## How to call it through Zero

```sh
zero fetch --capability gateway-spraay-app-75ca92e5

Example prompt: Can you pull the full metadata for Solana asset DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 — I want to see its name, image, attributes, creators, and whether it's a compressed NFT?

## When to prefer this

Choose this endpoint when you need complete, structured DAS-compliant metadata for a specific Solana asset (SPL token or compressed NFT) by its mint/asset address. Prefer this over generic RPC calls when you need normalized metadata including traits, creators, and compression details in a single call.

## Known failure modes

- Invalid or malformed asset ID returns a 400 error
- Asset ID not found on-chain returns a 404 or empty result
- Network or RPC timeout returns a 5xx error
- Missing required 'id' query parameter returns a validation error
- Payment not included or insufficient returns a 402 Payment Required
