## 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 24k-labs-ai-content-summarizer-9fe48659 -d '<json body>'
```

Example prompt: Summarize this article for me into key bullet points: 'Large language models have transformed how developers build applications. They enable natural language interfaces, code generation, and automated reasoning at scale. However, challenges around cost, latency, and accuracy remain significant barriers to adoption.'

## When to prefer this

Choose this endpoint when you need a quick, pay-as-you-go text or code summarization without managing API keys or subscriptions. Ideal for agents that need to summarize arbitrary content on demand and can pay per-request in USDC on Base L2. Best when you want bullet-point-style output and don't need fine-grained control over the summarization model.

## Known failure modes

- Payment not provided or insufficient USDC — returns HTTP 402 Payment Required
- Missing required 'code' field — returns 400 Bad Request
- Content too long for model context window — returns 400 or 500 error
- Network or model inference failure — returns 500 Internal Server Error
- Invalid Base L2 payment transaction — payment rejected before processing
