How this service works
Public-data market intel for AI agents: token prices (CoinGecko), DefiLlama TVL/fees/stables, Polymarket odds. Otto-compatible path names. $0.001 USDC per call on Base. No LLM/TTS/image.
Output
Returns a JSON object with a 'data' field containing: a list of the top 30 USD stablecoins with their symbol, current price, and peg deviation in basis points; plus a 'depeg_alerts' array flagging any coins significantly off their peg. Also includes meta information noting the DefiLlama source, endpoint path, and cost of $0.001 USDC per call.
Example use cases
Depeg alert monitoring for DeFi portfolio
“Check the stablecoin watch right now and tell me if any major stablecoins have triggered a depeg alert — I need to know if USDT or USDC is losing its dollar peg.”
Real-time peg deviation dashboard
“Get me the current peg deviation in basis points for all the top 30 USD stablecoins so I can see which ones are drifting the most from $1.”
Automated stablecoin risk scan for trading bot
“Run a stablecoin watch scan and return any coins with a peg deviation above 10 basis points — I'm building a risk check before executing a swap.”
Technical details
Endpoint
GEThttps://joe-market-data.marnick-yezo.workers.dev/stablecoin-watchWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call stablecoin health check using DefiLlama data, especially in agentic pipelines that want depeg alerts without setting up a full data subscription. Ideal for DeFi bots, risk monitors, or portfolio agents that need a quick peg status snapshot for the top 30 USD stablecoins at minimal cost ($0.001 USDC).
Side effects
- DefiLlama upstream outage causes empty or stale data response
- Rate limiting or payment failure on Base returns 402 error
- Malformed response if DefiLlama schema changes upstream
- Network timeout from Cloudflare Workers edge node
