How this service works
Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.
Output
Returns a JSON object with a timestamp, a list of stablecoins sorted by circulating supply (each with symbol, name, price, peg status, deviation in basis points, mechanism, chain count, and 24h/7d/30d price changes), a separate array of any currently depegged coins, and the total stablecoin circulating supply in USD.
Example use cases
Pre-trade stablecoin risk check
“Before I move funds, check whether USDC is currently on peg and tell me its 24-hour and 7-day price change.”
DeFi dashboard depeg alert
“Pull stablecoin health for the top 25 coins by circulating supply and list any that are currently depegged so I can update my risk dashboard.”
Stablecoin market overview
“Give me a summary of the overall stablecoin market — total circulating supply, which coins are on peg, and how each has moved over the last 30 days.”
Technical details
Endpoint
GEThttps://three.ws/api/x402/stablecoin-health?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time stablecoin peg status, deviation metrics, and circulating supply data in a single call — especially when filtering by a specific coin like USDC or needing ranked lists of the largest stablecoins. Prefer it over generic crypto price APIs when peg health (deviation basis points, on-peg/depegged status) and multi-chain coverage data are the primary concern.
Side effects
- Unknown or misspelled symbol returns empty coins array
- limit parameter out of range (1-100) returns validation error
- Payment not included or insufficient USDC causes 402 response
- Service unavailable if upstream price feeds are down
- Stale data if timestamp is significantly behind real-time
