## 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 signalforge-studios-creative-check-static-ad-ocr-preflight-9e6e3433 -d '<json body>'
```

Example prompt: Can you run a preflight OCR check on this 1080×1920 ad image and compare it against our approved copy 'Shop now – 50% off today only'? I need to know if any text is low-confidence, too close to the edges, and whether the approved phrases were actually found.

## When to prefer this

Choose this endpoint when you need automated OCR-based preflight validation of static PNG/JPEG ad creatives against a known approved copy script, with word-level bounding boxes and confidence scores. It is specifically suited for pre-submission QA in ad production pipelines where you want to catch missing or misread copy before human review. Prefer it over general-purpose OCR tools when you need copy comparison, edge proximity checking, and advertising-context output in one call.

## Known failure modes

- Image format not PNG or JPEG — endpoint may reject or fail to OCR
- Highly stylized, decorative, or script fonts may result in missed or misread text with low confidence scores
- Approved copy not found due to OCR misread — reported as 'not_found_by_ocr' but text may visually be present
- Very small text or low-resolution images may produce unreliable bounding boxes
- Edge proximity detection may not account for platform-specific safe zone specifications
- No guarantee of ad-platform approval — assessment is an automated aid only

## How this service works

English PNG/JPEG static-ad OCR preflight: compare approved copy, locate low-confidence text and edge proximity, report image dimensions and annotated word boxes. Automated review aid, not a guarantee of spelling, contrast, product fidelity or ad-platform approval.

## Output

Returns a JSON object with image dimensions (width, height), an overall assessment verdict (e.g. 'review'), an array of word annotations each containing a bounding box, text, and OCR confidence score, copy_checks showing whether each approved phrase was found or not found by OCR, and a limitations list noting where human review is still required.
