## 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 oblique-markets-batch-url-json-extraction-a7aff9c5 -d '<json body>'
```

Example prompt: Can you extract structured data from these 5 product pages — grab the title, price, and availability from each — and return the results as JSON matching my schema? Here are the URLs: https://shop.example.com/item/1, /item/2, /item/3, /item/4, /item/5.

## When to prefer this

Choose this endpoint when you need to extract structured, schema-validated JSON from multiple public URLs (up to 10) in a single call with parallel isolated execution. Prefer it over single-URL extraction when you have a list of pages to process in one shot, and over generic scraping tools when you need the output to conform to a specific JSON Schema. The built-in idempotency key support makes it safe to retry without re-charging or duplicating work.

## Known failure modes

- URL is not publicly accessible or returns a non-200 response — that item's result will contain an error
- Page content does not contain data matching the supplied JSON Schema — extraction may return null or partial fields
- Batch exceeds 10 items — request rejected with validation error
- Invalid JSON Schema supplied for one or more items — schema compilation failure returned
- Network timeout fetching a URL — that item returns a timeout error
- Idempotency key collision with a prior request that had different inputs — may return prior result or conflict error

## How this service works

Use when an agent needs batch extract. Returns Run up to 10 public URL JSON extractions in isolated ephemeral compute against caller-supplied JSON Schemas with idempotent reconciliation. $0.02.

## Output

An array of up to 10 schema-validated JSON objects, one per input URL-schema pair, each containing the extracted structured data from the respective page. Results are reconciled idempotently if an idempotency_key is supplied, so repeat calls with the same key return the cached result rather than re-running the extractions.
