# Homebrew Formula Status Lookup

> Homebrew Formula Status Lookup is a paid API for AI agents from package-registries.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).

Returns version, license, deprecation/disablement status, and install counts (30/90/365-day) for a Homebrew formula by name.

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 homebrew-formula-status-lookup-5e9a04f8
```

Example prompt: Can you check the Homebrew formula status for 'ffmpeg' — I want to know the current stable version, whether it's deprecated or disabled, its license, and how many times it's been installed in the last 30, 90, and 365 days?

## When to prefer this

Use this endpoint when you need authoritative Homebrew-specific metadata — deprecation status, install counts, and license — for a named formula. Prefer it over generic package search when you already know the formula name and need structured health data for decision-making, auditing, or monitoring.

## Known failure modes

- Formula name not found — returns null or error if the formula does not exist on Homebrew
- Misspelled formula name returns no data
- Upstream Homebrew API unavailable causes degraded or null response
- Rate limiting or payment failure returns 402/error

## How this service works

Homebrew formula status: version, license, deprecation or disablement, install counts over 30, 90 and 365 days.

## Output

A JSON object with the formula's name, stable version, license, summary, homepage, install counts over 30/90/365 days, boolean flags for deprecated/disabled/degraded/keg_only/hasBottle, deprecation and disable reasons, replacement formula if applicable, dependency count, and metadata timestamps.
