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 with an array of stablecoin records (symbol, price_usd, kraken_usd, peg_dev_bps, status OK/DRIFT/WARN/DEPEG, supply_usd, supply_1d_pct, supply_7d_pct, dominance_pct, base_supply_usd), plus total supply flow over 1d/7d/30d, a liquidity_trend label (growing/flat/shrinking), an overall verdict (ALL_PEGGED, WATCH, or DEPEG_ALERT), an alerts array for any anomalies, data sources, and an updated_at timestamp.
Example use cases
Pre-trade stablecoin safety check
“I'm about to execute a large USDC swap on Base — first check if USDC is holding its peg and tell me the peg deviation in basis points, the Kraken cross-check price, and whether there are any active depeg alerts.”
Systemic risk-off signal in trading loop
“Run a stablecoin risk check across USDC, USDT, and DAI — are they all pegged, what's the 7-day supply flow trend, and is the liquidity verdict risk-on or risk-off right now?”
Monitoring USDT depeg on Kraken
“Is USDT showing any peg deviation or DRIFT status right now? I want the Kraken cross-check price, the peg dev in bps, and whether the overall verdict is ALL_PEGGED or DEPEG_ALERT.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/stablecoin-peg?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single consolidated stablecoin health check that combines on-chain supply data (DefiLlama) with a CEX price cross-check (Kraken) and returns a machine-readable verdict and alerts — ideal for trading agents doing pre-settlement risk checks or systemic risk-off detection in a loop. Prefer over querying DefiLlama and Kraken separately when you want peg deviation in basis points, Base chain supply, and a unified ALL_PEGGED/WATCH/DEPEG_ALERT verdict in one $0.001 call.
Side effects
- Upstream DefiLlama API unavailable — stale or missing supply data
- Kraken API timeout — kraken_usd field may be null for USDT/USDC/DAI
- Invalid symbol in comma-separated list — unknown symbols silently dropped or error returned
- top parameter out of range (must be 1–30) — validation error
- Rate limit or x402 payment failure — 402 Payment Required response
