# MyCO2 Suite – Batch EU CBAM Liability Calculator

> MyCO2 Suite – Batch EU CBAM Liability Calculator is a paid API for AI agents from api.myco2suite.io, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-14).

Calculates EU CBAM certificate count and EUR liability for a portfolio of 1–100 shipments in a single call, sharing one live ETS carbon price across all items.

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 myco2-suite-batch-eu-cbam-liability-calculator-b8e068ea -d '<json body>'
```

Example prompt: Calculate the total EU CBAM liability for a batch of 30 steel shipments I'm importing from Ukraine — use the current ETS price and give me the certificate count and EUR cost for each shipment in one go.

## When to prefer this

Use this endpoint when you need to calculate EU CBAM liability for multiple shipments (2–100) in a single API call rather than making individual calls per shipment. It is more cost-efficient and faster than looping the single-shipment endpoint because one live ETS price lookup is shared across the whole batch. Ideal for compliance automation pipelines, freight forwarder quoting tools, or quarterly portfolio-level CBAM exposure reporting.

## Known failure modes

- More than 100 shipments submitted — batch size limit exceeded, returns 400 error
- Invalid or missing embedded emissions data for one or more shipments
- Unsupported CBAM commodity code — returns validation error per shipment
- ETS price feed temporarily unavailable — service may return 503
- Malformed shipment objects in the batch array — partial or full rejection with field-level errors
- Missing importer or country-of-origin data required for CBAM calculation

## How this service works

Batch EU CBAM: liability for a portfolio of shipments in one call (1–100 shipments; a single live ETS price is shared). Priced per shipment.

## Output

Returns per-shipment results including embedded emissions, free-allocation benchmark, CBAM certificates required, and EUR liability, plus an aggregate portfolio total — all computed using a single live ETS carbon price fetched at request time.
