x402
RegimeShift Max-LTV Calculator is a paid API for AI agents from regimeshift.xyz, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Computes the maximum safe loan-to-value ratio for collateralized agent loans using volatility-regime-aware math, returning the binding constraint (mathematical vs regime cap) and supporting parameters.

How this service works
Maximum-safe LTV for collateralized agent loans. Computed from (cv + λ·j²)-derived variance over loan horizon + 6-mode regime cap. Lender-specifiable max_default_prob. Returns binding constraint (math vs regime_cap) so agents can see WHY the cap is what it is. Same calibrator as Agent-SOFR rate endpoint.
Output
Returns a JSON object with ok (boolean), max_ltv (the binding maximum loan-to-value ratio as a decimal), math_max_ltv (the mathematically derived LTV), regime_cap_ltv (the 6-mode regime ceiling), binding_constraint (string: 'math' or 'regime_cap' indicating which is tighter), sigma_T (projected volatility over the loan horizon), and regime (current market regime label).
Example use cases
Example prompt
“What's the maximum safe LTV I should use for an ETH-collateralized loan lasting 3600 seconds, given I can tolerate at most a 0.5% default probability? I want to know whether the math or the regime cap is the binding constraint.”
Technical details
Endpoint
GEThttps://regimeshift.xyz/api/v1/risk/max-ltvWhen to prefer
Use this endpoint when an AI agent or DeFi protocol needs to set or validate a safe LTV for a collateralized crypto loan and requires both a mathematically derived cap and a regime-based ceiling, along with a clear explanation of which constraint is binding. Prefer this over generic LTV heuristics when the loan horizon is short (2 minutes to 24 hours), the collateral is ETH or BTC, and the lender needs to specify a tolerated default probability. It shares the same volatility calibrator as the Agent-SOFR rate endpoint, making it well-suited for agent lending stacks that already use that benchmark.
Side effects
- Missing required asset parameter returns 400 or empty result
- duration_sec outside 120–86400 range returns validation error
- max_default_prob outside 0–0.01 range is rejected
- Unsupported asset symbol (not ETH or BTC) returns enum validation error
- Upstream volatility or regime data unavailable causes 5xx or degraded response
- Payment not attached or insufficient USDC causes 402 Payment Required
