How this service works
Agent-SOFR — decentralized USD short-rate benchmark for AI agents. Weighted-median of 7 sources + variance + regime premiums. BNS-calibrated 6-mode classifier on 444k ETH/USDC 5-min bars (λ=1.097 closed-form). Open + IPFS-pinned methodology: agent-sofr-v1.
Output
Returns a JSON object with: annualized USD short rate (%), asset identifier, rate horizon, regime object (6-mode BNS-calibrated classifier), decomposition of rate components, source-level data from 7 aggregated sources, timestamp, and methodology metadata including IPFS-pinned documentation reference.
Example use cases
Example prompt
“What's the current Agent-SOFR USD short rate for a 1-day horizon, including the regime classification and rate decomposition?”
Technical details
Endpoint
GEThttps://regimeshift.xyz/api/v1/rate/sofr/usdWhen to prefer
Use this endpoint when an AI agent needs a credible, decentralized USD short-rate benchmark for DeFi or agent-native financial operations — particularly for pricing collateralized loans, computing hurdle rates, or assessing interest rate regime context. Prefer over centralized rate APIs when decentralization, open methodology, and crypto-native regime awareness are important. The 6-mode regime classifier makes it uniquely suited for risk-adjusted agent lending decisions.
Side effects
- Invalid horizon enum value (not 1h, 1d, or 1w) — returns 400 bad request
- Payment not provided or insufficient (x402 payment required, $0.001 USDC) — returns 402 payment required
- Source data unavailable causing insufficient quorum for weighted median — may return degraded or error response
- Rate limit exceeded — returns 429
- Service unavailable due to on-chain data feed disruption
