taxcredit-engine
Auditable deterministic US clean-energy tax-credit scenarios for 45Q, 45V, 45Y, 48E, and 45X. Versioned IRS rule packs, exact arithmetic, eligibility flags, audit hashes, and notary-ready proof. **Try it (copy-paste):** `calculate_tax_credit` with `{"credit":"45V","facts":{"tax_year":2026,"kg_hydrogen":"1000","lifecycle_kg_co2e_per_kg_h2":"0.44","greet_version":"45VH2-GREET-2025","pwa_met":true,"produced_in_us":true,...}}` → returns `credit_amount_usd: "3280.00"` with a reproducible `audit_sha256`. **Pricing:** 10 free calls/day, then $2.00/calculation. Pay as a human via Stripe (`create_payment` → `redeem_payment`) or as an agent via x402 escrow: fund an escrow payable to `viridis:taxcredit-engine` at mcp.viridisconservation.com/escrow/mcp, then retry with `payment_ref=<escrow_id>`. The 402 envelope carries full instructions.
