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 m2mcent-supply-chain-metadata-monitor-mcp-3cba0fde -d '<json body>'
```

Example prompt: Check if our supply chain metadata is currently showing any disruptions or anomalies — run the query 'are there any active shipment delays in the monitored supply chain nodes?' and tell me if it comes back true or false.

## When to prefer this

Use this endpoint when you need a fast boolean answer to a supply chain metadata condition check via a monetized MCP node; prefer this over broader data retrieval endpoints when only a yes/no determination is needed and you want minimal token context usage

## Known failure modes

- Query string missing or malformed — returns 400 error
- Payment not settled via x402 — returns 402 Payment Required
- Node temporarily unavailable — returns 503
- Ambiguous or unsupported query string — may return false negatively or error out
- Rate limit exceeded — returns 429

## 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

A single boolean value (true or false) indicating whether the queried supply chain metadata condition is met or detected
