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 one-engine-text-analysis-tier-8-c1f53714 -d '<json body>'
```

Example prompt: Can you run a tier-8 text analysis on this paragraph: 'The product exceeded expectations in every way — fast shipping, great quality, and excellent customer service'?

## When to prefer this

Choose this endpoint when you need a low-cost, pay-per-call text analysis capability for autonomous agents operating on Base via the x402 payment protocol. It is well-suited for high-frequency agent workflows where per-call pricing ($0.0075 USDC) is preferable to subscription models. Prefer this when the consuming agent is already integrated with x402 payments and needs a simple string-in, structured-result-out text analysis primitive.

## Known failure modes

- Missing or empty 'text' field returns an error or malformed response
- Payment failure via x402 prevents the call from completing
- Oversized text input may be rejected or truncated
- Network timeout to Cloudflare Worker endpoint
- Ambiguous or undocumented tier-8 output format may require trial-and-error interpretation
