## About

## What it does
Crypto Sentiment Index returns the current crypto market sentiment as a numeric value, a classification label, and a Unix timestamp in milliseconds. Send an optional `limit` query parameter to control how many recent entries you want back, up to 30.

Use it when you need a lightweight signal for dashboards, trading bots, alerts, or market commentary. The response includes a `source` string and an `entries` array, so you can trace where the sentiment data came from and iterate over the latest readings without extra parsing.

Each entry contains `value` from 0 to 100, `classification`, and `timestamp`. That makes it easy to compare the current reading with historical snapshots, threshold alerts, or other market indicators in your own app.

If you need a compact sentiment feed for crypto products, Crypto Sentiment Index keeps the response focused on the fields that matter.
