## 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 cross-shard-state-sync-mcp-5745c5cc -d '<json body>'
```

Example prompt: Sync this state payload across all shards to make sure every partition is up to date with the latest data.

## When to prefer this

Choose this endpoint when you need to synchronize or propagate state changes across distributed shards in a single API call, especially in multi-partition architectures where consistency across boundaries is required. Best suited for scenarios where you have a serialized state payload ready to broadcast.

## Known failure modes

- Malformed or missing data field returns a 400-level error
- Shard unavailability may cause partial sync failures
- Network timeouts between shards may result in incomplete propagation
- Conflicting state versions may trigger a conflict error requiring manual resolution
- Payment failure (402) if USDC balance is insufficient

## 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 result confirming whether the cross-shard state synchronization was accepted and applied, potentially including sync status, affected shard identifiers, or error details if consistency could not be achieved.
