## 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 exepal-ad-creative-score-batch-896accb6 -d '<json body>'
```

Example prompt: Score these 3 TikTok ad creatives for me — here are the scripts and hooks: Creative 1 hook 'You've been doing it wrong your whole life' script 'Our product fixes X in 30 seconds', Creative 2 hook 'POV: you finally found the fix' script 'Here's why everyone is switching to Y', Creative 3 hook 'This changed everything for me' script 'Z is the only solution that actually works' — tell me which ones are strongest and why.

## When to prefer this

Choose this endpoint when you need to evaluate multiple ad creatives in a single call without setting up accounts or API keys, paying only per use in USDC. Ideal for agents automating creative review pipelines, agencies auditing deliverables at scale, or performance marketers wanting AI scoring before committing ad spend. Prefer this over manual review when speed and cost-per-call economics matter.

## Known failure modes

- Payment not received or insufficient USDC — 402 response
- More than 10 creatives submitted — validation error
- Missing required script field for one or more creatives
- Unsupported platform value provided
- Malformed JSON body — 400 error
- Temporary service unavailability — 5xx error
