## 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 x402-cloud-web-researcher-9be52db8 -d '<json body>'
```

Example prompt: Can you research the current state of solid-state battery technology for EVs — I need a structured summary of recent developments, key players, and timeline estimates?

## When to prefer this

Choose this endpoint when an AI agent needs to gather current, real-time web information on a topic and return it in structured JSON format — especially useful for autonomous research workflows where paying per-call via x402/USDC is acceptable. Prefer this over static knowledge lookups when recency matters, and over general search APIs when structured synthesis is needed rather than raw search results.

## Known failure modes

- Missing or malformed 'input' object returns a 400 validation error
- Payment failure or insufficient USDC balance results in x402 payment required error
- Query too vague or unsupported topic may return empty or low-quality results
- Rate limiting or quota exceeded returns a 429 error
- Network or upstream web access failure may result in partial results or 500 error

## How this service works

Agent-ready x402 APIs for AI video production, audio localization, web research, document extraction, data analysis, and structured JSON transformation.

## Output

Returns a JSON object with a status string, unique request_id, and a result object containing synthesized web research findings. May also include usage metadata, model_used indicating which AI model performed the research, payment confirmation details, and any warnings encountered during processing.
