## 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 distributed-lock-service-mcp-8c5ea890 -d '<json body>'
```

Example prompt: I need to acquire a distributed lock on the 'order-processing-queue' resource before my agents start updating it — can you request the lock and let me know once it's been granted?

## When to prefer this

Choose this endpoint when you need to coordinate concurrent access to shared resources across multiple distributed agents, workers, or services. Ideal for preventing race conditions, double-processing, or conflicting writes in multi-agent workflows where no other synchronization primitive is available.

## Known failure modes

- Lock already held by another process — returns a conflict or busy status
- Invalid or malformed lock request data — returns a validation error
- Lock timeout exceeded before acquisition — returns a timeout error
- Service unavailable or network error — returns 5xx response
- Attempting to release a lock not owned by the caller — returns authorization 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 JSON response indicating whether the lock was successfully acquired, along with a lock token or identifier and expiry information. On failure, indicates that the lock is already held by another process.
