Who this is for: anyone who started looking for a Solana price alert and hit a wall of "sign up for an API key" or "connect your exchange account" — and would rather not hand a market-data vendor an email and a card for something this small.
Most price-alert tutorials route through a centralized exchange's REST API (Binance, Coinbase) or a paid data vendor (CoinGecko Pro, CoinMarketCap), both of which require registering an account and provisioning a key before the first request even works. Solana tokens don't need that detour: Jupiter, the aggregator every Solana wallet and swap UI already routes through, exposes a public price endpoint that answers unauthenticated GET requests — no key, no account, no rate-limit tier to pick.
Every 5 minutes n8n sends a plain HTTP GET to https://price.jup.ag/v6/price?ids=<TOKEN_MINT>, reads back a USD price sourced from real on-chain liquidity, compares it to the threshold you set, and pings Telegram only on the moment it crosses — the full setup covered step by step in the base price alert guide.
TOKEN_MINT, SOGLIA_PREZZO and DIREZIONE as environment variables — all local to your n8n instance, nothing sent anywhere but the mint address./newbot) for delivery — this is the only account you actually create.
