How this service works
Stablecoin market: total circulating market cap (USD) and the largest stablecoins by mcap with their peg type, peg mechanism (e.g. fiat-backed, crypto-backed) and dominance.
Output
Returns the total circulating stablecoin market cap in USD, plus a ranked list of stablecoins (up to the requested limit, default 10) each with: name, peg type (e.g. fiat, crypto, algorithmic), peg mechanism (e.g. fiat-backed, crypto-backed), market cap in USD, and dominance as a percentage of total stablecoin market cap.
Example use cases
Stablecoin dominance research
“What's the total stablecoin market cap right now, and which are the top 10 stablecoins? I want to see their peg types and how dominant each one is.”
Fiat vs crypto-backed breakdown
“Show me the top 25 stablecoins by market cap so I can see the split between fiat-backed, crypto-backed, and algorithmic stablecoins.”
DeFi risk assessment
“Pull the current stablecoin market overview for me — total market cap and the top 20 coins with their peg mechanisms — I want to understand concentration risk in the stablecoin sector.”
