## 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-data-execution-ee1ad6f4 -d '<json body>'
```

Example prompt: Use NEXUS to look up the current market cap and 24-hour price change for Bitcoin and give me the result.

## When to prefer this

Prefer this endpoint when you need on-demand financial data with micropayment billing and no subscription commitment, especially in agent workflows that require pay-per-use economics via x402 USDC on Base. Best suited for agents that need flexible, natural-language-driven financial queries without pre-negotiated API keys.

## Known failure modes

- Insufficient USDC balance for x402 micropayment — payment fails before task executes
- Ambiguous or unsupported task description — may return a generic or incomplete result
- Service unavailable on Render.com free tier due to cold start or downtime
- Task string too vague to map to a specific financial data query — result may be unhelpful
- Rate limiting or network timeout on streamable HTTP connection

## How this service works

Pay-per-call financial data. Streamable HTTP MCP. x402 USDC on Base. Not financial advice.

## Output

Returns a JSON object with a 'result' field containing the completed task output (financial data, metrics, or analysis) and a 'source' field attributed to NEXUS. The exact structure of the result depends on the task provided.
