## 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 carbon-tax-auto-withholder-mcp-6c881c62 -d '<json body>'
```

Example prompt: Can you automatically calculate and withhold the appropriate carbon tax from this transaction data: '{"amount": 5000, "fuel_type": "diesel", "quantity_kg": 200}'?

## When to prefer this

Choose this endpoint when you need automated, real-time carbon tax withholding computation embedded in a transaction or data pipeline. Ideal for agentic workflows where carbon compliance must be enforced programmatically without manual calculation. Prefer this over generic tax APIs when the specific use case is carbon emission levies and automatic withholding logic.

## Known failure modes

- Invalid or malformed data string returns a parsing error
- Missing required emission or transaction fields cause computation failure
- Unsupported data format may result in a generic processing error
- Network timeout or service unavailability returns a 5xx error
- Ambiguous data types may produce inaccurate tax calculations

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a processed result indicating the carbon tax amount to be withheld, the adjusted transaction value after withholding, and a breakdown of how the carbon levy was computed based on the input data.
