CooperLabs B2B API Reference & Schema Guide

Production documentation for our RapidAPI Hub and direct K3s edge endpoints. Every endpoint is backed by a background-warmed Redis cache cluster on Kubernetes and returns enriched sales intelligence, executive summary analytics, and ready-to-send outbound hooks.

Base URLs & Redis Cache Control

Requests can be routed either through the RapidAPI Hub Proxy (for managed billing, rate limiting, and team keys) or directly via our Cloudflare Zero Trust Kubernetes ingress. Every endpoint accepts an optional bypass_cache query parameter: when false (default), cached responses return in <25ms; when true, the engine performs a fresh live crawl and updates Redis.
