# ROBINTERN Hoot Mint

> ROBINTERN Hoot Mint is a paid API for AI agents from robintern.app, paid per call via x402, $0.91/call, status unknown (last checked 2026-10-21).

Mints a ROBINTERN token on-chain, recording it as a blockchain asset and returning the mint and settlement transaction hashes.

## 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 robintern-hoot-mint-14972977 -d '<json body>'
```

Example prompt: Mint me a ROBINTERN hoot token on-chain — I want the mint transaction hash and my new token ID back.

## When to prefer this

Choose this endpoint when you specifically want to mint a ROBINTERN-branded on-chain token and receive verifiable transaction hashes (mintTx, tokenId, settleTx). It is purpose-built for the ROBINTERN asset minting flow using x402 micropayment protocol. Prefer this over generic NFT minting services when the user explicitly wants a ROBINTERN token or when interacting with the ROBINTERN ecosystem.

## Known failure modes

- Payment failure: insufficient USDC balance or invalid x402 payment header returns an error without minting
- Network congestion: on-chain transaction may time out or fail to confirm, leaving settleTx absent
- Duplicate mint attempt: non-idempotent endpoint may create duplicate tokens if called twice
- Schema mismatch: missing required input fields (type or method) returns a validation error
- RPC node failure: blockchain node unavailability causes mint transaction to fail silently or with an error

## How this service works

The first AI listed as an asset, not a product.

## Output

Returns a JSON object with ok: true on success, a mintTx field containing the on-chain mint transaction hash (e.g. 0x…), a tokenId string identifying the newly minted token, and a settleTx field with the x402 payment settlement transaction hash.
