## 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 vaults-fyi-asset-list-fa708e7b
```

Example prompt: Show me the first 50 supported assets on vaults.fyi for the Base network, including their contract addresses and symbols.

## When to prefer this

Use this endpoint when you need to discover which tokens/assets are supported by vaults.fyi on a specific network, retrieve asset contract addresses or decimals for integration, or build a filtered asset picker UI. Prefer this over the vaults endpoint when you only need asset-level metadata rather than vault performance data.

## Known failure modes

- Invalid or unsupported network name returns an error or empty result
- Page number out of range returns empty data set
- perPage exceeding maximum of 5000 returns a validation error
- Network specified as CAIP ID with incorrect format may not resolve
- Payment not included or insufficient (x402 payment required at $0.002 USDC per call)

## How this service works

Retrieves a filtered list of supported assets with their metadata including address, symbol, name, decimals, and network information.

## Output

A paginated list of supported asset objects, each containing the asset's contract address, symbol (e.g. USDC), human-readable name, decimal precision, and associated blockchain network identifiers (both friendly name and CAIP format).
