How this service works
Circulating market cap of the top stablecoins (USDT, USDC, DAI...), highest first, source DefiLlama. Optional parameter: ?limit=<n> (1-100, default 20).
Output
Returns a JSON object with a count, the source URL (stablecoins.llama.fi), a fetch timestamp, and an array of stablecoins each containing: name, symbol, peg type (e.g. peggedUSD), backing mechanism (e.g. fiat-backed, algorithmic), and circulating USD market cap — sorted descending by market cap.
Example use cases
DeFi dashboard stablecoin overview
“Pull the top 10 stablecoins by circulating market cap so I can display them on my DeFi dashboard — I need the name, symbol, and current USD circulation for each.”
USDT vs USDC dominance check
“Get me the current circulating market caps of the top 5 stablecoins so I can see how USDT and USDC compare to each other and the rest of the market.”
Stablecoin research for market report
“Fetch the top 50 stablecoins ranked by circulating market cap, including their peg type and backing mechanism — I'm writing a report on the stablecoin landscape.”
Technical details
Endpoint
GEThttps://x402-seller-0ay3.onrender.com/api/defi/stablecoinsWhen to prefer
Choose this endpoint when you need live stablecoin market cap rankings sourced from DefiLlama, especially if you want fiat-backed vs algorithmic breakdown and peg metadata alongside circulating supply. Prefer it over on-chain queries when you need aggregated multi-chain circulating supply in a single call, and over generic crypto price endpoints when stablecoin-specific metrics (peg, mechanism) are required.
Side effects
- Invalid limit parameter (outside 1-100 range) may return an error or be clamped
- DefiLlama upstream outage may return stale or unavailable data
- Render cold-start latency if the service has been idle
- Payment failure via x402 protocol returns 402 status before data is served
