## 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 agentbit-base58-decoder-21d53271 -d '<json body>'
```

Example prompt: Can you decode this Base58 string for me: '3yZe7d' — I need to know what value it represents?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call Base58 decoding operation with no API key setup. Ideal for agents handling blockchain addresses, cryptocurrency identifiers, or any Base58-encoded data on an ad-hoc basis. Prefer this over self-hosted solutions when you want zero infrastructure overhead.

## Known failure modes

- Invalid Base58 characters in input (e.g. 0, O, I, l) — returns an error
- Empty input string — returns a validation error
- Input is not valid Base58 format — returns a decode error
- Payment failure via x402 — returns 402 status before processing
