Introduction
AI models continue to advance at an extraordinary pace. Performance improves month by month, new architectures emerge rapidly, and the number of available models grows every day.
Yet despite this progress, the way AI is accessed, operated, and integrated has changed very little.
Most teams still build products tightly coupled to a single provider, a single API key, and a single endpoint. As the number of models increases, operational complexity grows alongside it, and risks related to outages, pricing changes, or policy shifts are pushed directly onto applications and users.
AI models are evolving quickly. AI operations are not.
This is not a theoretical observation. The WORLD3 team has been building and operating AI agents continuously in Web3 environments, handling real traffic across multi-chain, multi-protocol, and multi-model systems. These agents are not simple chatbots, but long-running autonomous systems that cannot pause or degrade silently.
Through this experience, one conclusion became clear:
The core problem is not which model to use, but how AI requests flow β and how that flow is structured, optimized, and verified.
RouterLink is not an attempt to build another "better model." RouterLink is an attempt to network AI access itself.
RouterLink is an open routing network for AI. Anyone can operate routing nodes and/or provide model services, while developers and users interact through a unified gateway. Usage-based revenue is measured and settled through verifiable, protocol-level mechanisms.
Market Opportunity
The AI API Economy is Exploding
The AI API market represents one of the fastest-growing segments in technology:
AI API Market Size
$44.4B
$179.1B
32.2% CAGR
Model API Spending
$8.4B

The Problem with Centralized API Gateways
Current market leaders demonstrate both the opportunity and the limitations:
OpenRouter (leading centralized aggregator):
4.2M+ users, 250K+ applications
300+ models from 60+ providers
Raised $40M from a16z, Menlo Ventures
400% annualized revenue growth (2024-2025)

Yet centralized gateways remain fundamentally limited:
Single operator controls routing and policy
Usage metrics are opaque and unverifiable
Settlement is discretionary and off-chain
No protocol-level participation for infrastructure contributors
The Cost of AI Dependency
Enterprise downtime costs are staggering:
Small Business
$1,000 - $5,000
Mid-Market
~$35,000
Enterprise
$100,000+
Recent Outage Impact:
OpenAI December 2024: 6-hour global outage
Claude September 2025: 30-minute outage disrupted enterprise workflows
175+ incidents recorded for major AI providers in 12 months

Multi-provider users saved an average of $25,000+ during the February 2025 OpenAI degradation event.
"The era of single-platform AI dependency is ending."
