# Bitwise OR (Arbitrary-Precision BigInt)

> Bitwise OR (Arbitrary-Precision BigInt) 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 OR across two or more arbitrarily large non-negative integers supplied as decimal strings, returning the result in decimal, hexadecimal, and binary.

## Facts

- Endpoint: POST https://bitwise.openverbs.com/v1/or
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/bitwise-or-arbitrary-precision-bigint-2c1a4b4d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_k0hpGduTb5wDMlhGC8EWj

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-or-arbitrary-precision-bigint-2c1a4b4d -d '<json body>'
```

Example prompt: Can you bitwise OR these three numbers for me — 255, 4096, and 16711680 — and show me the result in decimal, hex, and binary?

## When to prefer this

Choose this endpoint when you need bitwise OR on arbitrarily large integers (beyond 64-bit) that standard language runtimes cannot handle natively, or when you need multi-format output (decimal, hex, binary) in a single call. Prefer it over in-process solutions when operating in environments without BigInt support, or when auditing/logging of bitwise operations via an external service is required.

## Known failure modes

- Fewer than 2 values provided — validation error
- Non-numeric or negative value string passed — pattern mismatch error
- More than 256 values in the array — maxItems exceeded error
- Malformed JSON body — parse error
- Insufficient payment balance — x402 payment required response

## How this service works

Bitwise OR 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 bitwise OR result expressed in three formats: decimal string, hexadecimal string, and binary string. The computation supports arbitrarily large integers via BigInt evaluation.
