About Orthogonal
Summary
Orthogonal builds a unified payments and access layer for AI agents that need to call external APIs. Agents connect through a single key, discover the right endpoint from a catalog of 60-plus providers, and pay per call, replacing the manual work of managing provider accounts, authentication, and billing across dozens of services. API providers list once and collect revenue each time an agent hits their endpoint.
Business model
Pay-per-call usage drawn from a shared balance, with no subscriptions required.
Go-to-market
Developers and agent builders adopt the product self-serve via a unified API, MCP server, or CLI, and add it directly to their applications or coding-agent workflows.

Agentic Payments for APIs
APIs weren't built for agents. Orthogonal fixes that. We enable agentic payments so any agent can instantly discover, access, and pay for hundreds of APIs. No subscriptions, no sales calls, just pay per use. API providers list once and get paid every time an agent calls their API.
