DeepNLP / AI Agent A2Z · Coding

OneKey Agent Gateway is an AI agent gateway from the DeepNLP and AI Agent A2Z team that lets you reach commercial MCP servers, agent APIs, and LLMs through a single access key. Instead of paying for a dozen separate subscriptions for web search, image generation, or financial data, you authenticate once and route calls with credits. It also converts one API into MCP, CLI, Skills, and REST formats, so developers stop maintaining five versions of the same integration.

About OneKey Agent Gateway

What Is OneKey Agent Gateway

OneKey Agent Gateway sits between your agent and the commercial services it needs. You hold one access key, the gateway holds the rest: authentication, routing, and a credit balance that covers usage across 30+ categories and 100+ tools. It's built for teams tired of juggling separate accounts for search, maps, image models, and finance data.

The pitch is simple. You stop paying for dozens of AI services at full price and instead draw from one credit pool at pay-as-you-go rates. The same gateway doubles as a converter, taking a single API and publishing it as MCP, CLI, Skills, or a routed REST endpoint, so your integration doesn't break every time an agent platform changes its format.

There are real limits. Much of the product is aimed at developers comfortable with CLIs and API keys, so a non-technical user won't get far past registering. Pricing stays credit-based, which means your actual monthly cost depends on usage rather than a flat fee, and that's harder to budget. Some commercial endpoints are still rolling out, so coverage varies by category.

Getting Started

  1. Create an account on the AI Agent A2Z platform and generate your OneKey access key from the dashboard.
  2. Install the tooling you need, either npm install -g @aiagenta2z/agtm for package management or npm install -g @aiagenta2z/onekey-gateway for the command line.
  3. Set your key as an environment variable, for example DEEPNLP_ONEKEY_ROUTER_ACCESS, and add the Skills you want with npx agtm skills add aiagenta2z/onekey-gateway.
  4. Route a request through the gateway, such as npx onekey agent google-maps/google-maps maps_search_places '{"query":"..."}', and watch the credit balance update.

Key features

Single Access Key

One key authenticates you across every service the gateway covers, from agent APIs to MCP servers and LLMs. That removes the awkward juggling of separate tokens for search, maps, and finance tools. One secret to store. Not ten.

Credit-Based Usage

You pay as you go from a credit balance rather than committing to each vendor's subscription. It suits sporadic workloads where a flat monthly plan would waste money. Costs track your usage, so heavy months cost more. Simple as that.

API-to-Agent Converter

Register an API once and the platform republishes it as MCP, CLI, Skills, or a routed REST endpoint. Developers keep one stable API and let the gateway produce the formats each agent client expects. Maintenance drops from several SDKs to one. That alone saves weeks.

MCP Router

The MCP router sends your request to a chosen commercial server, such as Google Search, Google Maps, or financial data providers, without a pre-subscription. You spend credits only on what you call. Want to test a provider first? Route a single query and skip the contract.

AI Agent Router

Beyond tools, the gateway routes queries to state-of-the-art agents on demand. You don't need to subscribe to each agent first; the router picks one and bills credits. Comparisons get cheaper to run.

Open Registry and Marketplace

Through AI Agent A2Z, developers register their own agents and APIs, list them with pricing and model availability, and distribute them across app stores and protocols like MCP and UCP. The marketplace hosts 10k+ agents and MCP servers, giving the gateway a broad pool to route to.

Pros and cons

Pros

  • One access key covers agent APIs, MCP servers, and LLMs, which cuts credential sprawl.
  • Credit pricing avoids paying full price for several overlapping subscriptions.
  • The converter turns a single API into MCP, CLI, Skills, and REST, reducing maintenance.
  • Broad reach across 30+ categories and 100+ tools, so most common needs are covered.

Cons

  • Setup assumes developer skills, since you work through CLIs, API keys, and environment variables.
  • Credit-based billing makes monthly costs harder to predict than a flat plan.
  • Coverage per category still varies as commercial endpoints roll out, so some tools may be missing.

Frequently asked questions

It's an AI agent gateway that connects your agent to commercial MCP servers, agent APIs, and LLMs through a single access key. You use it to route calls, consolidate subscriptions, and convert one API into multiple agent formats.

Forefront · Coding

Forefront is a web platform for building with open-source AI. It lets you fine-tune leading open-source language models on your own data, evaluate how they perform, and run them through an API or export them to host yourself. Developers who want the convenience of a closed-source platform but insist on owning their models and data are the target audience here.

StartKit.AI · Coding

Startkit is a boilerplate for building AI SaaS and AI wrapper products. Think of it as an AI startup boilerplate with the boring parts already wired up: authentication, Stripe and Lemon Squeezy payments, usage limits, transactional email, and an AI API starter that talks to OpenAI, Anthropic, Groq, or Llama. You clone the repo, set your price, and start on the part of your product that people actually pay for. It's Next.js under React and Tailwind, so most of the boilerplate code already feels familiar.

Testim is an AI-powered test automation platform for building and running end-to-end tests across web, mobile, and Salesforce applications. It leans on machine learning to keep tests stable when an interface changes, so teams spend less time fixing broken selectors. Not bad for an automated testing tool you can start using today. You create tests by recording actions in a browser, then optionally add JavaScript when you need more control. It's a solid pick for busy QA teams.
