# Bitwise Shift (Left/Right)

> Bitwise Shift (Left/Right) is a paid API for AI agents from bitwise.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Shifts a non-negative integer left or right by a given number of bits, returning decimal, hex, and binary representations.

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 bitwise-shift-left-right-a958e328 -d '<json body>'
```

Example prompt: Shift the integer 255 left by 4 bits and give me the result in decimal, hex, and binary — no width mask needed.

## When to prefer this

Use this endpoint when you need to perform a logical left or right bit shift on an arbitrary-precision non-negative integer and want the result expressed in decimal, hex, and binary simultaneously. Prefer it over general-purpose code execution when you want a lightweight, purpose-built arithmetic operation without spinning up a compute environment. The optional width masking makes it ideal for simulating fixed-width registers (e.g., 8/16/32/64-bit).

## Known failure modes

- Negative integer input — value must be a non-negative decimal string
- Shift amount exceeds 1024 — maximum shift amount is 1024 bits
- Bit width exceeds 1024 — maximum width is 1024 bits
- Left shift input does not fit within the specified width — validation error
- Non-numeric or non-integer string for value — pattern mismatch
- Missing required fields (value, amount, direction) — schema validation error

## How this service works

Shift a non-negative integer left or right by `amount` bits. A right shift is logical (fills with zeros). A left shift grows freely unless a `width` is given, in which case the result is masked to that width and the input must fit it. Returns decimal, hex and binary.

## Output

Returns the shifted integer value in three representations: decimal (base 10), hexadecimal (base 16), and binary (base 2). For masked left shifts, the result is already truncated to the specified bit width.
