One endpoint for every model your agent needs
Route between Claude, GPT, Gemini and Codex-style models behind a single API, so agents can pick the right model per step without juggling providers.
AI Agent API
AI Agent API gateway
Tool calling and multi-model routing for agents.
Power AI agents and coding tools with one gateway across Claude, GPT and Gemini. Tool calling, function calling and MCP-style workflows with multi-model routing, failover and usage tracking.
Built for tool calling and MCP
Forward tool-calling and function-calling requests reliably, and pair with MCP-style agent tooling so long-running workflows stay stable.
Observability for agent runs
Per-request logs of model, tokens, latency and cost make it easy to debug agent loops and keep multi-step runs within budget.
Does the gateway support tool/function calling?
Yes. Tool calling and function calling pass through to the upstream model, so agent frameworks work as expected.
Can one agent use multiple models?
Yes. Route different steps to Claude, GPT or Gemini through the same API and keys.
How do I keep agent runs affordable?
Use plans or wallet billing and watch per-request usage logs to control cost across multi-step runs.
