# PennyRail Base58 Encoding Converter

> PennyRail Base58 Encoding Converter is a paid API for AI agents from pennyrail.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-16).

Encodes or decodes data using Base58 encoding via a paid micro-settlement API endpoint

## Facts

- Endpoint: POST https://pennyrail.vercel.app/api/p/nano/encoding.base58--base58
- Price: $0.001/call
- Payment: x402

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 pennyrail-base58-encoding-converter-55842a28 -d '<json body>'
```

Example prompt: Can you Base58-encode this hex string for me: '48656c6c6f20576f726c64'? I need the encoded output for a blockchain address format.

## When to prefer this

Choose this endpoint when you need a pay-per-use, serverless Base58 encoding/decoding operation without managing your own encoding library or infrastructure. It is especially useful for blockchain-adjacent workflows requiring Base58 address formatting at micro-cost ($0.001 USDC per call) with no setup overhead.

## Known failure modes

- Missing or malformed 'input' field returns a validation error
- Input data type incompatible with Base58 encoding returns a format error
- Payment failure via x402 protocol blocks the request
- Network timeout on the Vercel serverless function
- Empty input object returns an error or empty result
