Our take
A unified API marketplace and payment layer for AI agents. Orthogonal gives agents one key to find and pay for hundreds of APIs through MCP or an SDK - no per-provider onboarding, no subscriptions, pay only for the calls an agent makes, with $10 free credits to start. One key replaces dozens. Partners include People Data Labs and Linkup. YC 2026.
Best for
Developers building agents that need to reach many third-party APIs without managing keys and billing.
Pros
- One key for hundreds of APIs via MCP or SDK
- Pay per call, no subscriptions
- $10 free credits to start
- Removes per-provider onboarding and auth
Cons
- Depends on breadth of partner APIs
- Early-stage marketplace
- Adds a layer between agent and provider
How it compares
In the agentic-commerce stack alongside payment rails like Basis Theory, Orthogonal's angle is discovery plus metered payment for the APIs agents consume, rather than card tokenization.
Full review
Orthogonal is where AI agents go to find and pay for APIs. As agents become major consumers of internet APIs, managing accounts, keys, billing and auth across dozens of providers becomes the bottleneck. Orthogonal replaces that with a single key and a marketplace agents can call through MCP or an SDK.
There's no procurement and no provider-by-provider onboarding: agents get instant access to hundreds of APIs, pay only for the calls they make, and start with $10 in free credits and no subscription. The marketplace lists partners including People Data Labs, Linkup, Aviato and ScrapeGraph, and Orthogonal is part of Y Combinator's 2026 batch.
