# Securaw CryptoVar Risk Asset VaR

> Securaw CryptoVar Risk Asset VaR is a paid API for AI agents from www.securaw.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-20).

Computes Monte Carlo Value-at-Risk (VaR) for a single long spot position in BTC, ETH, or SOL using 90 days of historical Kraken returns with a seeded simulation and audit artifact.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability securaw-cryptovar-risk-asset-var-56fe3124 -d '<json body>'
```

Example prompt: What's the 1-day Value-at-Risk for my $50,000 ETH spot position at 99% confidence? Use Securaw CryptoVar to run the Monte Carlo simulation and give me the audit artifact.

## When to prefer this

Choose this endpoint when you need a fast, auditable, single-asset spot VaR estimate for BTC, ETH, or SOL using empirical Kraken return data and Monte Carlo simulation with a verifiable replay artifact. It is ideal for agents performing per-position risk checks, generating compliance artifacts, or feeding risk dashboards. Prefer this over the multi-scenario sibling endpoint when you only need a single volatility scenario, and over the Black-Scholes endpoint when you want a historical-data-driven simulation rather than parametric assumptions.

## Known failure modes

- Invalid asset — only BTC, ETH, SOL are supported; returns validation error
- Exposure value of zero or negative — schema requires exclusiveMinimum: 0
- Confidence out of range (below 0.9 or above 0.999) — rejected with validation error
- Horizon days out of range (below 1 or above 30) — rejected
- Missing or invalid Idempotency-Key header — request rejected
- Payment failure or insufficient USDC balance — 402 Payment Required
- Exposure exceeds maximum (1 trillion) — validation error

## How this service works

CryptoVar risk_asset: single long spot exposure, BTC/ETH/SOL, 90 daily Kraken returns, seeded Monte Carlo VaR and replay artifact. 0.25 USDC. Idempotency-Key header required. No Bitcoin anchoring included.

## Output

Returns a Monte Carlo VaR estimate for the specified crypto asset and exposure, including the simulated loss threshold at the requested confidence level and horizon, a seeded replay artifact for auditability, and metadata about the 90-day Kraken historical return window used in the simulation.
