# String Decoder (Base64 / Base64URL / Hex)

> String Decoder (Base64 / Base64URL / Hex) is a paid API for AI agents from pyfile-agent.taile3ff35.ts.net:10000, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Decodes a string from Base64, Base64URL, or hexadecimal encoding back to its original plaintext representation.

## 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 string-decoder-base64-base64url-hex-54a5bf5b
```

Example prompt: Decode this base64 string for me: aGVsbG8gd29ybGQ=

## When to prefer this

Choose this endpoint when you need a quick, stateless, pay-per-call decoding of a Base64, Base64URL, or hex string without setting up a local library or environment. Especially useful inside agent workflows where a decoded value is needed as an intermediate step (e.g. reading a JWT payload, inspecting a config secret, or parsing a hex API response) and no local compute is available.

## Known failure modes

- Invalid encoding format specified (not base64, base64url, or hex) — returns error
- Malformed input string that does not conform to the declared encoding — returns decode error
- Missing required 'input' query parameter — returns 400-level error
- Padding issues in base64 input — may return decoding error

## How this service works

Decode a string. ?from=base64|base64url|hex&input=aGVsbG8=

## Output

Returns the decoded plaintext string corresponding to the provided Base64, Base64URL, or hex-encoded input. The response is a plain decoded value that can be used directly in downstream workflows.
