Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 korus-music-license-purchase-06e4caec -d '<json body>'
```

Example prompt: I want to license the KORUS track with listing ID 'abc-123' so I can remix its official stems — go ahead and purchase that license for me using a fresh idempotency key.

## When to prefer this

Use this endpoint when an agent needs to programmatically purchase a music license on the KORUS platform for a specific listing, receiving a verifiable on-chain settlement and a license key. Prefer this over generic payment endpoints when the goal is specifically to unlock KORUS music content (stems, songs, remix rights) with idempotent USDC payment on the Base network.

## Known failure modes

- Duplicate idempotencyKey with conflicting parameters returns an error or replays the original response
- Invalid or non-existent listingId returns a not-found error
- Payment failure or insufficient USDC balance results in payment status indicating failure
- Network congestion on Base blockchain may delay settlement confirmation
- Missing required idempotencyKey field returns a 400 validation error

## How this service works

KORUS is an interactive remixing platform where fans, artists, and communities generate new songs, remix official stems, and build shared musical moments in real time.

## Output

Returns an order object (with order ID, listing ID, amount, currency, status, and creation timestamp), a payment object (with status and optional redirect URL), a settlement object (with blockchain transaction hash, network, payer address, amount, and currency), and optionally a license object containing the license key — all wrapped under apiVersion v1.
