How this service works
Stablecoin intelligence — circulating supply, $1.00 peg deviation and per-chain breakdown (incl. Base) for USDC and other stablecoins (DefiLlama). Pay-per-call via x402.
Output
A JSON object containing: stablecoin name and asset symbol, current price, absolute peg deviation percentage from $1.00, a peg status label (e.g. 'on-peg'), peg mechanism (e.g. 'fiat-backed'), total circulating supply in USD, and a breakdown for the Base chain showing circulating USD and its percentage share of total supply. Returns HTTP 4xx (without charging) when upstream data is unavailable.
Example use cases
DeFi protocol peg health check
“I'm about to deploy a large USDC position in a DeFi protocol — first check if USDC is currently on-peg and what the deviation from $1.00 is, so I know there's no depeg risk right now.”
Base chain liquidity assessment
“How much USDC is actually circulating on Base right now, and what share does that represent of USDC's total supply across all chains?”
Stablecoin market monitoring dashboard
“Pull the latest peg status, price, and total circulating supply for USDC so I can update my stablecoin health dashboard.”
Technical details
Endpoint
POSThttps://fiatdock.com/v1/stablecoin/intelWhen to prefer
Choose this endpoint when you need real-time stablecoin peg health, circulating supply, or Base-chain-specific supply data for USDC or other major stablecoins. Prefer it over generic crypto price APIs when you specifically need peg deviation, per-chain supply breakdown, or DeFi-native stablecoin intelligence. The pay-per-call x402 model makes it cost-effective for sporadic lookups without a subscription.
Side effects
- Upstream DefiLlama data unavailable — returns >=400 status and no charge is applied
- Unknown or unsupported stablecoin asset symbol — likely returns an error response
- Network timeout reaching DefiLlama data source
- Stale data if DefiLlama feed is delayed
