Editorial interest 77/100 Selection signal · not a rating of the site

A Wisconsin-based independent builder offers pay-per-result JSON APIs for weather, forecast markets, and other public and business data.

Landing page captured for the 2026-10-10 issue.

For: Developers and AI agents needing structured public data
Worth noticing: Weather-market checkers use METAR/NWS readings from the exact settlement station named in market rules.

Field notes

The catalog links to individual APIs and names their source material, including BLS, BEA, the Federal Reserve, Treasury, and Receita Federal data. The builder reports 12 live APIs, more than 2,700 runs, and 270 users on the top API; these are homepage-reported figures. The page says data rows remain the source of truth when its optional Claude-powered METAR feature adds plain-English summaries.
