# CoCo Number Base Converter

> CoCo Number Base Converter is a paid API for AI agents from cocoeatsai.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).

Converts a number from a specified base into decimal, hexadecimal, octal, binary, and base36 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 coco-number-base-converter-4dd5cfee
```

Example prompt: Convert the number FF from base 16 to all its common representations — I want to see it in decimal, binary, octal, and base36.

## When to prefer this

Use this endpoint when an agent needs to convert a number between common numeral systems (binary, octal, decimal, hex, base36) in a single call and receive all representations at once. Prefer it over manual computation when multiple output bases are needed simultaneously, or when integrating number-base logic into an automated pipeline without implementing conversion logic locally.

## Known failure modes

- Invalid value for the given from_base (e.g. digit not valid in that base) — likely returns an error or unexpected result
- Missing required query parameters (value or from_base) — may return 400 or error JSON
- Non-numeric or malformed input string — conversion error
- Unsupported base value — may return error if base is out of supported range

## Output

A JSON object containing the input number converted into five standard representations: decimal (base 10), hexadecimal (e.g. '0xff'), octal (e.g. '0o377'), binary (e.g. '0b11111111'), and base36. All values are returned as strings.
