If you build software services, you’ve probably run into this problem: you’ve built something great, but your monetization options are limited. You’re either charging monthly fees, running ads, or if you really nail it, using Firebase or Supabase as the backend for paid features.

But have you ever thought that an AI Agent might come directly to you to buy your API?

Now you actually can do that.

AgenticTrade is an API marketplace specifically for AI Agents to discover and purchase APIs. It runs on the MCP protocol (Model Context Protocol)—in plain terms: an AI Agent can walk in, find your API, complete authentication, call it, and pay you—all automated, without any human intervention.

The key here isn’t “someone’s using it,” it’s “your API now has a 24/7, passive income monetization channel.” AI Agents don’t sleep, don’t get tired, and won’t forget to pay. As long as people are building AI products, your API has a chance of being used.

Here’s my actual test—a 5-minute process to get an API listed.

Step 1: Register an AgenticTrade Account

First, go to agentictrade.io and click “Sign Up.”

Register with your email, fill in your name and password, and you’ll land on the Dashboard. The top navigation has Dashboard, Services, Analytics, Referrals, and Settings. New users will see a guided Wizard right when they enter—we’ll use that in Step 2.

Step 2: List Your API Using the Guided Wizard

This is where AgenticTrade really shines. With old-school API hosting platforms, you’d click around一堆設定頁面、研究文件、搞半天才知道要從哪裡下手。AgenticTrade 新的 Wizard 把它變成一個 3 步驟的引導表單：

第一步：API Info

  • API 名稱（例如 “Text Summarizer API”）
  • 簡短描述（Agent 會讀這個來決定要不要用你的 API）
  • Endpoint URL（你的 API 對外網址，https:// 開頭）
  • 分類——AI / Machine Learning、Crypto / DeFi、Data & Analytics、Media & Content、Developer Tools

第二步：Pricing

  • 每次呼叫的價格（USDC 計價），建議先看下一段的定價策略
  • 免費 Tier 次數（建議設 100 次，讓 Agent 先試用再決定要不要付費）
  • Tags（方便被搜尋到，用逗號分隔）

第三步：Confirm

  • 預覽你填的所有資訊
  • 確認沒問題，按下「List My API」就上架了

就這樣，3 步。從進 Wizard 到 API 上架，2 分鐘可以搞定。

Step 3：沒有 API？用 Template API 5 分鐘建立一個

這裡是給還沒有自己 API 的人看的。如果你已經有可用的 API，這段可以直接跳過。

AgenticTrade 的 GitHub 上有一個 examples/template_api/ 資料夾，裡面是一個最基本的 FastAPI 專案，裡面只有一個 /predict endpoint，會回傳你 post 過去的資料再加上一些簡單的處理。

流程大概是這樣：

Fork 這個 template

去 github.com/judyailab/agent-commerce-framework 找到 examples/template_api/，Fork 到你自己的帳號。

修改 /predict endpoint

打開 main.py，找到 /predict 函式，把裡面的邏輯換成你自己的。例如你是做天氣資料的，就可以在這裡串你的天氣 API；做影像辨識的，就換成你的模型推論程式碼。這個 template 的設計就是讓你替換一個地方就好，其他的全部照舊。

部署到 Railway 或 Render（免費方案）

Railway 和 Render 都有免費額度，FastAPI 的剛好可以跑。把 Fork 後的 repo 接到 Railway，設定好 uvicorn main:app 啟動指令，等個一兩分鐘，你就有一個可對外存取的 API URL 了。

把這個 URL 複製，回 AgenticTrade 填進 Wizard 的 Endpoint 設定，就完成一個可以上架的 API 了。從零開始到這裡，5 分鐘是可以做到的。

Step 4：定價策略建議

定價是讓很多人卡住的問題。我的建議是這樣的：

如果你做的是通用型工具 API（例如天氣、匯率、基本 NLP），$0.01 - $0.05 / call 是比較合理的區間。這個價格對 AI Agent 的使用者來說幾乎無感，但量跑起來之後其實滿可觀的。

如果你的 API 有比較深的 domain knowledge 或差異化（例如專門做區塊鏈鏈上分析的、醫療文獻摘要的），$0.5 - $2 / call 也有人埋單。重點是你的 API 要足夠稀缺，Agent 才會願意付這個價。

另外，一定建議設定一個 100 次免費 tier。原因很簡單：AI 開發者在決定要用哪個 API 之前，一定會先試跑個幾次確認格式對不對、延遲可不可以接受。如果你沒有免費 tier，他可能直接跳過去找下一個了。

Step 5：查看 Analytics，等 AI Agent 來買

API 上架之後，Dashboard 的「Analytics」頁面會即時顯示幾個重要數字：

  • 總呼叫次數：有多少次實際被用到了
  • 成功 / 失敗率：你的 API 穩不穩定，這個數字很重要
  • 收益：累積了多少錢、什麼時候可以提領
  • 流量來源：哪些 AI Agent / 應用在用你的 API

AgenticTrade 每一筆成功的呼叫都會自動以 USDC 結算收益。佣金結構是這樣的：首月零佣金，第 2-3 個月 5%，第 4 個月起 10%。對比 RapidAPI 抽 25%，這個數字算是友善很多。

我自己在測試這個流程的時候，最驚訝的是從 API 上架到第一筆收益產生的速度。傳統的 API 變現平台，你需要自己行銷、自己找客戶、自己處理付款問題。AgenticTrade 這裡的邏輯完全不一樣——你只需要把 API 放上去，演算法會自動推薦給相關的 AI Agent，不需要你做任何推廣動作。

當 API 被需要的時候，錢自己會來。

對了，首月上架有 Founding Seller 特權，零佣金之外還有一些早期功能優先使用權。如果本來就有 API 或打算做一個，現在這個時間點進場算是比較划算的。

有興趣的話直接去 agentictrade.io 看看，試用不用錢。 the template to your own use case. If you’re working with weather data, connect your weather API here; if you’re doing image recognition, swap in your model inference code. The template is designed so you only need to replace one place—everything else stays as is.

Deploy to Railway or Render (Free Tier)

Both Railway and Render have free tiers that can run FastAPI. Connect your forked repo to Railway, set the startup command to uvicorn main:app, wait a minute or two, and you’ll have a publicly accessible API URL.

Copy that URL, go back to AgenticTrade, paste it into the Wizard’s Endpoint setting, and you’ve got an API ready to list. From zero to here, you can do it in 5 minutes.

Step 4: Pricing Strategy Recommendations

Pricing trips up a lot of people. Here’s my advice:

If you’re building a general-purpose tool API (like weather, exchange rates, basic NLP), $0.01 - $0.05 / call is a reasonable range. That’s almost imperceptible to AI Agent users, but when volume picks up, it adds up.

If your API has deeper domain knowledge or differentiation (like blockchain on-chain analysis, medical literature summarization), $0.5 - $2 / call can work. The key is your API needs to be scarce enough that Agents are willing to pay.

Also, definitely set a 100-call free tier. Reason is simple: AI developers will always test an API a few times to confirm the format is right and latency is acceptable before committing. If you don’t have a free tier, they might just skip to the next one.

Step 5: Check Analytics and Wait for AI Agents to Buy

After your API is listed, the Dashboard’s “Analytics” page shows real-time metrics:

  • Total Calls: How many times it’s actually been used
  • Success/Failure Rate: How stable your API is—this number matters
  • Earnings: How much you’ve accumulated and when you can withdraw
  • Traffic Sources: Which AI Agents/apps are using your API

AgenticTrade automatically settles earnings in USDC for every successful call. The commission structure: zero commission for the first month, 5% for months 2-3, and 10% starting from month 4. Compared to RapidAPI’s 25%, this is pretty friendly.

When I tested this process myself, what surprised me most was how fast revenue came in after listing. With traditional API monetization platforms, you need to do your own marketing, find your own customers, and handle payment issues yourself. The logic at AgenticTrade is completely different—you just list your API, the algorithm automatically recommends it to relevant AI Agents, no promotional work needed on your part.

When the API is needed, the money comes on its own.

Oh, and listing in the first month comes with Founding Seller perks—zero commission plus early access to some features. If you already have an API or plan to build one, this is a pretty good time to jump in.

If you’re interested, just head to agentictrade.io and take a look—trying it out is free.
