## 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 one-engine-t5-text-analysis-7207fceb -d '<json body>'
```

Example prompt: Analyze this text using the ONE Engine T5 text analysis API and tell me what it returns: 'The quarterly earnings report shows a significant uptick in recurring revenue despite headwinds in the SMB segment.'

## When to prefer this

Choose this endpoint when you need a low-cost ($0.0025 USDC), pay-per-call T5-based text analysis that settles on Base via x402, especially in autonomous agent workflows where cost-per-inference matters and you want a simple text-in / structured-result-out API without managing model infrastructure.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Insufficient USDC payment via x402 results in a 402 Payment Required response
- Text that is too long may be truncated or rejected
- Ambiguous or non-English text may yield low-confidence or unexpected tier output
- Network timeout on the Cloudflare Worker edge may return a 503

## How this service works
