What is Orthogonal?

Orthogonal is an API layer for AI builders that routes agent requests through one endpoint so teams can call verified third-party services without stitching together separate vendor accounts, SDKs, or dashboards. It offers One key, Pay per request, Verified providers, and a catalog spanning Google Search, LinkedIn, Slack, and Gmail. Customers and builders like MouseCat, Hobbes, Claude Code, Cursor, and Codex use it in production workflows.

What does Orthogonal do?

Orthogonal routes agent requests through a single endpoint so builders can call many verified APIs without stitching together separate vendor accounts, SDKs, or dashboards. Its TypeScript SDK, CLI, MCP server, and REST API all use the same request shape, and the platform returns structured responses with usage and pricing on every call. The catalog spans go-to-market data, web search, browser automation, enrichment, and programmatic inboxes, so an agent can search, enrich, scrape, or reach out from one workflow. At scale, the platform advertises 210M+ contacts and 30M+ companies through Apollo, plus dozens of providers across the catalog. Orthogonal says setup can take under 60 seconds, and every verified API is tested, monitored, and uptime-tracked by its team. Customers and builders like MouseCat, Hobbes, Claude Code, Cursor, and Codex use it to keep agent workflows consistent while swapping providers behind the scenes.

Why use Orthogonal?

  • One key replaces provider-by-provider onboarding, which reduces credential sprawl and setup overhead.
  • Verified APIs are tested, monitored, and uptime-tracked, so teams can rely on a managed provider layer.
  • The same request shape works across SDK, CLI, MCP, and REST, which makes switching surfaces easier.
  • Structured responses include usage and pricing on every call, giving agents immediate cost visibility.
  • The catalog covers search, enrichment, browser automation, and inbox workflows, so teams can keep more of the stack in one place.

Who is Orthogonal for?

  • AI product teams who want to call multiple providers through one consistent interface.
  • GTM engineers who need enrichment, search, and outreach data in agent workflows.
  • Developers building Claude Code, Cursor, or Codex integrations that need MCP-native APIs.
  • Automation teams who want browser, search, and data APIs without vendor-by-vendor setup.
  • Operators who need structured responses and per-call pricing in production workflows.

What are Orthogonal's key features?

One key

Use one API key across providers, so agents can switch tools without managing separate credentials or auth flows.

Pay per request

Pay only for each request, with pricing as low as $0.01 per call, which keeps usage costs tied to actual agent activity.

Auth & keys, handled

Let Orthogonal manage authentication and provider keys for you, reducing setup work and avoiding brittle secret handling across integrations.

Verified providers

Call verified providers through a single API, giving agents a vetted path to services instead of wiring each source separately.

Built for agents

Designed for agent workflows, with 60 seconds to first call so teams can move from setup to execution quickly.

Framework-agnostic

Works across agent frameworks and coding environments, including Claude Code, Cursor, and Codex, so teams can adopt it without rewriting workflows.

Browse the catalog

Browse a catalog of verified APIs and services, including Google Search, LinkedIn, Slack, and Gmail, to match tools to agent tasks.

Search by what your agent needs to do

Search by task instead of vendor name, helping teams find the right API for actions like enrichment, search, messaging, or scheduling.

What are Orthogonal's use cases?

AI product teams unify providers

AI product teams who want to call multiple providers through one consistent interface use Orthogonal to route requests without rebuilding integrations each time. They rely on One key and Verified providers to keep production calls predictable, while Pay per request keeps spend tied to actual usage.

GTM enrichment in agents

GTM engineers use Orthogonal to pull enrichment, search, and outreach data directly into agent workflows. With Search by what your agent needs to do and Browse the catalog, they can assemble the right data source quickly and keep lead research moving inside automation.

MCP-native integrations for builders

Developers building Claude Code, Cursor, or Codex integrations use Orthogonal to connect MCP-native APIs without stitching together vendor-specific auth. Built for agents and Framework-agnostic help them ship workflows that work across tools while Auth & keys, handled removes setup friction.

Browser and data automation

Automation teams use Orthogonal to add browser, search, and data APIs to workflows without vendor-by-vendor setup. They combine Verified APIs with Pay only for what you call to run repeatable automations and keep costs aligned with each request.

How does Orthogonal work?

  1. Browse the catalog and Search by what your agent needs to do, then pick the provider or workflow that matches your task. Use Featured Skills or All Skills to narrow the options fast.
  2. Connect with One key so your agent can reach multiple providers through a single setup. Auth & keys, handled keeps credentials out of your workflow logic.
  3. Send your first request through the API and let Pay per request meter usage automatically. Verified providers and Verified APIs help keep responses dependable in production.
  4. Install one command for Reusable skill.md modules when you want a ready-made workflow. Ship the workflow into Claude Code, Cursor, or Codex without rewriting the integration layer.
  5. Monitor calls as your agents run, then expand to new tools from the catalog as needs change. Built for agents and Framework-agnostic keep the same interface across projects.
