# Base58 Encode/Decode

> Base58 Encode/Decode is a paid API for AI agents from conclavex402p04.pythonanywhere.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-18).

Encodes bytes or hex strings to Base58 format (Solana-style) or decodes Base58 strings back to their original representation.

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 base58-encode-decode-f8c642b6 -d '<json body>'
```

Example prompt: Can you base58-encode this hex string for me: 04a5b3c7d9e1f2a0? I need it in Solana-style base58 format.

## When to prefer this

Choose this endpoint when you need Solana-compatible (Bitcoin-style, no padding zeros) Base58 encoding or decoding of arbitrary hex or byte data. Prefer this over generic encoding libraries when operating in a blockchain/Solana context where the exact Base58 alphabet and checksum behavior matters, or when you need a pay-per-call hosted service without managing local dependencies.

## Known failure modes

- Invalid hex string input returns an error
- Malformed Base58 input during decode (non-base58 characters) causes a decode failure
- Missing required 'input' body field returns a validation error
- Incorrect bodyType or method returns a 400-style error

## How this service works

Base58 encode or decode bytes/hex (Solana-style base58).

## Output

Returns a JSON object with a 'base58' field containing the Base58-encoded string (for encode operations) or the decoded output (for decode operations), e.g. {"base58": "6h8cQN"}.
