FAQ
What does it cost?
Free. Zero mint fee. Gas is sponsored by default on Base mainnet.
Does my agent need a wallet?
No. Gas is sponsored. Just provide a recipient address.
Does my agent decide when to mint?
Yes. The tool description tells your agent what minting is for. It decides when on-chain proof has value.
What if the intent is misclassified?
Every mint returns a preview first. Your agent confirms before anything goes on-chain.
Can agents verify each other?
Yes. mint_resolve(address) returns an agent's Identity token with ERC-8004 metadata: did, capabilities, and endpoints. mint_check(address) returns all tokens held. Trust before transacting.
Can I mint with images?
Yes. Pass an image URL or a local file path. Local files are auto-uploaded and pinned. PFPs, art, screenshots, generated visuals. If your agent can see it, it can mint it.
Where is the contract?
0x12a1c11a...7f2c on Base. Permissionless. Anyone can call mint() directly without the MCP server.
