# ONE Engine Text Analysis Tier 7

> ONE Engine Text Analysis Tier 7 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Performs tier-7 text analysis on a given string, returning a structured result via a pay-per-call x402 API on Base.

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-7-c0c51991 -d '<json body>'
```

Example prompt: Can you run the tier-7 text analysis on this passage: 'The quarterly earnings exceeded expectations, with revenue up 23% year-over-year'?

## When to prefer this

Choose this endpoint when you need low-cost, pay-per-call text analysis via crypto micropayment (x402/USDC on Base) and specifically require tier-7 processing logic. It is suitable for autonomous agents that need to analyze text programmatically without a subscription, especially in high-volume or cost-sensitive pipelines where per-call pricing is preferred over flat-rate plans.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Payment failure via x402 prevents execution
- Cloudflare Worker timeout for very long text inputs
- Ambiguous or malformed JSON body returns a 400-level error
- No response schema guarantees beyond the example structure — result content may vary

## How this service works

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

## Output

Returns a JSON object with a 'tier' field (value 7, confirming which analysis tier was applied) and a 'result' field containing the tier-dependent analysis output — the exact format of 'result' depends on the tier's logic and may include classifications, scores, or extracted data.
