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
Returns a JSON object with per-coin data (symbol, USD price, Kraken USD price, supply in USD, peg deviation in bps, dominance %, 1d and 7d supply change %, Base chain supply), plus aggregate 7-day flow (USD + %), total stablecoin supply, liquidity trend label, a peg verdict (e.g. ALL_PEGGED), any active alerts, data sources, and an updated_at timestamp.
Example use cases
Depeg alert before large USDC transfer
“Before I move $500k of USDC, check if USDC is still pegged — give me the peg deviation in bps and any active alerts.”
Weekly stablecoin flow report for DeFi strategy
“Pull the 7-day netflow and supply change for USDC and USDT so I can decide whether stablecoin liquidity is expanding or contracting this week.”
Dominance check for portfolio rebalancing
“What's the current dominance percentage and total supply for the top 5 stablecoins? I want to see if USDC or USDT has been gaining ground lately.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/api/v1/smart-money/netflow?utm_source=zero.xyzWhen to prefer
Use this endpoint when your agent needs stablecoin-specific intelligence — peg health, supply flows, and dominance — rather than generic token prices. Ideal for DeFi risk assessment, pre-trade liquidity checks, or stablecoin-focused portfolio monitoring. Prefer over generic market data APIs when peg deviation, netflow, and depeg alerts are the core signal. No API key setup needed; pay $0.001 USDC per call via x402 on Base.
Side effects
- Payment not included or insufficient — returns HTTP 402 requiring x402 USDC payment on Base
- Invalid symbols parameter (non-existent ticker) — may return empty coins array
- top parameter out of range (must be 1–30) — returns validation error
- Data source (DefiLlama or Kraken) temporarily unavailable — stale or partial data with degraded sources list
- Network timeout on Cloudflare Worker — HTTP 5xx response
