pp-exchangerate-api
Every ExchangeRate-API endpoint, plus a local rate history, watchlists, drift alerts, and an MCP server no one else... Trigger phrases: `convert USD to EUR`, `what's the exchange rate for`, `check my FX quota`, `sync exchange rates`, `what was USD/EUR last week`, `use exchangerate-api`, `run exchangerate-api`.
Why this skill is useful
Adds executable commands for live FX rates, historical context, and monitoring that extend the AI's capabilities beyond standard API calls.
What it needs
Requires exchangerate-api-pp-cli installed locally. About 8k tokens when loaded. Last updated 2026-08-06. 1,890 stars on the source repository.

See the repository agent guide, section "Generated artifacts: registry.json, cli-skills/". --> ExchangeRate-API — Printing Press CLI Prerequisites: Install the CLI This skill drives the exchangerate-api-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: exchangerate-api-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer): If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. When to Use This CLI Reach for exchangerate-api-pp-cli whenever an agent or script needs live FX rates, multi-target conversions, or persistent historical context. It's the right pick over a one-off HTTP call when the agent will run more than once on the same data, when quota matters (1500/mo Free tier), or when the workflow benefits from a watchlist, drift report, or cross-rate matrix that requires local state. Use the MCP server (mcp serve) when wiring FX context into Claude Desktop, Cursor, or Windsurf. When Not to Use This CLI Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. …
How to use it
Reference it in AdaL, Claude Code, Cursor or any coding agent — nothing to install:
