## 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 pagos-andreax-dev-web-research-investigator-783e9e44
```

Example prompt: Can you research the latest developments in quantum computing for me and summarize what you find, with links to the sources?

## When to prefer this

Choose this endpoint when an AI agent needs current, sourced information from the web rather than relying on its training data. Ideal for queries requiring up-to-date facts, recent news, or verifiable references. Prefer this over static knowledge retrieval when citations and source URLs are required, or when freshness of information is critical. At $0.02 per call it is cost-effective for per-query research tasks in agentic pipelines.

## Known failure modes

- Empty or overly broad topic may return generic or low-quality synthesis
- Topic that yields no web results may return an empty or partial response
- Rate limiting or payment failure (402) if USDC payment is not properly configured
- Very niche or obscure topics may return fewer cited sources than expected
- Network timeouts if web research takes longer than the response window

## How this service works

Investiga un tema en la web y devuelve una síntesis con fuentes citadas (títulos + URLs). Úsalo para research pagado por consulta cuando un agente necesita información actual con fuentes. input=tema a investigar.

## Output

A synthesized textual summary of the researched topic drawn from current web sources, accompanied by a list of cited sources including their titles and URLs, giving the agent both the distilled information and traceable references.
