How this service works
Stablecoin monitor for agents: supply, price and peg deviation for every tracked stablecoin, plus a de-peg alert list. Paid per call via x402 (USDC on Base).
Output
A JSON object containing an array of stablecoin records (each with symbol, circulating supply, price, and peg deviation) along with a de-peg alert list and the total circulating USD value across all tracked stablecoins.
Example use cases
DeFi risk dashboard peg check
“Pull the top 100 stablecoins and tell me which ones are currently showing a de-peg alert or have a price deviation of more than 0.5% from their peg.”
Total stablecoin market size snapshot
“What's the total USD value of all stablecoins in circulation right now, and what are the top 10 by supply?”
Automated de-peg alert for trading bot
“Check the stablecoin monitor for any coins in the top 20 that are currently flagged as de-pegged and give me their symbols, prices, and how far off their peg they are.”
Technical details
Endpoint
GEThttps://stablecoins.x402utils.workers.dev/v1/top?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time stablecoin supply, price, and peg deviation data in a single call, especially when you want a de-peg alert list included. Prefer this over general crypto market APIs when stablecoin-specific monitoring and peg health are the primary concern, and when you are operating in a pay-per-call agent context using x402 micropayments on Base.
Side effects
- Payment not provided or invalid x402 USDC payment on Base — returns 402 Payment Required
- Invalid 'top' parameter value (outside 1-100 range) — may return 400 Bad Request
- Upstream data source unavailable — may return 503 or stale data
- Rate limiting if payment is not properly processed
