## 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 stabledesign-asset-update-3aa9df73 -d '<json body>'
```

Example prompt: Update the asset with ID 'asset-abc123' in my StableDesign project — change its name to 'hero-banner-v2' and replace the image with the new file I uploaded.

## When to prefer this

Use this endpoint when you need to modify or replace an existing asset already uploaded to a StableDesign/Canva project, rather than uploading a brand-new asset from scratch. Prefer this over a create endpoint when the asset record already exists and only its content or metadata needs to change.

## Known failure modes

- Asset ID not found — returns 404 if the specified asset does not exist
- Invalid or missing required fields — returns 400 if request body is malformed
- Payment failure — returns 402 if the $0.01 USDC micropayment via x402 is not provided or rejected
- Unauthorized access — returns 401 if the caller lacks permission to modify the asset
- Canva backend error — returns 500 if the underlying Canva API fails to process the update

## How this service works

Pay-per-call Canva design API via MPP micropayments. Create, list, export designs and upload assets.

## Output

Returns a confirmation of the updated asset record including the asset ID, updated metadata fields, asset URL, and current status after the modification is applied.
