Agri Halowerk Carbon Stock Calculator is a paid API for AI agents from agri.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).
Converts soil area, sampling depth, bulk density, and initial/final organic carbon percentages into soil carbon stock estimates and a gross CO2-equivalent difference using the stock-difference method.

How this service works
Converts area, sampling depth, bulk density and initial/final organic-carbon mass fractions into stock estimates and a gross CO2-equivalent difference. This is a simple stock-difference calculation; it does not establish additionality, permanence, leakage, sampling representativeness, credit eligibility or verified carbon removal.
Output
Returns soil carbon stock values (likely in tonnes of carbon per hectare and total), plus a gross CO2-equivalent difference computed from the initial and final organic carbon fractions applied across the specified area and depth. Does not include additionality, permanence, leakage, or credit eligibility assessments.
Example use cases
Farmland carbon baseline assessment
“I need to establish a carbon baseline for my 1200-hectare farm. Sampling depth is 20 cm, bulk density is 1350 kg/m3, and our initial organic carbon reading is 1.8%. What's the starting carbon stock in CO2 equivalent?”
Post-intervention carbon gain estimation
“We ran a regenerative agriculture program on 750 hectares over two years. Bulk density is 1100 kg/m3, sampling depth 25 cm, initial organic carbon was 1.5% and it's now 2.2%. How much CO2 equivalent did we sequester?”
Small plot carbon stock comparison
“For a 5-hectare research plot, sampled at 15 cm depth with a bulk density of 1400 kg/m3, what is the CO2-equivalent difference if organic carbon went from 3.0% initially down to 2.7% after tillage?”
Technical details
Endpoint
POSThttps://agri.halowerk.com/v1/carbon-captureWhen to prefer
Use this endpoint when you need a fast, deterministic computation of soil organic carbon stocks and gross CO2-equivalent differences from direct soil measurements. Ideal for pre-screening agricultural fields, research calculations, or generating indicative numbers before formal verification. Prefer this over manual calculations or spreadsheet tools when integrating into an automated pipeline. Do not use if you need verified carbon credits, additionality analysis, or permanence assessment — this endpoint explicitly disclaims those capabilities.
Side effects
- Missing required fields (area_hectares, bulk_density_kg_per_m3, etc.) result in validation errors
- Values outside allowed ranges (e.g. area > 100,000,000 ha or bulk density < 1 kg/m3) are rejected
- Negative carbon differences are returned if final OC% is lower than initial — not an error, just a carbon loss scenario
- No network connectivity or service downtime returns HTTP error codes
