Overview

Merge provides connective infrastructure for production AI. It is designed to help teams connect products and agents to APIs, tools, and LLMs through a single platform so they can run at scale.

The site presents Merge across product areas including Unified API, Gateway, and Agent Handler. Together they support synced data integrations, governed agent actions, and model routing for teams building AI products and internal workflows.

Features

Unified integration access

Connect products and agents to hundreds of integrations through one API for synced customer data, reducing the need for custom integration maintenance.

Governed agent actions

Deploy agents across enterprise tools with authenticated actions, scoped permissions, and audit logs for controlled execution.

Intelligent model routing

Route LLM requests automatically by cost, latency, or quality, with failover when a provider goes down.

Cost controls and billing visibility

Manage spend with budgets by project, team, or customer tier, plus visibility into cost by model, provider, and team.

Security controls for model traffic

Apply security controls such as DLP, prompt injection protection, per-customer policies, and request logging.

Custom router configuration

Use Merge Gateway's routing presets, benchmark library, scoring rules, and decision transparency tools to define custom routing logic.

Use cases

Enterprise search and retrieval
Continuously sync customer data from supported systems into search or RAG products so responses can be based on fresher source data.
Agent execution across enterprise tools
Let agents take authenticated actions in customer or internal systems while keeping permissions and logs in place.
Model selection and resilience
Route each LLM request to the right provider based on task needs, then fall back if a provider becomes unavailable.
Auto-provisioning workflows
Automatically assign onboarding and permissions using real-time employee data from HR systems.
Operations and finance workflows
Sync bills, payments, and ticketing data to support reconciliation, project tracking, and financial analysis.
