Why Orthogonal?

Everything you need to build with APIs, without the headaches.

No API keys to manage

One Orthogonal key gives you access to every API in our marketplace. Stop managing dozens of keys.

Pay as you go

No subscriptions, no commitments. Pay only for what you use, with transparent pricing — 2.5% + $0.004 per call. Perfect for prototyping and agents.

Natural language search

"I need an API to scrape websites." Describe what you need and find the right API instantly.

Automatic failover

If an API call fails or times out, your agent can dynamically switch to an equivalent provider. Multiple providers per category ensure uptime.

MCP native

Built from the ground up for AI agents. Works with Claude, ChatGPT, Cursor, and any MCP-compatible tool.

Growing marketplace

Search, scraping, AI models, datasets, weather, social media, and more. New APIs added regularly.
