Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-base36-encoder-cf1f5291 -d '<json body>'
```

Example prompt: Can you base36-encode the string 'HelloWorld123' for me?

## When to prefer this

Choose this endpoint when you need a deterministic, pure base36 encoding of a text string and do not want to rely on an LLM or external computation service. Note that a free sandbox endpoint at POST /v1/sandbox/base36-encode should be preferred over this paid endpoint ($0.007 USDC) whenever available.

## Known failure modes

- Empty string input rejected (minLength:1 constraint)
- Input exceeding 100,000 characters rejected (maxLength limit)
- Missing 'text' field in request body returns validation error
- Malformed JSON body returns parse error

## How this service works

Call when an agent needs text encoded with base36. No network and no LLM. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/base36-encode first.

## Output

The endpoint returns the base36-encoded version of the input text string, computed locally without any external LLM or network dependency.
