Tool overview
Orthogonal is listed under Programming AI tools.
What is Orthogonal?
Orthogonal gives AI agents one interface for discovering, calling, and paying for external APIs. It combines a unified API, MCP and SDK access, per-request pricing, shared credits, routing, analytics, and provider integrations so developers can add data and actions without negotiating separate accounts for every service.
Best for
Agent developers needing many external APIs through one billing layer

Publishing APIs for agent developers
Pros
- Removes separate vendor billing for many APIs
- Publishes transparent per-request economics
- Supports several agent-friendly interfaces
Limitations
Orthogonal simplifies access and billing, but developers must still validate each provider’s data quality, licensing, latency, availability, privacy, compliance, and downstream-use restrictions before relying on an API in production.
