## 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 nexus-agent-services-financial-search-f96b274b
```

Example prompt: Search NEXUS for a financial summary on Apple Inc. — I want to know the latest key financial data and any relevant market context.

## When to prefer this

Use this endpoint when you need a quick, AI-summarized financial data result for a specific query and are willing to pay $0.02 USDC per call via x402 on Base; prefer this over free alternatives when you need structured, summarized output rather than raw data or when integrating micropayment-based API calls into an autonomous agent workflow.

## Known failure modes

- Missing required query parameter 'q' returns a validation error
- Insufficient USDC balance or failed x402 payment results in 402 Payment Required
- Service unavailable on Render free tier cold-start causes timeout
- Empty or ambiguous query may return a generic or low-quality AI summary
- Rate limiting may occur under high call volume

## How this service works
