## 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 race-condition-shield-mcp-1b3ecc18 -d '<json body>'
```

Example prompt: Can you run this data payload through the race condition shield to check for any concurrency conflicts or timing vulnerabilities before I process it in my distributed system?

## When to prefer this

Use this endpoint when you need to programmatically detect or guard against race conditions in concurrent workflows, distributed systems, or shared resource access scenarios — especially when integrating into an agentic pipeline that processes payloads before committing them to stateful systems.

## Known failure modes

- Invalid or missing 'data' field returns a 400 Bad Request
- Malformed JSON payload causes processing failure
- Ambiguous or non-deterministic input data may produce inconclusive shield results
- Service unavailability or timeout returns 5xx error
- Payment not received or x402 protocol failure blocks request

## How this service works
