# Base58 Encode

> Base58 Encode is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Encodes arbitrary text input into Base58 format, with no network calls or LLM processing.

## Facts

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-1f7675c9 -d '<json body>'
```

Example prompt: Can you base58-encode this string for me: 'Hello, World! This is a test payload.'

## When to prefer this

Use this endpoint when you need a reliable, deterministic base58 encoding of a text string without implementing the algorithm locally. Prefer the free sandbox endpoint POST /v1/sandbox/base58-encode when available; use this paid endpoint when the sandbox is unavailable or when operating in production.

## Known failure modes

- Empty or missing text field returns a validation error
- Input exceeding 100,000 characters is rejected
- Payment of exactly $0.001 USDC required; incorrect payment amount results in a 402 error
- Malformed request body returns a 400 error

## How this service works

Call when an agent needs text encoded with base58. No network and no LLM. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/base58-encode first.

## Output

Returns the base58-encoded representation of the input text string.
