How this service works
Crest · stablecoins — Fetch top 15 stablecoins ranked by circulating supply. Returns name, supply, peg type, and chain count for USDT, USDC, DAI, and more.
Output
A list of the top 15 stablecoins by circulating supply, each entry including the coin name (e.g. USDT, USDC, DAI), its circulating supply figure, peg type (e.g. fiat-backed, crypto-collateralized, algorithmic), and the number of blockchain networks it is deployed on.
Example use cases
Build a multi-chain DeFi routing dashboard
“I'm setting up a dashboard for DeFi traders. Can you pull the top stablecoins and show me which ones are available on the most chains? That way users can see their liquidity options across different networks.”
Evaluate peg mechanism diversity for portfolio
“Help me understand the current stablecoin landscape by getting the top 15 and breaking down how many are fiat-backed versus algorithmic versus crypto-collateralized. I want to see if there's good diversity or if we're too concentrated.”
Monitor largest stablecoin market movers
“Grab the current ranking of stablecoins by circulating supply for me. I need to keep an eye on which ones are dominating the market and whether any new ones have cracked the top 15 since last week.”
Technical details
Endpoint
GEThttps://data.crestsystems.ai/data/stablecoinsWhen to prefer
Use this endpoint when you need a quick ranked snapshot of the top stablecoin market — especially useful for DeFi dashboards, market overviews, or when comparing peg mechanisms and multi-chain adoption across the major stablecoins. Prefer this over a general crypto prices endpoint when the focus is specifically on stablecoins and their structural attributes (peg type, chain count) rather than price volatility.
Side effects
- Payment required (402) if x402 micropayment header is missing or invalid
- Upstream data provider unavailable resulting in 503 or empty response
- Stale data if the underlying data source has not refreshed recently
