One integration. Three lines.
Drop in the SDK, MCP, or REST API. Three lines, and your agent can reach anything in the catalog.
Discover
Your agent describes what it needs. Orthogonal returns the right service.
Call
Same request shape on every provider. No separate accounts or keys to manage, and one balance for all of them.
Pay
Metered to the call. Pay with credits, x402, or MPP, only for what your agent uses.
import Orthogonal from "@orth/sdk";
const orth = new Orthogonal({ apiKey: process.env.ORTHOGONAL_API_KEY });
// discover → call → pay, one request
const result = await orth.run({
api: "apollo",
path: "/v1/people/search",
query: { title: "CTO", limit: 5 },
});
result.usage; // { provider, credits, cost }Everything your agent can reach, in one API.
Every provider, verified.
A curated list — each one tested, monitored, and uptime-tracked by our team.

“Orthogonal lets our agents leverage dozens of providers through a single unified API. Orthogonal handles the integrations, routing, and billing out of the box. It's the backbone of how we give our agents high quality context at enterprise scale.
“In a world where everything is about agents and APIs are king, Orthogonal provides unbeatable value for teams who want to remain on the bleeding edge of what's possible.
“Completely see the potential here…just plug Orthogonal in with a Claude bot + one API key and it's off to the races.
“Orthogonal is one of the highest-leverage tools in our GTM stack. It gives us a clean API for the account and prospect data our team needs, instead of forcing us to stitch together tools, UIs, and Clay tables. It has made our agent-native GTM workflows faster, cleaner, and meaningfully more effective.
“Orthogonal is an AI-native builder's dream. I get search, scrape, and enrichment data from dozens of vendors through one key and one balance instead of managing tons of individual APIs, contracts, and dashboards.
Questions, answered.
It's one integration that lets your agent reach the tools it can't on its own: company data, contact information, real-time web search, financial data, and more. Your agent describes what it needs, and Orthogonal finds the right service, calls it, pays for it, and hands back a real result.
An LLM can only work with what it already knows. Orthogonal lets your agent go get fresh, verified data and actually do things, then pays for each call as it goes. You get answers grounded in real sources, not guesses.
You pay per call, usually a cent or two, and there's no subscription. Verify your phone number and you get $1 in free credits to try things out. Want more free credits? Book a call with one of our founders and we'll add $10.
Book a call →However you build. There's a TypeScript SDK, a REST API, an MCP server for Claude and Cursor, and a CLI, and the same key works across all of them. Most people make their first call in under a minute.
Instead of juggling dozens of raw API keys, you get one account with pooled, managed credentials and a single auditable bill. Every provider is tested and monitored before it goes live.
