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-decentralized-storage-indexer-mcp-d5d6b627 -d '<json body>'
```

Example prompt: Can you check if the CID 'QmXoypizjW3WknFiJnKLwHCnL72vedxjQkDDP1mXWo6uco' is indexed in the M2MCent decentralized storage indexer?

## When to prefer this

Use this endpoint when you need to verify whether a specific decentralized storage CID is tracked and indexed in the M2MCent MCP node network, particularly before serving or sharing decentralized content to end users. Prefer this over manual IPFS gateway checks when you need a programmatic boolean signal integrated into an automated workflow.

## Known failure modes

- Missing or invalid CID returns an error or false indexStatus
- CID not yet propagated to the index returns false even if recently uploaded
- Malformed CID string may cause a validation error
- Payment failure via x402 prevents the call from completing
- Network or node unavailability may cause timeouts

## 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 JSON object containing a single boolean field 'indexStatus' — true if the provided CID is present and indexed in the M2MCent decentralized storage network, false if it is not found or not yet indexed.
