Orthogonal - Agentic Payments for APIs

Sales teams and agents need accurate contact data. Bad emails bounce. Wrong phone numbers waste time. Outdated LinkedIn profiles lead nowhere.

Today we're highlighting Fiber AI, a comprehensive contact data platform now available on Orthogonal.

What is Fiber AI?

Fiber AI delivers verified contact data for people and companies worldwide. Natural language search, real-time LinkedIn enrichment, email validation, and investor databases. All through a single API.

Key Features

Search for people and companies using plain English. "Software engineers in San Francisco with 5+ years experience" returns exactly that.

Real-Time LinkedIn Data

Fetch live LinkedIn profiles, posts, comments, and reactions. Always fresh, always accurate.

Email Validation

Validate email deliverability including catch-all addresses that other APIs miss.

Investor Database

Search for investors by type, investment count, lead rate, and more. Find the right VC for your stage.

const account = privateKeyToAccount(process.env.PRIVATE_KEY);
const fetchWithPayment = wrapFetchWithPayment(fetch, account);

// Validate email with automatic USDC payment
const url = "https://x402.orth.sh/fiber/v1/validate-email/single";
const response = await fetchWithPayment(url, {
