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 per-coin entries (symbol, price_usd, peg_dev_bps, status OK/DRIFT/WARN/DEPEG, Kraken cross-check price, supply_usd, 1d/7d supply change %, dominance_pct, base_supply_usd), plus aggregate fields: total stablecoin supply, flow data over 1d/7d/30d, liquidity_trend (growing/flat/shrinking), a verdict (ALL_PEGGED/WATCH/DEPEG_ALERT), active alerts array, data sources, and updated_at timestamp.
Example use cases
Pre-settlement stablecoin safety check
“I'm about to convert $50k into USDC and USDT to park overnight — can you check if both are holding their peg right now, and flag anything that looks like a depeg or drift?”
Trading loop systemic risk-off signal
“Run a stablecoin liquidity check for me — is total stablecoin supply growing or shrinking over the last 7 days, and what's the overall verdict: all pegged, watch, or depeg alert?”
DAI depeg alert monitoring
“Check the current peg status for DAI specifically — what's its price, deviation in basis points, and has its supply changed significantly in the last day?”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/defillama/stablecoins?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs a fast, pre-validated stablecoin health signal before settling funds, executing a DeFi trade, or running a systemic risk check in a trading loop. It combines DefiLlama supply data with Kraken exchange cross-validation in a single call, returning a machine-readable verdict (ALL_PEGGED/WATCH/DEPEG_ALERT) and basis-point peg deviation — far more actionable than polling raw price feeds separately. Prefer it over generic crypto price endpoints when the specific question is peg integrity and liquidity direction, not spot trading price.
Side effects
- DefiLlama API unavailable — stale or missing supply data
- Kraken API unavailable — cross-check prices absent, status may degrade
- Invalid symbols parameter — returns empty coins array or 400 error
- top N out of range (must be 1-30) — validation error
- Network timeout from Cloudflare Worker — 503 or empty response
