## 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 agentshelf-ascii85-encoder-9948b225 -d '<json body>'
```

Example prompt: Can you ASCII85-encode this text for me: 'Hello, World! This needs to go into a PostScript file.'

## When to prefer this

Choose this endpoint when you need deterministic, pure-function ASCII85 (Base85) encoding of a text string without any LLM involvement or external network calls. Prefer this paid endpoint when the free sandbox version (/v1/sandbox/ascii85-encode) is unavailable or rate-limited. This is the right choice for workflows embedding text into PostScript, PDF streams, or legacy protocols requiring Base85-encoded payloads.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Input exceeding 100,000 characters is rejected
- Malformed JSON request body returns a 400 error
- Network or server unavailability returns a 5xx error
- Insufficient USDC balance or payment failure blocks the request

## How this service works

Call when an agent needs text encoded with ascii85. No network and no LLM. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/ascii85-encode first.

## Output

Returns the ASCII85-encoded representation of the provided input text string, suitable for embedding in PostScript, PDF, or other contexts that require Base85 encoding.
