How this service works
Total stablecoin market capitalisation and the largest stablecoins by circulating supply across all chains (DefiLlama), with peg type/mechanism and live price — plus a depeg watch flagging any USD-pegged coin 2%+ off a dollar. The stablecoin-market commodity agents track; for a single Base-stablecoin peg check use stablecoin-peg. Not financial advice.
Output
Returns the aggregate stablecoin market capitalization, a ranked list of top stablecoins (up to 30) with each coin's name, circulating supply, peg type and mechanism, and live price — plus a depeg watch section highlighting any USD-pegged coin currently trading 2% or more away from $1.00.
Example use cases
Stablecoin depeg risk morning briefing
“Pull up the current stablecoin market overview and let me know if any of the top 15 USD-pegged stablecoins are trading more than 2% off their peg — I want a depeg alert summary for my morning report.”
DeFi dashboard market cap widget
“What's the total stablecoin market cap across all chains right now, and who are the top 10 by circulating supply? Include their peg type and current price.”
Algorithmic vs collateralized stablecoin research
“Show me the top 25 stablecoins ranked by circulating supply with their peg mechanisms so I can compare algorithmic versus collateralized ones and see if any are currently depegged.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/stablecoin-mcap?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a broad market-level view of the stablecoin ecosystem — total market cap, cross-chain supply rankings, peg types, and a depeg watch across many coins. Prefer this over stablecoin-peg (which checks a single Base-chain stablecoin) when you need multi-coin, multi-chain stablecoin market intelligence or want to catch systemic depeg events.
Side effects

- Payment failure via x402 protocol returns 402 Payment Required
- Rate limiting or network timeouts may return 5xx errors
