## 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-encoder-8d7c7597 -d '<json body>'
```

Example prompt: Can you Base58-encode this string for me: '00010966776006953d5567439e5e39f86a0d273beed61967f6'?

## When to prefer this

Use this endpoint when you need a pay-per-call, no-signup Base58 encoding service accessible directly by an AI agent without API key management. Ideal for infrequent, on-demand encoding tasks within an agentic workflow where simplicity and zero-configuration matter.

## Known failure modes

- Empty or missing 'input' field returns an error
- Malformed JSON request body causes a 400-level error
- Payment failure via x402 protocol prevents the call from completing
- Very large input strings may be rejected or time out

## How this service works

Base58-encode bytes with the Bitcoin/Solana alphabet (no 0, O, I, l) — the encoding behind BTC and Solana addresses.

## Output

A JSON object containing the Base58-encoded representation of the provided input string, ready to use in blockchain, crypto, or any application requiring Base58 encoding.
