# pp-coingecko

This skill tells your agent how to pull crypto data from the public CoinGecko API through the coingecko-pp-cli binary. Prices, coin lists, global market stats — no key for basic endpoints.

## What it does

The skill does not fetch anything itself. It documents the CLI for the agent: which commands exist, what they return, how to parse the response. Commands are grouped under `coins`, `global`, `ping`, `search`, and `simple`. A `which` subcommand maps a plain-language capability to the right command, and `--agent` expands to `--json --compact --no-input --no-color --yes` for clean piping.

You need the binary before any of this works. Install it with `npx -y @mvanhorn/printing-press-library install coingecko --cli-only`, then confirm with `coingecko-pp-cli --version`. If `npx` is unavailable, there is a Go fallback that needs Go 1.26.6 or newer. No authentication is involved, and `coingecko-pp-cli doctor` checks the setup.

The CLI is read-only. Requests that create, update, delete, publish, or otherwise change remote state are out of scope — if that is what you need, this skill will not help. Responses arrive wrapped in `meta` and `results`, and `meta.source` tells you whether the data came live or from the local SQLite store.

# Coingecko — Printing Press CLI

## Prerequisites: Install the CLI

This skill drives the `coingecko-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 `$HOME/.local/bin` on macOS/Linux and `%LOCALAPPDATA%\Programs\PrintingPress\bin` on Windows:
   ```bash
   npx -y @mvanhorn/printing-press-library install coingecko --cli-only
   ```
2. Verify: `coingecko-pp-cli --version`
3. Ensure the reported install directory is on `$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):

```bash
go install github.com/mvanhorn/printing-press-library/library/payments/coingecko/cmd/coingecko-pp-cli@latest
```

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 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. This printed CLI exposes read-only commands for inspection, export, sync, and analysis.

## HTTP Transport

This CLI uses Chrome-compatible HTTP transport for browser-facing endpoints. It does not require a resident browser process for normal API calls.

## Command Reference

**coins** — Manage coins

- `coingecko-pp-cli coins detail` — Get current data for a coin
- `coingecko-pp-cli coins list` — List all coins with id, symbol, and name
