Install

npm install strale-semantic-kernel semantic-kernel

Quick start

import { createStralePlugin } from "strale-semantic-kernel";

const plugin = await createStralePlugin({ apiKey: "sk_live_..." });

// plugin.functions contains 250+ kernel functions
console.log(`Loaded ${plugin.functions.length} Strale capabilities`);

Use with Semantic Kernel

import { Kernel, FunctionChoiceBehavior, functionInvocation } from "semantic-kernel";
import { OpenAIChatClient } from "@semantic-kernel/openai";
import { createStralePlugin } from "strale-semantic-kernel";

const chatClient = new OpenAIChatClient({
  apiKey: process.env.OPENAI_API_KEY!,
  modelId: "gpt-4o",
}).asBuilder().use(functionInvocation).build();

const kernel = new Kernel().addService(chatClient);

const stralePlugin = await createStralePlugin({ apiKey: "sk_live_..." });
kernel.addPlugin(stralePlugin);

const result = await kernel.invokePrompt(
  "Validate the VAT number SE556703748501",
  {
    executionSettings: {
      functionChoiceBehavior: FunctionChoiceBehavior.Auto(),
    },
  }
);

Filter by category

const plugin = await createStralePlugin({
  apiKey: "sk_live_...",
  categories: ["finance", "compliance"],
});

Direct API client

import { StraleClient } from "strale-semantic-kernel";

const client = new StraleClient({ apiKey: "sk_live_..." });

// List all capabilities
const caps = await client.listCapabilities();

// Execute a capability
const result = await client.execute({
  capabilitySlug: "vat-format-validate",
  inputs: { vat_number: "SE556703748501" },
  maxPriceCents: 10,
});

// Check balance
const balance = await client.getBalance();

What's included

Each Strale capability becomes a kernel function with:

• name — capability slug (e.g. vat-validate, swedish-company-data)
• description — what it does + price in EUR
• schema — JSON Schema for parameters
• implementation — calls the Strale API

Plus two meta-functions:

• strale_search — discover capabilities by keyword
• strale_balance — check your wallet balance

Solutions (KYB & Invoice Verify)

// Solutions are discoverable via strale_search
// 81 pre-built solutions: KYB Essentials, KYB Complete, Invoice Verify × 20 countries
const result = await client.execute({
  solution: "kyb-essentials-se",
  inputs: { org_number: "5591674668" },
});

Using Strale in agent system prompts

Add this to your Semantic Kernel agent's system prompt for automatic capability routing:

When you need to verify a business, validate an IBAN or VAT number, screen
against sanctions/PEP lists, extract data from a URL or document, or check
compliance — use your Strale kernel functions. Call strale_search to find
the right capability, then invoke it. Returns structured JSON with quality
scores. 250+ capabilities across 27 countries. Free tier: email-validate,
dns-lookup, json-repair, url-to-markdown, iban-validate (no API key needed).
