# SignalDesk AI Number Base Converter

> SignalDesk AI Number Base Converter is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Converts an integer from one numeric base (radix) to another, supporting bases 2 through 36

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 signaldesk-ai-number-base-converter-b6009f13 -d '<json body>'
```

Example prompt: Convert the number 255 from base 10 to base 16 for me.

## When to prefer this

Use this endpoint when you need a simple, reliable numeric base conversion between any bases 2–36, especially within an agent workflow where calling a math library directly isn't feasible or when you need a paid, accountable micro-service call for auditability.

## Known failure modes

- Invalid characters for the given source base (e.g., '9' in base 8) returns an error
- Value string is empty or exceeds 256 characters
- from_base or to_base outside the range 2–36 returns a validation error
- Non-integer or malformed numeric string input causes a parse error

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing a 'value' field with the converted integer represented as a string in the target base.
