使用场景
使 SaaS API 对 AI 代理可用
在现有REST API旁边发布agents.json文件，使任何兼容AI代理都可以发现可用的动作并无需自定义集成代码调用它们
定义多步骤API流程
将链式端点调用描述为可重用的 agents.json流程，让代理按预期执行复杂序列而不是通过.prompt来推断
取代易折断.prompt形式工具使用
利用runtime工具库为代理提供声明性的、结构化的工具定义，减少由硬编码工具调用或.prompt设计漂移引起的故障
编写和托管代理规范
团队可以使用平台的编写和托管工具来创建、测试和提供 agents.json文件，类似于管理OpenAPI规范的传统客户端
优点 & 缺点
优点
- 开源并且中立的规范
- 减少依赖于易折断的.prompt形式工具
- 支持多步骤API流程，不仅是单个调用
- 熟悉的模式对于使用OpenAPI而来的团队
- 支持现有API
缺点
- 标准仍然在发展中，尚未普遍接受
- 要求API提供者认真地编写和维护规范
- 比专有函数调用工具要小的生态系统
- 不如专有工具便利

Use it every day
Honestly didn't expect to like it this much. Runtime libraries for agent-side discovery and execution is exactly what I needed, and supports multi-step API workflows, not just single calls. but I reach for it almost every day now and it just clicks.
Years in this space
I've evaluated a lot of these over the years. What stands out here is runtime libraries for agent-side discovery and execution — handled better than most — and familiar pattern for teams already using OpenAPI. Worth the time if this is your use case.
Does the job
Pretty happy overall. Agents.json specification for describing API actions just works and reduces reliance on fragile prompt-based tool use. but no dealbreakers — I'd recommend it to a friend without hesitating.

问答
What are the key benefits?
Benefits include reduced reliance on prompt-based tool use, support for multi-step workflows, and a familiar pattern for OpenAPI users.
Asked by Larisa Ionescu · Mar 10, 2026
Is agents.json production-ready and widely supported?
The specification is open-source and vendor-neutral with reference implementations, but it's still emerging and has a smaller ecosystem than proprietary function-calling tools. It's best suited to developers comfortable adopting early standards for agentic applications.

Is Wildcard AI open-source?
Yes, Wildcard AI is open-source and vendor-neutral.

What problem does it solve?
It reduces reliance on fragile prompt-based tool use and supports multi-step API workflows.
Asked by Quang Nguyen · Dec 18, 2025
What do I need to do as an API provider to support Wildcard AI?
You author and host an agents.json file alongside your existing REST API, describing available actions and workflows. Wildcard provides authoring, hosting, and testing tools, and the spec is compatible with existing REST endpoints and auth schemes, so you don't need to rebuild your API.
