Description

Measures the current market appetite for altcoins by blending liquidity flow, Bitcoin dominance trends, and capital rotation signals. It quantifies how willing investors are to move risk from Bitcoin and stablecoins into the broader altcoin market — a key early cue of altseason momentum.

What this endpoint provides

A simplified but powerful gauge of capital rotation pressure between major crypto segments. It helps automations and AI agents assess if risk appetite is contracting toward Bitcoin/stablecoins or expanding toward altcoins — serving as a complementary sentiment layer to BTC Dominance, Altcoin Rotation Radar, and Rotation Momentum Index.

Response fields

appetite_score

Normalized score (0–1) representing the current strength of market appetite for altcoins. Higher = stronger rotation into alts.

state

Simplified categorical label (bearish, neutral, bullish) indicating overall altcoin appetite.

message

Human-readable summary describing the current state in plain language.

context.stablecoin_share

Percentage of total crypto market cap held in stablecoins — higher values indicate defensive positioning.

context.btc_eth_share

Combined market share of BTC and ETH — a proxy for "major dominance" over the total market.

context.market_cap_change_24h

Overall 24h change in global crypto market cap, used to detect whether flows occur in expanding or contracting liquidity.

timestamp

UTC time when the indicator was last updated.

Interpretation & Use

The Altcoin Appetite Index serves as an actionable signal of risk rotation potential within the crypto market:

• **Low (<0.3)** → Risk-off environment; capital consolidating into BTC and stablecoins.

• **Neutral (0.3–0.6)** → Wait-and-see phase; investors tracking BTC stability before rotating into alts.

• **High (>0.6)** → Risk-on environment; strong appetite for altcoins and early altseason pressure.

When combined with the BTC Dominance, Altcoin Rotation Radar, and Rotation Momentum Index, this metric provides a comprehensive read on the rotational temperature of the market — helping identify when altcoins may start outperforming.
