## 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 evidence402-web-batch-reader-18c7c7e1 -d '<json body>'
```

Example prompt: Can you fetch the content from these three URLs — https://example.com/report, https://news.org/article, and https://doi.org/10.1038/s41586-021-03819-2 — and extract the main structured data from each, verifying the DOI citation?

## When to prefer this

Choose this endpoint when you need to process multiple URLs in a single call rather than making separate requests per page, especially when DOI citation verification is also needed. It is ideal for research workflows, academic fact-checking, or competitive intelligence gathering where no API key or subscription is required and pay-per-call micropayment via x402 USDC on Base is preferred over subscription models.

## Known failure modes

- URL is not publicly accessible or behind a login wall — page returns empty or error
- DOI does not resolve to a valid publication — citation verification fails
- Rate limiting or server unavailability on target URLs — partial results returned
- x402 payment failure — call is not processed if USDC payment on Base is rejected
- Malformed or unreachable URLs in the batch — those entries return null or error status
- Target page uses heavy JavaScript rendering — content may be incomplete if only static HTML is fetched
