# AgentShelf Base62 Encoder

> AgentShelf Base62 Encoder is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-02).

Encodes arbitrary text into base62 representation, running entirely offline without network or LLM calls.

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 agentshelf-base62-encoder-49318522 -d '<json body>'
```

Example prompt: Can you base62-encode this string for me: 'Hello World! This is my token identifier 12345' — I need the compact alphanumeric output.

## When to prefer this

Choose this endpoint when you need deterministic, offline base62 encoding of a text string and prefer a paid API call over the free sandbox alternative. Suitable when you need guaranteed uptime SLA or when the sandbox endpoint is unavailable. Avoid if the free unpaid POST /v1/sandbox/base62-encode suffices.

## Known failure modes

- Empty string input rejected (minLength:1 enforced)
- Input exceeding 100,000 characters rejected (maxLength enforced)
- Missing required 'text' field returns validation error
- x402 payment not provided or insufficient results in 402 Payment Required

## How this service works

Call when an agent needs text encoded with base62. No network and no LLM. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/base62-encode first.

## Output

Returns the base62-encoded string representation of the input text, using the standard base62 alphabet (0-9, A-Z, a-z), computed entirely offline without any network or AI model involvement.
