Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 ddg-summarize-d1c274d0 -d '<json body>'
```

Example prompt: Can you summarize this article for me? Here's the full text: 'Central banks worldwide are raising interest rates in response to persistent inflation, with the Fed signaling at least two more hikes this year, impacting mortgage rates and consumer borrowing costs significantly across all major markets.'

## When to prefer this

Choose this endpoint when you need a cost-effective, microtransaction-priced ($0.005 USDC) summarization service that accepts x402 payment natively, making it ideal for AI agents operating in autonomous crypto-payment pipelines. Prefer this over free-tier LLM APIs when you need a bounded, pay-per-use artifact with no subscription overhead, or when your agent already operates on x402 multi-chain USDC payment rails.

## Known failure modes

- Payment not settled or x402 header missing — returns 402 Payment Required
- Malformed request body or missing required fields (input, output) — returns 400 Bad Request
- Content too long or unsupported body type — may return 422 or 400
- Provider environment unavailable — returns 500 Internal Server Error
- Empty or null body text submitted — may return empty or error response
