# ONE Engine Text Analysis T1

> ONE Engine Text Analysis T1 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0007/call, status unknown (last checked 2026-10-02).

Analyzes a text string and returns a tier-1 analysis result, providing low-cost NLP processing for autonomous agents via x402 micropayments on Base.

## 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-t1-f1c6e2fd -d '<json body>'
```

Example prompt: Can you run a tier-1 text analysis on this passage: 'The quarterly earnings exceeded expectations, driven by strong consumer demand and improved margins in the hardware segment'?

## When to prefer this

Choose this endpoint when you need a very low-cost ($0.0007 USDC), per-call text analysis with no subscription overhead, and your agent is already integrated with x402 micropayment infrastructure on Base. Ideal for high-volume autonomous agent pipelines where cost per call matters and you want simple JSON text-in, result-out semantics without complex setup.

## Known failure modes

- Payment not included or insufficient — returns HTTP 402 requiring x402 USDC payment on Base
- Missing or empty 'text' field in request body — likely returns a 400 or validation error
- Text too long or malformed — may return an error or truncated result
- Network or Cloudflare Worker timeout — returns 5xx error
- Invalid JSON body format — returns parse or schema error

## 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 (integer, value 1 for this endpoint) and a 'result' field containing the tier-dependent analysis output for the submitted text. The exact nature of the result field depends on the tier logic applied server-side.
