## 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 billitright-co-casa-performance-validation-09f22f8d -d '<json body>'
```

Example prompt: Run a CASA performance validation on https://api.myservice.com/v1/health to check if it stays available and responsive under normal load and traffic surges — use REST binding and a GET method.

## When to prefer this

Choose this endpoint when you need a CASA-standard performance validation specifically focused on service availability, latency, and stability under varied load conditions — not just functional correctness. Prefer this over general uptime monitors when you need structured cybersecurity assessment evidence for compliance reporting or third-party vetting.

## Known failure modes

- Target URL is unreachable or returns non-2xx responses causing assessment failure
- Invalid or malformed target_url format causing schema validation error
- Target service blocks automated test traffic via rate limiting or IP filtering
- Assessment timeout if target endpoint response times are extremely high
- Missing required fields (type, method, bodyType) causing request rejection
- Access token invalid or expired when testing authenticated endpoints

## How this service works

Password - CASA Cybersecurity Assessment - Assesses service availability, responsiveness, and stability under normal load, sustained traffic, and request surges. It verifies whether the endpoint remains usable without excessive latency, failures, or degradation.

## Output

Returns a structured performance assessment report indicating whether the target endpoint maintained acceptable availability and responsiveness under normal load, sustained traffic, and request surges, along with details on latency, failure rates, and any degradation observed.
