## 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-text-analysis-tier-10-8fcc58f4 -d '<json body>'
```

Example prompt: Analyze this text at tier 10 using ONE Engine and give me the structured result: 'The quarterly earnings report exceeded analyst expectations, driven by strong cloud revenue growth and expanding margins in the enterprise segment.'

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call text analysis without a subscription, especially in agentic pipelines that use x402 micropayments on Base. Suitable when you want tier-10 depth of analysis and can tolerate tier-dependent output variability. Prefer over subscription NLP APIs when cost-per-call economics matter for low-volume or sporadic use.

## Known failure modes

- Payment failure if USDC balance insufficient or x402 header malformed
- Empty or missing 'text' field causes malformed request
- Text too long may exceed processing limits
- Tier-specific model unavailable returns error or degraded result
- Network timeout from Cloudflare Worker cold start

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object containing a 'tier' field (value 10) and a 'result' field with tier-dependent text analysis output, which may include classifications, extracted entities, scores, or other NLP-derived insights depending on what the tier 10 model produces.
