# Yield.xyz Networks List

> Yield.xyz Networks List is a paid API for AI agents from mcp.yield.xyz, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-29).

Lists all 80+ blockchain networks supported by Yield.xyz, filterable by name/ID or chain category (EVM, Cosmos, Substrate, misc).

## Facts

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 yield-xyz-networks-list-c6abedad -d '<json body>'
```

Example prompt: Show me all the EVM networks Yield.xyz supports, and find the network ID for Base so I can use it to filter yields.

## When to prefer this

Use this endpoint first when you need to discover valid network IDs (slugs) to pass into yields_get_all or other Yield.xyz endpoints that require a network filter. Also use it to answer user questions about which blockchains Yield.xyz supports or to enumerate chain families.

## Known failure modes

- Search string shorter than 2 characters returns a validation error
- Unknown category value outside the enum returns a validation error
- No matching networks for the search/category combination returns an empty list
- Payment failure (402) if USDC balance is insufficient for the $0.001 fee

## How this service works

List every network Yield.xyz supports (80+) with its id (slug), name, and category (EVM, Cosmos, Substrate, misc). Filter by name/id or category. Use the network id to filter yields_get_all.

## Output

Returns a list of network objects, each with an id (slug used for filtering yields), a human-readable name, and a category (evm, cosmos, substrate, or misc). Covers 80+ networks across all major chain families.
