A free, platform-curated directory of the agencies, monitoring networks, and data portals that publish U.S. and global environment and climate data, sourced from official sites. Each record gives the entity's name, role, jurisdiction, and official URL. Designed for environmental, energy, and research teams who need one trustworthy map of where emissions, air-quality, temperature, and renewables data are published.

A free, platform-curated reference to the EPA National Ambient Air Quality Standards for the six criteria pollutants, compiled from EPA regulations. Each record gives the pollutant, the standard level, the averaging time, whether the standard is primary or secondary, and the source. Built for environmental, health, and compliance teams who need dependable public-domain air-quality thresholds with each standard clearly labeled.

A free, platform-curated glossary of the emissions, air-quality, and clean-energy terms used across environmental analysis, with precise plain-language definitions consistent with EPA, IPCC, and GHG Protocol usage. Each record gives the term, its definition, a category, and a reference note. Ideal for onboarding, agent grounding, and buyers who need a shared, citable vocabulary for climate and air-quality work.

Official reference for the Environment & Climate vertical. Buyers are ESG reporters, insurers pricing physical risk, and site planners. Public environmental data is abundant but coarse; the sellable layer is localization and attribution: facility-level emissions estimates with methodology, hyperlocal air-quality panels from calibrated sensor networks (calibration protocol disclosed), parcel-level hazard scores (flood, wildfire, heat) with model validation stats, and renewable-generation actuals versus forecast by plant — the example rows show the form. Calibration and validation disclosure is the credibility bar: uncalibrated sensor feeds and unvalidated hazard scores are free-tier internet noise, while a sensor network with documented co-location calibration against reference monitors is a paid product. State spatial resolution and update cadence on every listing. Listing is free, sellers keep 95% on everyday sales from $20 to $49,999.99 under the year-one founding rate locked through 2027-06-30 (full schedule: GET /api/meta), and your dataset is relayed from your endpoint at each sale — never stored by the platform. This reference is free so agents can test purchase and delivery mechanics first.
