Ariadne Nexus CUSIP, Bond Valuation & FINRA TRACE Finance

Calculates institutional RWA clearing house take-rates (in basis points and USD), cross-chain settlement bridge tolls, platform SaaS subscription fees, and net annual clearing cost projections across Ariadne Nexus membership tiers. Use when: estimating monthly or annual clearing fees, basis-point take-rates, and cross-chain bridge settlement costs before syndicating an RWA vault or selecting an institutional billing tier. Do not use when: provisioning an API key or generating a live Stripe checkout session (use provision_agent_key instead), or valuing bond CUSIPs (use get_cusip_valuation instead). Behavior: Free, open-access, read-only deterministic calculator ($0.00 USD; requires no apiKey or paymentToken and performs no external network calls or billing mutations).

Computes deterministic fair market value (USD), yield-to-maturity (approximate and exact cashflow YTM %), Macaulay and modified duration (years), convexity, DV01 (USD per 1bp shift), and Merton jump-diffusion 95% confidence bounds for a single corporate, sovereign, or RWA fixed-income security. Use when: pricing or analyzing an individual bond CUSIP/ticker given par value, coupon, maturity, and clean market price. Do not use when: scanning FINRA TRACE secondary dealer prints or structuring single-security option collars (use get_debt_radar instead), or running multi-position portfolio macro shocks and VaR/CVaR (use run_portfolio_stress_test instead). Behavior: Read-only, deterministic, side-effect-free calculation ($0.50 USD per call via apiKey or paymentToken; returns an x402/MPP paymentChallenge without charging if credentials are omitted).

Retrieves secondary-market FINRA TRACE dealer execution metrics (last clean price % of par, Z-spread over 10Y U.S. Treasury in bps, effective yield-to-worst %, dealer bid-ask spread in bps, and daily institutional block volume in USD) and solves a Black-Scholes zero-cost 1-year European option collar (put floor strike % and call cap strike %) for a single bond CUSIP or ticker. Use when: inspecting secondary-market dealer liquidity/spreads or structuring a zero-cost downside put / upside call collar for a single bond issue. Do not use when: calculating exact cashflow duration/convexity/DV01 for a custom face value (use get_cusip_valuation instead), or stress-testing a multi-bond portfolio across macro rate shocks (use run_portfolio_stress_test instead). Behavior: Read-only, deterministic market tape and option solver ($0.50 USD per call via apiKey or paymentToken; returns an x402/MPP paymentChallenge without charging if credentials are omitted).

Returns pricing specifications, monthly query quotas, rate limits (RPM), 1-click Stripe Checkout links (starting at $10/mo MCP Builder Pass up to $9,500/yr FAR 13.2 GPC & Unlimited Closing Blanket licenses), Stripe Projects CLI commands (stripe provision ariadnenexus), and optional live Stripe Checkout session URLs (mint_stripe_session: true) for obtaining a live Ariadne Nexus Developer API key (nexus_live_...). Use when: an agent, developer, escrow attorney, or litigation desk needs pricing comparisons or a direct clickable Stripe Checkout URL after encountering a paymentChallenge on paid tools. Do not use when: redeeming an already-paid Stripe Checkout cs_... session ID for its API key (use redeem_checkout_session instead), or estimating basis-point RWA clearing take-rates (use calculate_clearing_fee instead). Behavior: Free discovery and checkout-link generator ($0.00 USD). Does not charge any payment method on invocation; billing only occurs if the human completes payment at the returned Stripe Checkout URL.

Verifies a completed Stripe Checkout session (cs_...) directly against Ariadne Nexus billing and deterministically returns the buyer’s live HMAC-signed nexus_live_... API key, monthly quota, and 1-click Cursor / VS Code / Claude Code installation links. Use when: a user has just completed payment at Stripe Checkout and wants to immediately claim and activate their nexus_live_... API key inside Claude, Cursor, VS Code, or an autonomous agent without waiting for email delivery. Do not use when: the user has not yet paid or needs a checkout link first (use provision_agent_key instead). Behavior: Free, read-only, deterministic verification and HMAC credential derivation ($0.00 USD; idempotent across repeated invocations for the same paid cs_... session ID).

Executes multi-position fixed-income portfolio stress testing across customizable macroeconomic rate shocks (parallel benchmark shifts in bps, rating-weighted credit spread widening in bps, yield curve twists: PARALLEL/STEEPENER/FLATTENER/INVERSION, and liquidity haircuts), computing aggregate portfolio DV01, 1-year 95%/99% parametric Value-at-Risk (VaR), 99% Expected Shortfall (CVaR), position-level P&L attribution, 10-Year Treasury Note futures (ZN) short hedge ratios, and portfolio-wide zero-cost European collar strikes. Use when: stress-testing a multi-bond portfolio under interest-rate or credit-spread shocks, calculating portfolio VaR/CVaR, or sizing 10Y Treasury futures duration hedges. Do not use when: pricing a single bond CUSIP without a macro shock scenario (use get_cusip_valuation instead) or checking single-CUSIP FINRA TRACE dealer prints (use get_debt_radar instead). Behavior: Read-only, deterministic portfolio simulation ($2.50 USD per call via apiKey or paymentToken; defaults to a 3-bond institutional benchmark portfolio if portfolio array is omitted; returns an x402/MPP paymentChallenge without charging if credentials are omitted).
