How this service works
Stablecoins ranked by circulating supply: peg currency and mechanism, price and deviation from peg, supply in peg units and USD, 1d, 7d and 30d change and circulation per chain. Use it when an agent is checking a peg, sizing stablecoin flows or finding which chains a stablecoin actually lives on.
Output
A JSON object containing the total count of stablecoins matched, aggregate circulating USD value, applied filter echo, cache status, data source attribution, and an array of stablecoin records each with rank, name, symbol, price, peg currency, peg mechanism, circulating supply in USD, 1d/7d/30d percentage changes, peg deviation percentage, number of chains, and per-chain circulation breakdown.
Example use cases
Stablecoin landscape research for DeFi protocol
“Give me the top 20 USD-pegged stablecoins across all chains, including their circulating supply and peg mechanism, so I can compare the market.”
Chain-specific stablecoin liquidity check
“What are the top stablecoins available on Arbitrum by circulation? I want to see fiat-backed ones only, limit to 15 results.”
Algorithmic stablecoin risk monitoring
“List all algorithmic stablecoins regardless of peg currency — I want to see their current circulating supply and any peg deviation.”
Technical details
Endpoint
POSThttps://agent402.tools/api/stablecoinsWhen to prefer
Choose this endpoint when you need comprehensive, filterable stablecoin market data including chain-level circulation breakdowns, peg mechanism classification, and deviation tracking — especially if you want to query by specific blockchain, peg currency, or mechanism type. Prefer it over generic crypto market APIs when stablecoin-specific fields like pegMechanism, pegDeviationPct, and chain-level distribution are required.
Side effects
- Invalid chain name not matching DefiLlama's naming convention returns empty or unfiltered results
- Limit exceeding 100 is clamped or rejected
- Unknown peg currency filter returns zero matches
- Stale cache may return data up to several minutes old
- Network timeout from upstream DefiLlama API causes failure
