## When to prefer this

Choose this endpoint when you need on-chain USYC oracle price data, yield rates derived from actual price movement, full historical price records on Arc, or supply figures — particularly for DeFi agents monitoring tokenized Treasury yield or building allocation strategies around Circle's USYC.

## Known failure modes

- Payment not included or invalid — 402 payment required error
- API unavailable or upstream oracle data missing — 503 or timeout
- Malformed request — 400 bad request if query params are invalid
- USYC oracle data temporarily stale or not updated — may return cached or outdated price

## How this service works

The price of USYC (Circle's tokenized money market fund of short-term US Treasuries) from the oracle its Teller mints and redeems at, the yield its price shows over 7 and 30 days as a yearly rate, every published price on Arc, and the supply on Arc.

## Output

Returns the current USYC oracle price (as used by Teller for minting and redemption), annualized yield derived from price appreciation over 7 and 30 day windows, a complete list of every price published on Arc, and the current total USYC supply on Arc.
