How this service works
50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.
Output
A JSON array of stablecoin objects each containing: symbol (e.g. USDT), current price in USD, circulating supply in USD, and peg deviation in basis points (negative = below peg, positive = above peg).
Example use cases
Detect stablecoin depeg alert
“Check all major stablecoins right now and tell me if any of them have deviated from their $1 peg by more than 20 basis points.”
DeFi portfolio risk assessment
“I'm about to deploy liquidity into a stablecoin pool — can you pull the latest peg deviation and circulating supply data for the top 15 stablecoins so I can pick the safest one?”
Stablecoin market overview report
“Give me a snapshot of the current stablecoin market: prices, circulating supply in USD, and how far each one is from its peg — grab up to 20 of them.”
Technical details
Endpoint
GEThttps://skinwinking.com/api/v1/data/stablecoins?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time stablecoin price and peg health data across multiple stablecoins in a single call. Prefer it over general crypto price APIs when peg deviation (in basis points) is specifically needed. It is pay-per-call at $0.002 USDC via x402, making it cost-effective for infrequent or agent-driven lookups without a subscription commitment.

- Payment not settled via x402 results in 402 Payment Required response
