# Tanod utilpeek Text Encode/Decode

> Tanod utilpeek Text Encode/Decode is a paid API for AI agents from tanod.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Encodes or decodes text using codecs including base64, base64url, base32, hex, URL, HTML, quoted-printable, ROT13, punycode, IDNA, and JWT (decode-only, unverified).

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 tanod-utilpeek-text-encode-decode-4c66275f -d '<json body>'
```

Example prompt: Can you base64-decode this string for me: 'SGVsbG8sIFdvcmxkIQ=='?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call text encoding or decoding utility without standing up your own library — especially useful in agent pipelines that need to inspect JWTs, sanitize URL parameters, or handle multi-format data interchange. Prefer it for one-off conversions across a wide variety of codecs (base64, hex, URL, HTML, ROT13, punycode, IDNA, quoted-printable) without needing a full SDK.

## Known failure modes

- Invalid codec name returns a 400 error
- Attempting to encode a JWT (direction=encode with codec=jwt) is not supported
- Text exceeding 100,000 characters is rejected
- Malformed base64/hex/JWT input that cannot be decoded returns an error
- Punycode/IDNA decode of invalid input returns an error

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns the encoded or decoded text as a string. For JWT decode, returns the header and payload claims as parsed JSON (signature is never verified). The original input is never logged or echoed back for JWTs.
