# Bitwise Integer Analyzer

> Bitwise Integer Analyzer 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).

Analyzes a non-negative integer's bit structure, returning bit length, population count, trailing-zero count, power-of-two test, and hex/binary representations with optional zero-padding.

## Facts

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-integer-analyzer-85075ac8 -d '<json body>'
```

Example prompt: What's the bit length, population count, trailing-zero count, and binary representation of 2048, zero-padded to a width of 16 bits?

## When to prefer this

Use this endpoint when you need a comprehensive one-shot inspection of an integer's binary properties — bit length, population count, trailing zeros, power-of-two status, and both hex and binary representations — rather than calling separate endpoints. Prefer it over general-purpose code execution when you just need these specific metrics quickly and cheaply, especially when width-padded binary output is needed for display or protocol work.

## Known failure modes

- Value is not a valid non-negative decimal integer string — returns validation error
- Specified width is less than 1 or greater than 1024 — returns schema validation error
- Value requires more bits than the specified width — may return bounds error
- Non-numeric or negative string passed as value — rejected by regex pattern
- Missing required 'value' field — returns 400-level error

## How this service works

Inspect a non-negative integer's bit structure: bit length, set-bit count (population count), trailing-zero count, power-of-two test, and hex/binary representations. An optional width zero-pads the binary form.

## Output

Returns a structured object containing: bit_length (number of bits needed to represent the value), popcount (number of set bits), trailing_zeros (count of least-significant zero bits), is_power_of_two (boolean), hex (hexadecimal string), and binary (binary string, optionally zero-padded to the requested width).
