## 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-text-summarizer-f0a4c9e9 -d '<json body>'
```

Example prompt: Can you summarize this earnings report in bullet points: '[paste text here]'? I want the key findings broken out clearly.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.002 USDC), pay-per-call text summarization with a choice of output style (brief, detailed, or bullets) and don't want to provision a dedicated NLP service. Especially useful for financial document summarization within an agentic pipeline that already uses x402/USDC on Base for micropayments.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Invalid 'style' enum value (anything outside brief/detailed/bullets) causes a 400 error
- Very long input text may hit token limits or timeouts
- Payment failure via x402 protocol blocks the call with a 402 response
- Service unavailability on the Render host returns a 5xx error

## How this service works

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

## Output

A JSON object containing a 'summary' field with the condensed text and a 'source' field identifying the NEXUS service. The summary is formatted according to the requested style: a short paragraph for 'brief', an expanded narrative for 'detailed', or a list of key points for 'bullets'.
