# Bitwise AND — Arbitrary-Precision Integer Operation

> Bitwise AND — Arbitrary-Precision Integer Operation is a paid API for AI agents from bitwise.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).

Computes the bitwise AND of two or more non-negative integers (as decimal strings) with arbitrary precision, returning the result in decimal, hexadecimal, and binary formats.

## 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-and-arbitrary-precision-integer-operation-ea739260 -d '<json body>'
```

Example prompt: Compute the bitwise AND of these three numbers: 255, 170, and 204 — give me the result in decimal, hex, and binary.

## When to prefer this

Choose this endpoint when you need arbitrary-precision bitwise AND across two or more very large integers that exceed native 64-bit integer limits, or when you need the result in multiple formats (decimal, hex, binary) simultaneously. It is purpose-built for AND specifically, unlike generic big-number libraries. Prefer it when precision and multi-format output matter over implementing the operation locally.

## Known failure modes

- Fewer than 2 values provided — validation error
- More than 256 values provided — validation error
- Non-numeric or negative strings in values array — pattern validation failure
- Malformed JSON body — 400 bad request
- Payment not included or insufficient — 402 Payment Required

## How this service works

Bitwise AND across two or more non-negative integers (given as decimal strings, evaluated as arbitrary-precision BigInt). Returns the result in decimal, hex and binary.

## Output

Returns an object containing the AND result expressed in three formats: decimal (string), hexadecimal (string), and binary (string). Accepts between 2 and 256 arbitrary-precision non-negative integers as decimal string inputs.
