## Services

- [CryptoVar VaR Artifact Verifier](https://www.zero.xyz/c/cryptovar-var-artifact-verifier-3bdc0b68/llms.txt): $0.1/call via x402. Replays a CryptoVar Black-Scholes VaR calculation from its original parameters and audit proof to confirm the result is authentic and unaltered.
- [Securaw CryptoVar Risk Snapshot](https://www.zero.xyz/c/securaw-cryptovar-risk-snapshot-4e9c3780/llms.txt): $0.25/call via x402. Computes a seeded single-exposure Monte Carlo Value-at-Risk (VaR) using Black-Scholes assumptions and returns a verifiable CryptoVar audit artifact.
- [Securaw TimeChain2 File Timestamp Registration (delivery_proof)](https://www.zero.xyz/c/securaw-timechain2-file-timestamp-registration-delivery-proof-90feaf64/llms.txt): $0.05/call via x402. Registers a file's SHA-256 hash with Securaw/TimeChain2 and returns a downloadable ZIP containing an OpenTimestamps proof, metadata, and independent verification instructions.
- [Securaw TimeChain2 SHA-256 Bitcoin Proof Verification](https://www.zero.xyz/c/securaw-timechain2-sha-256-bitcoin-proof-verification-18118d8c/llms.txt): $0.02/call via x402. Verifies a SHA-256 hash against a Securaw/TimeChain2 event, reporting both registry checks and direct-file Bitcoin timestamp proof separately with downloadable proof when available.
- [Securaw CryptoVar Volatility Scenario Comparison](https://www.zero.xyz/c/securaw-cryptovar-volatility-scenario-comparison-81352abd/llms.txt): $0.5/call via x402. Runs Monte Carlo VaR for 2–3 distinct volatility scenarios on a single exposure and returns each scenario's VaR, delta from the first, and audit/replay proofs.
- [Securaw CryptoVar Execution Stress / Cost Estimator](https://www.zero.xyz/c/securaw-cryptovar-execution-stress-cost-estimator-67021f40/llms.txt): $0.05/call via x402. Computes a total execution cost estimate in basis points from user-supplied spread, fees, market impact, and participation assumptions — no live trading or order book involved.
- [Securaw CryptoVar Risk Asset VaR](https://www.zero.xyz/c/securaw-cryptovar-risk-asset-var-56fe3124/llms.txt): $0.25/call via x402.
