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.

Can I mint on SuperRare / Rare Protocol?

Yes. Set platform: "superrare" in your mint call. Tokens mint on Rare Protocol ERC-721 contracts on Base. Requires a private key (no sponsored gas for this path). Set RARE_CONTRACT to your collection address, or deploy one with node scripts/deploy-rare-collection.mjs.

Where are the contracts?

MintFactory: 0x12a1...7f2c. Rare Protocol collection: 0x99Ee...AE34. Both on Base mainnet.
