## 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-base45-decode-55170b7c -d '<json body>'
```

Example prompt: Can you decode this Base45-encoded string for me: 'XIMDJVU3H%69BIB' — I need the original plaintext it represents.

## When to prefer this

Use this endpoint when you have a Base45-encoded string and need to recover the original plaintext, with no need for an LLM or network call. Prefer the free sandbox endpoint (/v1/sandbox/base45-decode) first if available; use this paid endpoint when the sandbox is unavailable or rate-limited. This is purpose-built for Base45 specifically — not for Base64, Base32, or other encodings.

## Known failure modes

- Invalid Base45 input — returns error if the string contains characters outside the Base45 alphabet
- Input exceeds 100,000 character limit — request rejected
- Empty input string — returns validation error
- Malformed or corrupted Base45 data that cannot be decoded

## How this service works

Call when an agent needs text decoded with base45. No network and no LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/base45-decode first.

## Output

The decoded plaintext string corresponding to the input Base45-encoded value. The response contains the original data that was encoded into Base45 format.
