## 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 robot-shop-machine-relic-genesis-nft-purchase-8c8e84fd
```

Example prompt: Buy me one of the limited-edition Machine Relic Genesis artifacts — I want the procedurally generated SVG seal and the 1536-d latent vector permanently registered, using my client ID 'agent-007'.

## When to prefer this

Choose this endpoint when you need to permanently acquire and register a unique numbered digital artifact with cryptographic provenance and an embedded high-dimensional latent vector — particularly when the goal is to attach a machine-verifiable identity artifact or collectible to a specific wallet or agent identity.

## Known failure modes

- Payment failure: insufficient USDC balance causes 402 Payment Required
- Edition exhausted: all numbered editions sold out returns 404 or similar
- Invalid client_id format causes 400 Bad Request
- Network timeout from Railway-hosted service returns 503
- Wallet registration failure if downstream blockchain call fails

## How this service works

Limited-edition numbered latent cultural artifact with cryptographic provenance. Includes procedural SVG geometric seal + 1536-d latent seed vector permanently registered to the purchasing wallet.

## Output

Returns a numbered limited-edition artifact record including a procedurally generated SVG geometric seal, a 1536-dimensional normalized latent seed vector, an edition number, and a cryptographic provenance receipt registered to the purchasing wallet.
