Scores run 0 to 100. Bands: EXTREME FEAR (below 25), FEAR, NEUTRAL (45 to 55), GREED, EXTREME GREED (above 75). Responses are cached for 5 minutes and the reading updates about every 30 minutes, so polling more often than every few minutes gains nothing. Browser requests from any origin are allowed.

Terms

• Free for commercial and non-commercial use.
• Show a visible link to https://sentiscale.app next to the number, for example "Fear & greed data by Sentiscale".
• Do not present the reading as investment advice. It is a sentiment gauge, and Sentiscale's track record shows no proven predictive edge.
• Fair use: heavy automated traffic may be rate-limited. The API may change; the v1 path will not change shape without notice on this page.
