## 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 nova-web-research-596d0b7d -d '<json body>'
```

Example prompt: Research these three URLs — https://example.com/ai-report, https://techsite.com/llm-overview, https://news.com/ml-trends — and pull out everything relevant to 'large language model adoption in enterprise software'.

## When to prefer this

Choose this endpoint when you have a specific set of URLs you want to research against a defined query — it is ideal for deterministic, targeted web research rather than open-ended search. Prefer it over general search APIs when you already know which sources to consult and need structured extraction of relevant content from those pages. Best suited for agents doing due diligence, competitive research, or content aggregation from known URLs.

## Known failure modes

- URLs that are paywalled or require authentication return in the 'failed' count with no content
- Malformed or unreachable URLs increment the failed counter and are excluded from sources
- Exceeding 10 URLs in the array causes a validation error
- Missing required 'query' or 'urls' fields results in a 400-level error
- Payment failure via x402 protocol blocks the request before processing

## How this service works

Machine-facing pay-per-call utility services using x402 on Base with USDC.

## Output
