  description: >-
    Agent Gateway authenticates, authorizes, and audits the requests agents send
    to models, tools, and other agents. Each gateway runs as a dedicated
    instance on the account's
    [*Network*](https://developers.telnyx.com/docs/network/overview). This API
    creates, lists, and deletes instances, and manages the keys, teams, spend
    logs, MCP servers, APIs, tool permissions, and guardrails on them. Each
    instance serves an OpenAI-compatible API at its `gateway_url`.
