## When to prefer this

Use this endpoint when you need historical peg price data for stablecoins tracked by DefiLlama — particularly when analyzing peg stability, depeg events, or backtesting strategies that depend on stablecoin price accuracy. Prefer this over generic crypto price APIs when you specifically need stablecoin peg tracking data from DefiLlama's comprehensive coverage.

## Known failure modes

- Service unavailable or timeout if DefiLlama upstream is down
- Payment failure if USDC balance is insufficient for the $0.005 per-call fee
- Empty or partial response if DefiLlama has incomplete data for certain stablecoins
- Rate limiting if too many requests are made in a short period
