# CBAM De Minimis Threshold Tracker

> CBAM De Minimis Threshold Tracker is a paid API for AI agents from reg.chainverdict.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Tracks a year's worth of import lines against the CBAM 50-tonne de minimis threshold and flags the retroactivity trap, where crossing the threshold pulls all in-scope imports for that year into scope, while correctly excluding electricity and hydrogen from the count.

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 cbam-de-minimis-threshold-tracker-73749a27 -d '<json body>'
```

Example prompt: Check my year-to-date CBAM import lines and tell me if I'm approaching or have crossed the 50-tonne de minimis threshold — I need to know if the retroactivity trap has been triggered, pulling all my earlier in-scope imports into full CBAM scope, and note that none of my lines are electricity or hydrogen.

## When to prefer this

Choose this endpoint when you need to evaluate whether a full year of CBAM import lines collectively exceeds the 50-tonne de minimis exemption and whether the retroactivity rule has been triggered — it is specifically designed to handle the chronological compounding logic that means exceeding the threshold at any point brings earlier imports into scope. Prefer it over simple per-shipment CN code lookups (also available on this provider) when you need year-level aggregate threshold analysis with correct exclusion of electricity and hydrogen.

## Known failure modes

- Missing or malformed import line data returns a validation error
- Electricity or hydrogen lines included in the count return a warning with corrected totals
- Ambiguous CN codes that cannot be confirmed as CBAM in-scope return an error requiring clarification
- Incomplete date information prevents correct chronological retroactivity analysis
- Empty import list returns threshold status as zero tonnes with no retroactivity risk

## How this service works

Track a year of import lines against the CBAM 50-tonne de minimis and catch the retroactivity trap: crossing the threshold at any point pulls every in-scope import that year into scope, not just the excess. Electricity and hydrogen never benefit from the de minimis and are excluded from the count.

## Output

Returns the cumulative tonnage of in-scope CBAM imports for the year, the current threshold status (under or over 50 tonnes), whether the retroactivity trap has been triggered (and which import caused the crossing), the list of imports now pulled in-scope as a result, and confirmation that electricity and hydrogen lines were excluded from the calculation.
