## 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-6-e8704c0e -d '<json body>'
```

Example prompt: Encode the following text using the ONE Engine encoding pack at tier 6: 'Hello world, this is my payload for the agent pipeline.'

## When to prefer this

Choose this endpoint when you need a low-cost, pay-per-call text encoding or transformation at tier 6 specifically, and are already operating within an x402-compatible payments stack on Base. Ideal for autonomous agents that need lightweight, metered text processing without subscription overhead.

## Known failure modes

- Missing or empty 'text' field returns an error or empty result
- Insufficient USDC balance via x402 causes payment failure and request rejection
- Malformed JSON body causes a 400-level error
- Cloudflare Worker timeout for very large text inputs
- Network errors or worker downtime returning 5xx responses
