## 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 x402-outpimp-com-base64-decoder-fac2d0d6 -d '<json body>'
```

Example prompt: Can you decode this base64 string for me: 'SGVsbG8sIFdvcmxkIQ=='? I need the original plain text.

## When to prefer this

Prefer this endpoint when an AI agent needs to reliably decode base64 strings without the padding or charset errors that LLMs commonly make when attempting to decode base64 manually. Ideal for pipelines that frequently encounter base64-encoded fields in API responses, config files, or data blobs.

## Known failure modes

- 400 if 'text' field is missing from the request body
- 400 if 'text' is not a string type
- 400 if the input is not valid base64 (e.g. illegal characters, wrong padding)
- Payment failure if USDC balance is insufficient for the $0.01 per-call fee

## How this service works

Base64 decoder API. Decodes a base64 string back to UTF-8 text instantly and correctly, avoiding the padding and charset errors LLMs make when decoding base64 by hand.

## Output

Returns the decoded UTF-8 plain text string corresponding to the provided base64 input. Returns a 400 error if the input text field is missing, not a string, or contains invalid base64.
