API.SH vs the official Crypto Fear & Greed API

Alternative.me, which publishes the Crypto Fear & Greed Index, offers its own free public API for the index. API.SH returns the same index with the 7- and 30-day averages already computed, date-range filtering and the same key and JSON shape as the rest of API.SH, which helps if you already pull other market data through it.

Alternative.me's free endpoint is enough for a single script; Apify actors, RapidAPI listings and CoinMarketCap's index each need their own account and format. API.SH is worth it when you want the index next to other API.SH data, in Sheets, Zapier or n8n, or inside an AI agent through MCP.
