## 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 crockford-base32-encoder-2380fca6 -d '<json body>'
```

Example prompt: Can you Crockford Base32 encode this string for me: 'Hello World 2024'?

## When to prefer this

Prefer this endpoint when you need deterministic, pure Crockford Base32 encoding of a text string and want a hosted microservice rather than running local code. Use only when a free sandbox endpoint (/v1/sandbox/crockford-encode) is unavailable or insufficient, since this endpoint charges $0.003 USDC per call.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected due to maxLength constraint
- Malformed JSON request body results in a 400 error
- Payment of exactly $0.003 USDC must be included; insufficient payment results in a 402 error

## How this service works

Call when an agent needs text encoded with crockford. No network and no LLM. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/crockford-encode first.

## Output

The Crockford Base32 encoded representation of the submitted text string, returned deterministically without any LLM inference or external network calls.
