How this service works
Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.
Output
A JSON object containing per-coin data (symbol, price_usd, peg deviation in bps, total supply, 7d supply flow %, Base chain supply, dominance %), plus aggregate fields: total stablecoin supply, 7d flow in USD and %, liquidity trend label, an overall verdict (e.g. ALL_PEGGED), any active alerts, data sources, and a timestamp.
Example use cases
Stablecoin depeg risk alert
“Are any of the top 5 stablecoins showing significant peg deviation right now? Flag anything more than 20 bps off.”
DeFi liquidity trend check
“Has overall stablecoin supply been growing or shrinking over the past 7 days, and what's the total market size?”
USDC vs USDT supply comparison
“Pull the latest supply, peg deviation, and 7-day flow for USDC and USDT so I can compare them.”

Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/api/stablecoin-flows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, no-API-key, pay-per-call snapshot of stablecoin peg health and supply flows — especially inside an onchain AI agent that already handles x402/USDC micropayments. It's ideal for depeg monitoring, DeFi risk assessment, or liquidity trend analysis. Prefer alternatives if you need tick-by-tick price feeds, order book depth, or non-stablecoin assets.
Side effects
- Upstream DefiLlama or Kraken API unavailable — stale or missing data returned
- Invalid symbol in 'symbols' param — coin may be silently omitted from results
- 'top' param out of range (>30 or <1) — rejected with validation error
- x402 payment failure — 402 response returned before data is served
- No stablecoin data freshness guarantee — 'updated_at' may be several minutes old during congestion
