Coinbase AgentKit ActionProvider for KnowMint — lets AgentKit agents discover and purchase human tacit knowledge on-chain.

Install

npm install @knowmint/agentkit-plugin

Quick Start

import { AgentKit } from "@coinbase/agentkit";
import { knowmintProvider } from "@knowmint/agentkit-plugin";

const agentkit = new AgentKit({
  actionProviders: [
    knowmintProvider({
      apiKey: "km_...", // Get from https://knowmint.shop/settings/api-keys
    }),
  ],
});

Actions

Action	Description
km_search	Search knowledge items by query, content type, metadata, and sort order
km_get_detail	Get details and preview content for a knowledge item
km_purchase	Record a purchase after sending payment on-chain
km_get_content	Retrieve full content (returns payment instructions if unpaid)
km_publish	Create and publish a new knowledge item

Autonomous Purchase Flow

1. km_search("solana defi")           → item list
2. km_get_detail("item-id")           → details + price (0.01 SOL) + seller_wallet
3. km_get_content("item-id")          → 402: payment_required with payTo address
4. native_transfer(payTo, "0.01")     → tx_hash  (AgentKit built-in action)
5. km_purchase("item-id", tx_hash)    → purchase recorded
6. km_get_content("item-id")          → full content
