Overview
When to use Orthogonal
Orthogonal is listed for Data, Payment, Deployment workflows. Orthogonal gives agents one key and a unified interface for discovering and calling verified third-party APIs. Developers can use its REST API, MCP server, CLI, or installable agent skills while Orthogonal handles metering and per-call payments. Consider it when an agent needs this capability through a documented service boundary instead of custom infrastructure maintained inside the application.
In 4agent's task model, the product maps to web extraction, deployment, workflow automation. That makes it a candidate for workflows that research the web, manage memory and knowledge, build and deploy software, operate production agents.
Integration checklist
