How this service works
Quotes each stablecoin against real US dollars on Kraken and Coinbase and, separately, against USDT on Binance, OKX and Bybit. Only the dollar quotes enter median_price and deviation_bps, because a USDT quote measures two stablecoins against each other and not the dollar; those are reported apart and labelled. Deviation is always in basis points against 1.00, never in percent. agreement is the point of the whole endpoint: a deviation at a single venue is a venue problem, a deviation everywhere i
Output
Returns per-stablecoin data including median price computed from USD-quoted venues (Kraken, Coinbase), deviation from $1.00 in basis points, per-venue USD quotes, separately labelled USDT-quoted prices from Binance/OKX/Bybit, an agreement signal indicating whether deviations are venue-specific or systemic, and depth-at-peg metrics computed using the requested peg band.
Example use cases
Systemic depeg alert for DeFi protocol
“Run a peg check on USDC and DAI across all five venues — Binance, Coinbase, Kraken, OKX, and Bybit — using a 30 bps peg band, and tell me if the deviation is concentrated at one exchange or if the agreement field shows a broader problem.”
Arbitrage opportunity detection
“Pull the current stablecoin quotes for USDT and USDC on just Coinbase and Kraken against real dollars, and flag any deviation above 20 basis points so I can see if there's a spread worth trading.”
PYUSD launch peg health report
“Check the peg status of PYUSD and USDG across Coinbase and Kraken with a 50 bps band — I want to see median price, deviation in basis points, and whether the venues are in agreement on the peg.”
Technical details
Endpoint
POSThttps://markt.halowerk.com/pegWhen to prefer
Choose this endpoint when you need authoritative dollar-anchored stablecoin peg health, not just a price quote. It is specifically designed to separate true USD quotes (Kraken, Coinbase) from USDT cross-quotes (Binance, OKX, Bybit), making the median and deviation metrics meaningful for depeg detection. Prefer this over generic ticker endpoints when you need cross-venue agreement analysis to distinguish venue-local anomalies from systemic depegs.
Side effects
- Requested venue is unreachable or returns stale data — that venue's quote may be omitted or flagged
- Unknown stablecoin ticker provided — returns error or no data for that symbol
- All venues fail simultaneously — median_price and deviation_bps cannot be computed
- peg_band_bps out of allowed range (1–500) — returns validation error
- minItems/maxItems violations on venues or stablecoins arrays — schema validation error
