Per-impression CO₂e for the advertising you serve or verify — the ad-tech emissions, measured, not estimated from spend.
Benchmark
Compare against publisher and format baselines and an industry benchmark — see where a campaign's footprint concentrates.
Report
Pull CSRD/ESRS-ready figures — carbon (E1) and water (E3), plus the trajectory over time — straight into disclosures or client reports.
Every figure traces to a transparent, framework-aligned method. We're pursuing alignment with the Ad Net Zero Global Media Sustainability Framework, the GHG Protocol Scope 3 standard, and IAB Tech Lab measurement guidelines. Coverage today: display and video. See the methodology
What does the Lumotraq ad-carbon API do?
It returns the measured carbon and water footprint of digital advertising as JSON: per-impression CO₂e, per-publisher and per-format breakdowns, attribution, and CSRD/ESRS-ready reporting. It's a measurement and reporting layer — read-only, never part of the bid.
How do I authenticate to the Lumotraq API?
Public aggregate endpoints (industry baselines, KPI summaries, quarterly reports) need no key. Per-account reporting uses an x-api-key header tied to your account, with weekly request limits by plan.
Can AI agents call Lumotraq?
Yes — the API is described in OpenAPI 3.1, listed in a .well-known/api-catalog, and documented for agents, so autonomous systems can discover and query ad-carbon data directly.
How is the Lumotraq API priced?
Consumption-based — you pay per measured impression, not per token, with Buy-Side and Sell-Side tiers. Request access for specifics.
