## 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-encoding-pack-tier-1-5a822d00 -d '<json body>'
```

Example prompt: Encode the following text using ONE Engine's tier-1 encoding pack: 'Hello world, this is my payload string.'

## When to prefer this

Choose this endpoint when you need a cheap, fast, stateless text encoding or transformation utility for autonomous agent pipelines and are already using x402 micropayments on Base. Ideal for high-frequency, low-cost encoding tasks where $0.0007 USDC per call is acceptable and Tier 1 processing quality meets your needs.

## Known failure modes

- Empty or missing 'text' field returns an error or empty result
- Payment failure on x402 Base network prevents API access
- Malformed JSON body results in a 400 Bad Request
- Text exceeding length limits may be rejected or truncated
- Network timeout on Cloudflare Workers edge node
