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 multichain-state-sync-mcp-38e2fd3d -d '<json body>'
```

Example prompt: Sync this state payload across all connected chains: '{"contractAddress":"0xabc123","newState":"active","epoch":42}' — process it now via the multichain state sync endpoint.

## When to prefer this

Choose this endpoint when you need to synchronize or propagate state data across multiple blockchain networks in a single call, especially in multichain DeFi, governance, or smart contract orchestration scenarios where consistency across chains is critical.

## Known failure modes

- Malformed or invalid JSON string in the data field causes processing failure
- Unsupported chain identifiers in the payload result in partial sync errors
- Network congestion on one or more target chains may cause timeouts
- Missing required state fields in the data object lead to validation errors
- Payment not processed or insufficient USDC balance results in 402 error

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a processed response confirming the state synchronization result across connected chains, typically including success status, chain confirmation details, and any propagation metadata.

## Response schema (JSON Schema)
