# AgentTools Number Base Converter

> AgentTools Number Base Converter is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-12).

Converts integers from one numeric base to another (bases 2–36, e.g. binary, octal, decimal, hex) with BigInt precision and no magnitude limit.

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 agenttools-number-base-converter-48cf8004
```

Example prompt: Convert the binary number 11111111 to hexadecimal — that's from base 2 to base 16.

## When to prefer this

Use this endpoint when you need reliable, precision-safe base conversion for arbitrarily large integers across any base from 2 to 36. It is ideal when standard JavaScript Number precision (53-bit) would be insufficient, or when you need conversions beyond the common binary/octal/decimal/hex quartet — such as base-32 or base-36 encodings.

## Known failure modes

- Invalid digits for source base (e.g. '9' in a base-8 number) — returns an error
- Source or target base outside the 2–36 range — returns validation error
- Missing required query parameters (value, from, to) — returns 400-level error
- Non-integer or floating-point value input — likely unsupported

## How this service works

Convert integers between any bases from 2 to 36 — binary, octal, decimal, hexadecimal and beyond — with BigInt precision (no limit on magnitude). Use this when an agent needs to binary, octal, decimal, hex — any base 2–36.

## Output

Returns the converted number as a string representation in the target base, computed with BigInt precision so arbitrarily large integers are handled correctly without floating-point loss.
