How this service works
Stablecoins tracked by DefiLlama: circulating supply, peg type and mechanism, price, and the chains each one runs on. With symbol, that coin; without it the 50 largest. Attribution: Data: DefiLlama. Information only, not financial advice.
Output
Returns a JSON object with a list of stablecoins, each including name, symbol, current price, peg type (e.g. peggedUSD), peg mechanism (e.g. fiat-backed), circulating supply in USD, and supported chains. Also includes count, data source attribution (DefiLlama), cache timestamp, and a disclaimer. Data is cached for 30 minutes.
Example use cases
Stablecoin due diligence before swap
“Before I swap into USDC, can you pull its current price, peg mechanism, and circulating supply so I know it's properly backed?”
Multi-chain stablecoin availability check
“I'm building on Manta network — which stablecoins are currently available there and what are their circulating supplies?”
Stablecoin market overview for portfolio report
“Give me a full list of all tracked stablecoins right now with their prices, peg types, and USD circulating supply so I can include it in my DeFi report.”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/defi/stablecoins?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need stablecoin-specific metadata — price, peg type, peg mechanism, chain availability, and circulating supply — especially when filtering by a specific symbol. Prefer this over generic crypto price endpoints when peg mechanism or chain distribution data is also needed. Backed by DefiLlama's stablecoin dataset with 30-minute caching for efficiency.
Side effects
- Invalid or unknown symbol returns empty stablecoins array
- DefiLlama upstream API unavailability may cause stale or missing data
- Rate limiting or payment failure returns 402 Payment Required
- Cached data may be up to 30 minutes old, not reflecting real-time price changes
