## 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 autonomy-api-network-text-diff-2ec52c14 -d '<json body>'
```

Example prompt: Compare these two versions of the product description and tell me exactly what was added or removed: before: 'Free shipping on orders over $50. Returns accepted within 30 days.' after: 'Free shipping on all orders. No returns accepted.'

## When to prefer this

Use this endpoint when you need to programmatically compare two versions of text or HTML content and get structured output identifying exactly what changed — ideal for change detection pipelines, content monitoring, document revision tracking, or auditing webpage updates. Prefer it over manual diffing or generic LLM comparisons when you need precise, structured addition/removal output rather than a prose summary.

## Known failure modes

- Missing 'before' or 'after' field returns a 400 validation error
- Extremely large text payloads may time out or exceed size limits
- Non-UTF-8 encoded content may cause parsing errors
- Payment failure via x402 protocol returns 402 Payment Required

## How this service works

## Output

A structured response containing the additions (new content in 'after' not present in 'before'), removals (content in 'before' not present in 'after'), and a similarity score reflecting how close the two inputs are.
