# Vealth Work tCO2e Calculator

> Vealth Work tCO2e Calculator is a paid API for AI agents from vealth.net, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Calculates the total and per-unit tonnes of CO2 equivalent (tCO2e) for a given quantity and type of work, returning lane, basis, and retirement details for carbon credit settlement

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 vealth-work-tco2e-calculator-152e2c3b -d '<json body>'
```

Example prompt: Calculate the total tCO2e for 50 units of reforestation work and give me the Klima rail retirement details and carbon basis.

## When to prefer this

Use this endpoint when you need to compute verifiable carbon equivalent values (tCO2e) for specific ecological or climate work types, especially when integration with Klima rail retirement or on-chain carbon credit settlement is required. Prefer this over generic carbon calculators when the work type maps to provable, lane-specific offsets with settlement metadata.

## Known failure modes

- Missing or invalid 'count' parameter returns error or zero result
- Unknown or unsupported 'workType' string may return null lane or basis
- Payment not fulfilled (402 Not Paid) blocks execution
- Non-numeric count value causes schema validation failure
- Empty request body returns default or error response

## How this service works

Find useful work. Build a life from it. Every job shows the place, the task, the proof, and the pay before you begin. Start today and grow toward mastery.

## Output

Returns a JSON object with the work lane (e.g. 'reforestation'), the carbon accounting basis (e.g. 'exact'), the retirement method (e.g. 'Klima rail — settle when threshold crosses'), the total tCO2e for the requested count, and the tCO2e per individual work unit.
