# AgentShelf Base62 Decode

> AgentShelf Base62 Decode is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Decodes a base62-encoded string back to its original plaintext representation, with no network calls or LLM involved.

## 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-decode-d1f1d930 -d '<json body>'
```

Example prompt: Can you decode this base62 string for me: 'z4PhNX7vuL3xVChQ1m2AB9Yg5AkpQdwyG'? I need the original text it represents.

## When to prefer this

Use this endpoint when you need a deterministic, offline base62 decode operation with no LLM and no network dependency. It is ideal for decoding base62-encoded tokens, identifiers, or payloads in pipelines where consistency and reproducibility matter. Prefer the free sandbox endpoint POST /v1/sandbox/base62-decode first; use this paid endpoint only when the sandbox is unavailable or rate-limited.

## Known failure modes

- Input string contains characters outside the base62 alphabet (0-9, a-z, A-Z) — returns an error
- Input string is empty or exceeds 100,000 character limit — returns a validation error
- Malformed input that cannot be interpreted as valid base62 encoding — returns decode failure

## How this service works

Call when an agent needs text decoded with base62. No network and no LLM. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/base62-decode first.

## Output

The decoded plaintext or original value corresponding to the input base62-encoded string. The response contains the transformed output without any side effects or external calls.
