Agent infrastructure

An AI agent API needs limits as much as it needs tools

Agent loops can multiply requests quickly. Start with a model that supports tools, then constrain the key and record each request before adding autonomous retries.

Planned recharge methods: Alipay and USDT. Collection is not enabled yet.

Agent-ready controls

  • Model allowlist
  • Tool permission
  • Maximum output tokens
  • RPM, TPM and concurrency limits
  • Daily and monthly budgets

A safe rollout

  • Begin with one tool and deterministic arguments.
  • Validate tool input on your server.
  • Cap loop depth and retry count.
  • Log request IDs and tool outcomes.
  • Require human approval for irreversible actions.

Framework compatibility

Frameworks such as LangChain, CrewAI and other OpenAI-compatible clients can be evaluated through the same base URL. Framework support is not a substitute for testing the actual model and tool schema.

agent-tool.tstypescript
const response = await client.chat.completions.create({
  model: "qwen3.7-plus",
  messages: [{ role: "user", content: "What is the order status?" }],
  tools: [{
    type: "function",
    function: {
      name: "get_order_status",
      description: "Return the current order status",
      parameters: {
        type: "object",
        properties: { order_id: { type: "string" } },
        required: ["order_id"]
      }
    }
  }]
});

Common questions

Which model should I use for an AI agent?

Choose from models that advertise tool support, then test your actual schemas and language requirements. There is no universal best agent model.

Can I stop an agent from overspending?

Use bounded loops in application code and enforce project and API-key budgets, rate limits and concurrency limits at the gateway.

Do I need to change my agent framework?

Many frameworks accept an OpenAI-compatible base URL. Confirm the framework's exact configuration and response expectations in a small test first.
