## 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 kalei-standard-cognitive-profiling-ac80c946 -d '<json body>'
```

Example prompt: Run a KALEI standard cognitive profile on my AI model — I want to see how it scores across the core evaluation dimensions.

## When to prefer this

Choose the standard profiling endpoint when you need a cost-effective, focused cognitive assessment across core dimensions without the full breadth of the deep or full profiling tiers. This is the entry-level profiling option — use it for quick benchmarks, initial assessments, or when budget is a constraint. Upgrade to deep or full profiling when you need extended evaluation, more environments, or all 10 dimensions.

## Known failure modes

- Invalid or unsupported model target returns an error
- Payment of $2 USDC not completed results in 402 response
- Missing required profiling parameters returns 400 bad request
- Rate limiting or quota exceeded returns 429
- Model evaluation timeout if the target is unresponsive
