docsignal API

A read-only HTTP API returning JSON. Every response is generated from the same event store the daily crawl writes to.

We crawl the public documentation of 25 AI-native software companies every day, diff it, and turn the changes into structured events. Most of what a company ships never reaches its changelog, and those are the changes this exists to catch: quiet limit changes, features moved between pricing tiers, endpoints published without announcement, capabilities withdrawn.
