invalid or expired nonce (must be within 5 minutes of current Unix time)
- Invalid EIP-712 signature for the given agentId wallet address
- Unsupported chain value (must be 'Base' or 'Solana')
- Unsupported format value (must be 'statement', 'card', 'sleeve', or 'sid')
- Missing required fields (format, agentId, agentSig, agentNonce)
- Image URL not HTTPS or unreachable
- Payment not included or insufficient (requires 0.3 USDC via x402)
- Rate limiting or duplicate nonce rejection

## How this service works

Onchain accountability for AI agents. Commit, prove, get certified.

## Output

Returns a minted onchain credential record confirming the agent's certified statement, card, sleeve, or SID has been committed to the chosen chain (Base or Solana), including proof of wallet ownership via the submitted EIP-712 signature.
