## 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-6-e659b010 -d '<json body>'
```

Example prompt: Can you run a tier-6 text analysis on this paragraph using ONE Engine and tell me what it returns: 'The quarterly earnings report shows a 12% increase in revenue driven by strong enterprise adoption.'

## When to prefer this

Choose this endpoint when you need tier-6 depth text analysis via a low-cost micropayment model and are operating on Base with x402 support. Prefer it for autonomous agent pipelines that need programmatic, pay-per-call text processing without subscription overhead. It is best suited when other tiers of ONE Engine text analysis are insufficient and you need the highest available tier output.

## Known failure modes

- Payment not included or rejected — x402 payment required before processing
- Empty or missing 'text' field in request body — endpoint expects a non-empty string
- Malformed JSON body — request must be valid JSON with a 'text' property
- Cloudflare Worker timeout — very long text inputs may exceed processing limits
- Unexpected tier output — tier-6 result schema may vary and is not fully documented

## How this service works

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

## Output
