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 vaults-fyi-network-list-aa96c746
```

Example prompt: What blockchain networks does vaults.fyi support? I need the list of all chains including their chain IDs and CAIP identifiers so I can figure out which networks I can use for DeFi yields.

## When to prefer this

Use this endpoint when you need to discover which blockchain networks are supported by vaults.fyi before querying vaults or assets, or when you need canonical chain IDs and CAIP identifiers to use as filter parameters in sibling endpoints.

## Known failure modes

- API returns 402 Payment Required if x402 payment header is missing or insufficient
- Network request timeout if the endpoint is temporarily unavailable
- Empty list if no networks are currently configured
- Malformed response if API versioning mismatch occurs

## How this service works

Retrieves a complete list of supported blockchain networks with their identifiers including network name, chain ID, and CAIP format identifier.

## Output

A list of supported blockchain networks, each with its human-readable name, numeric chain ID, and CAIP-format chain identifier (e.g. eip155:1 for Ethereum mainnet). Used to enumerate valid networks for querying vaults and assets on the platform.
