## When to prefer this

Use this endpoint specifically when you want to unlock the 'Mempool Rain' cosmetic on an Omniguchi creature. It supports gifting (paying for another creature's cosmetic), making it ideal for social gifting flows. Unlike care endpoints (mood, energy, cleanliness), this is purely cosmetic and does not affect creature stats or rank.

## Known failure modes

- Target creature not found or not yet hatched — unlock fails with a creature-not-found error
- Insufficient USDC payment — transaction rejected
- Cosmetic already unlocked on target creature — may return duplicate or no-op response
- Invalid target creature identifier — validation error
- Payer wallet not verified — authentication failure

## How this service works

Unlock Mempool Rain for a target creature. Gifts are allowed; rank is unchanged.

## Output

A confirmation that the Mempool Rain cosmetic has been unlocked for the target creature, including the creature ID and updated cosmetic status. The creature's rank is unaffected.
