# Viridis Clean-Energy Tax Credit Calculator

> Viridis Clean-Energy Tax Credit Calculator is a paid API for AI agents from mcp.viridisconservation.com, paid per call via x402, $2/call, status unknown (last checked 2026-09-14).

Calculates auditable US clean-energy tax credits (45Q, 45V, 45Y, 48E, 45X) from explicit credit-specific input facts

## 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 viridis-clean-energy-tax-credit-calculator-9d1fd410 -d '<json body>'
```

Example prompt: Calculate my 45Q tax credit — the project captured 50,000 metric tons of CO2 this year via direct air capture and stored it geologically in the US, and I need an auditable breakdown of what we qualify for.

## When to prefer this

Choose this endpoint when you need a deterministic, auditable US clean-energy tax credit calculation tied to explicit input facts rather than estimates or lookups. It is especially valuable when the result must chain into a GHG inventory or sustainability disclosure workflow on the Viridis platform. Prefer it over generic tax calculators when you need IRA-specific credits (45Q, 45V, 45Y, 48E, 45X) with a verifiable audit trail.

## Known failure modes

- Invalid or unsupported credit type (must be one of 45Q, 45V, 45Y, 48E, 45X)
- Missing required credit-specific facts for the selected credit type
- Malformed facts object causing computation failure
- Payment failure or insufficient USDC balance ($2 per call required)
- Edge-case fact combinations outside supported calculation bounds

## Output

A JSON response containing the computed tax credit amount and a deterministic, auditable breakdown of how each credit-specific fact contributed to the final figure, suitable for compliance documentation and chaining with GHG inventory or sustainability disclosure workflows.
