Returns Fear and Greed observations with the index value, classification, timestamp and available price context.
Response fields and how to read them
The table follows the official response contract, including nested fields and useful response metadata. [] denotes an array item. Required means required within its parent object, not that a conditional parent always exists. A nullable type permits null; an optional field can be absent. Use the documented conditions below to distinguish missing, empty and zero values. Units and reporting windows apply only where explicitly documented.

Coverage, units and freshness
The index is a 0–100 score, not a probability or return forecast. Historical sentiment does not establish a trading outcome.
Inspect any returned observation time, cache status, watermark, pagination and errors using their documented meanings. A successful request alone does not establish complete coverage. Where no freshness or completeness guarantee is documented, treat it as unknown. Saved Examples are historical and viewing them does not refresh data or execute a new call.

Ask your agent to Review the recorded crypto Fear and Greed index over time. Provide the required inputs above. If Toolmu is already connected, reuse that connection; otherwise use the setup instructions on this page. Before a paid execution, the agent must read the current Tool contract and check availability, the credit ceiling, balance, budget and your authorization. It should then execute the Tool and explain the returned fields and limitations.
