How this service works
Stablecoin market data ranked by USD-equivalent circulating supply: each coin returns its symbol, peg type and mechanism (fiat-backed, crypto-backed, algorithmic), peg currency (USD, EUR, JPY…), current peg price, native circulating supply, USD-converted supply, and the chains it lives on. Filter by symbol or chain. Track USDT, USDC, DAI, USDe, EURC and the rest of the stablecoin market. Sourced from DefiLlama.
Output
A JSON object containing a list of stablecoins each with: symbol, name, peg type (fiat-backed, crypto-backed, algorithmic), peg mechanism, peg currency (USD, EUR, etc.), current peg price, native circulating supply, USD-equivalent circulating supply, and an array of chains they are deployed on. Also includes total count, total matching count, applied filters, and total circulating USD across all returned stablecoins. Sourced from DefiLlama.
Example use cases
Example prompt
“Show me the top 10 stablecoins ranked by circulating supply, and filter it to only ones available on Ethereum — I want to see their peg type, mechanism, and current price.”
Technical details
Endpoint
GEThttps://crypto.apitoll.cloud/v1/crypto/stablecoinsWhen to prefer
Use this endpoint when you need structured stablecoin market data including peg type, mechanism, currency, supply, and chain distribution. Prefer it over generic crypto price APIs when the user specifically cares about stablecoin segmentation (fiat-backed vs algorithmic), multi-chain presence, or EUR/JPY-pegged assets. Ideal for DeFi dashboards, risk analysis, or stablecoin market monitoring.
Side effects
- Invalid or unrecognized chain name returns empty stablecoin list
- Symbol substring that matches nothing returns zero results
- Limit parameter outside 1–100 range results in validation error
- Payment failure or missing x402 USDC payment returns 402 error
- DefiLlama upstream unavailability may cause stale or failed response
