Appstoreprice Hub

What it does

When your agent uses it

• Mentions App Store prices
• Which region is cheapest
• Turkey region price
• App price comparison

Example prompts

• “App Store prices,”
• “which region is cheapest,”
• “Turkey region price,”
• “/appstoreprice-hub”

Requirements

• Node.js

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

1. 1REST API (search/list): requires the FNV-1a signature headers X-Timestamp + X-Signature
2. 2RSC page stream (price details): directly parse fetch(url, { headers: { RSC: '1' } })

What it can do on your machine

Read from SKILL.md and the folder at commit ae8c5db. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 1 file in scripts/ (JavaScript), which the agent can run.

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • appstoreprice.org

  Also links to:

  • x.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Appstoreprice Hub loads about 1.8k tokens when it runs. Until then it costs about 206 tokens; SKILL.md has 516 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~206

When it runs · the whole SKILL.md, loaded when a task matches

~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description

A skill for querying App Store app prices across regions worldwide, using data from appstoreprice.org. It uses the Minis built-in browser (minis-browser-use CLI) to call the website's native signing function directly in the page context, with no API key and no need to implement the signing algorithm yourself. It supports searching for apps by name, querying prices for one app across all regions, retrieving rankings of the cheapest regions, and browsing app lists with pagination. This skill must be triggered when the user mentions "App Store prices," "which region is cheapest," "Turkey region price," "appstoreprice," "app price comparison," "low-price App Store regions," "which subscription region is the best value," or any scenario that requires cross-region price comparisons for iOS/macOS apps.

  && minis-browser-use execute_js --script "$(cat /var/minis/skills/appstoreprice-hub/scripts/api.js /tmp/asp_logic.js)"

const asp = AppStorePriceAPI();
const sr = await asp.search('Claude');
const app = sr.apps.find(a => a.developer?.includes('Anthropic'));
const tierNames = ['Claude Pro (monthly)', 'Claude Max 5x (monthly)', 'Claude Max 20x (monthly)', 'Claude Pro (annual)'];
const allTiers = await asp.prices_all(app.appStoreId);
return allTiers.map((prices, i) => {
  const sorted = [...prices].sort((a, b) => a.priceUsd - b.priceUsd);
  const usPrice = prices.find(p => p.region === 'US')?.priceUsd;
  return {
    tier: tierNames[i] || `Tier ${i+1}`,
    usPriceUsd: usPrice,
    cheapestTop5: sorted.slice(0, 5).map(p => ({
      ...p, saveVsUS: usPrice ? Math.round((1 - p.priceUsd / usPrice) * 100) + '%' : 'N/A'
    }))
  };
});
