Your agent. Your tools. Your control.

Your custom agent,
wired to your tooling.

APIgent gives you a single AI agent you can connect to the APIs, services and data you actually use — then swap the model underneath to find what performs best. No generic chatbots. No leaked context. Just you, in control.

Stay

In control

Built for two kinds of moments.

Whether you're shipping an internal agent for your team, or pressure-testing your own APIs against frontier models — APIgent is the same surface for both.

Pillar 01

Your custom agent, in your control

Skip generic chatbots that don't know your stack. Wire APIgent to your APIs and SaaS tools, and you've got an internal agent that actually understands your business — without shipping your data to someone else's model playground.

  • Choose exactly which tools the agent can call
  • Scope context to the spaces and APIs you trust
  • Switch the underlying model without rewiring tools
Pillar 02

Test how models interact with your APIs

See how different models actually use your endpoints — before you commit them to a product. APIgent runs the same connected tools across Claude, GPT, Gemini and more, so you can compare behaviour, cost and reliability head-to-head.

  • Run identical tool sets across multiple models
  • Catch tool-call mistakes that only show up in production
  • Validate that your API surface is actually LLM-friendly

The full toolkit

Everything you need to build, evaluate, and trust an agent that actually uses your tools.

Connect anything

Plug in your APIs, internal services, and third-party SaaS. The agent treats them all as first-class tools.

Tools, your way

Define each tool's name, schema, and scope. The agent only ever does what you let it do.

Swap models freely

Run the same setup against Claude, GPT, Gemini — pick the best model per workspace, not per project.

See every call

Inspect every tool invocation, payload and response. No black boxes — you see exactly what the agent did.

Spaces for context

Isolate projects, teams or clients in dedicated spaces. Each one gets its own tools, history and model.

Yours, full stop

Your APIs stay yours. Your conversations stay yours. APIgent is the surface — you keep the substance.

From zero to wired in minutes.

01

Connect a tool

Point APIgent at an API or service. Define the operations the agent can call — and the ones it can't.

02

Pick your model

Choose Claude, GPT, Gemini, or run side-by-side. Change your mind any time without touching your tools.

03

Talk to it like you would a teammate

Ask the agent to use your tooling. Watch it work. Adjust scope and re-run. That's the whole loop.

Take control of your AI stack.

Stop testing agents in a vacuum. Wire APIgent to your tools, pick the model that fits, and ship something you actually understand.
