tdm-mastra

Make Mastra tools payable with TDM.

This package keeps the Mastra developer experience intact:

• build a normal Mastra tool with createTool(...)
• add the TDM payment fields
• authorize through POST /authorize
• run the original tool logic only after TDM allows it

Install

npm install tdm-mastra tdm-sdk @mastra/core zod

Example

import { z } from "zod";
import { createTdmMastraTool } from "tdm-mastra";

export const premiumResearchTool = createTdmMastraTool({
  baseUrl: process.env.TDM_GATEWAY_URL!,
  apiKey: process.env.TDM_API_KEY,
  id: "premium-research",
  description: "Run a paid research action after TDM authorization.",
  inputSchema: z.object({
    topic: z.string().min(1),
  }),
  outputSchema: z.object({
    summary: z.string(),
  }),
  execute: async ({ topic }) => {
    return {
      summary: `Research summary for ${topic}`,
    };
  },
});

Input shape

Every tool created by createTdmMastraTool(...) includes these TDM fields:

• tokenOrUuid
• operation
• resourceId?
• priceUsd?

Your own schema is merged into that base shape.

Notes

• This package uses the public TDM contract behind POST /authorize.
• It avoids private gateway or treasury logic.
• For lower-level control, use tdm-sdk/make-payable directly.
