# Lumotraq

> Lumotraq is an independent ad-carbon measurement project. We measure the carbon footprint of digital advertising at the per-impression level — replacing modeled industry averages with bottom-up measurement collected by a browser extension and aggregated through a web dashboard. Methodology pursues alignment with Ad Net Zero GMSF v1.2, GHG Protocol, and IAB Tech Lab.

## Methodology

- [How Lumotraq measures ad carbon](https://lumotraq.com/methodology): Full per-impression measurement methodology. Covers device energy benchmarks, electricity-grid intensity attribution by user location, data-centre efficiency factors, format and creative-weight modeling. Includes carbon impact chain, scope inclusions and exclusions, comparison against top-down estimation tools.

- [Viewability vs Attention](https://lumotraq.com/viewability-vs-attention): Why current viewability metrics fail as a proxy for ad carbon — and what attention-based measurement reveals that viewability hides. Argument for measurement at impression level instead of campaign average.

## Ad blockers and measurement

- [AdGuard alternatives](https://lumotraq.com/adguard-alternatives): Comparison of ad blockers (uBlock Origin, AdGuard, Ghostery, AdBlock Plus) against ad-carbon measurement tools. Why blocking and measuring are different problems.

## API & agents

Lumotraq exposes a read-only aggregate ad-carbon reporting API for B2B accounts and autonomous agents (AGaaS Tier 0). Base URL https://api.lumotraq.com/v1. Read-only aggregates only — no ingest, write, admin, or personal data.

- [OpenAPI 3.1 specification](https://api.lumotraq.com/v1/openapi.yaml): Machine-readable description of every endpoint, parameter and response schema. Two auth tiers — public aggregate reads (no key) and per-account reporting (x-api-key header).
- [API catalog (RFC 9727)](https://api.lumotraq.com/.well-known/api-catalog): Service-discovery linkset pointing to the spec, methodology and this file.
- Public endpoints, no key: `/v1/kpi/summary`, `/v1/baseline/creative`, `/v1/baseline/industry`, `/v1/reports/quarterly`. Keyed reporting endpoints cover CSRD/ESRS E1+E3 reports, per-cohort and per-format CO2 and water breakdowns, and media-efficiency trajectories.
