## 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 minecraft-player-profile-lookup-api-cfd72ab5
```

Example prompt: Can you look up the Minecraft player profile for the username 'Notch' and give me their UUID and skin URL?

## When to prefer this

Use this endpoint when you need to resolve a Minecraft username to a UUID, retrieve a player's current skin or cape, or verify that a Minecraft account exists — especially in agent or automation contexts where you want micropayment-per-call pricing with no API signup required.

## Known failure modes

- Username not found returns found:false with null skin/cape fields
- Invalid or malformed username may return an error or found:false
- Rate limiting may occur on high-frequency calls
- UUID-based lookup may fail if the UUID format is incorrect

## How this service works

Modrinth mod compatibility checks for agents and modpack tools. 0.01 USDC per call via x402, no signup.

## Output

A JSON object containing the player's UUID, canonical username, skin texture URL, cape URL (or null if none), skin model type ('classic' or 'slim'), and a boolean 'found' flag indicating whether the account exists.
