Provider Usage Examples

Setup

First, create a Terramind provider instance:

import { createTerramind } from "terramind/provider"

const terramind = createTerramind({
  apiKey: process.env.TERRAMIND_API_KEY,
})

Text Generation

Simple Text Generation

Generate a single text response:

import { generateText } from "ai"

const result = await generateText({
  model: terramind("claude-sonnet-4-5"),
  prompt: "Write a function to reverse a string in TypeScript",
})

console.log(result.text)

With System Message

Add context with a system message:

const result = await generateText({
  model: terramind("claude-sonnet-4-5"),
  system: "You are an expert TypeScript developer who writes clean, maintainable code.",
  prompt: "Write a function to debounce user input",
})

Multi-turn Conversation

Have a conversation with message history:

const result = await generateText({
  model: terramind("claude-sonnet-4-5"),
  messages: [
    { role: "user", content: "What is React?" },
    { role: "assistant", content: "React is a JavaScript library for building user interfaces..." },
    { role: "user", content: "How do I create a component?" },
  ],
})

Streaming

Stream Text

Stream responses in real-time:

import { streamText } from "ai"

const result = await streamText({
  model: terramind("claude-sonnet-4-5"),
  prompt: "Explain quantum computing",
})

for await (const chunk of result.textStream) {
  process.stdout.write(chunk)
}

Stream with Full Response

Access both streaming and final result:

const result = await streamText({
  model: terramind("gpt-5"),
  prompt: "Write a poem about programming",
})

// Stream the response
for await (const chunk of result.textStream) {
  process.stdout.write(chunk)
}

// Get full response with metadata
const fullResponse = await result.response
console.log("\n\nTokens used:", fullResponse.usage)

Object Generation

Generate Structured Data

Create type-safe structured output:

import { generateObject } from "ai"
import { z } from "zod"

const result = await generateObject({
  model: terramind("claude-sonnet-4-5"),
  schema: z.object({
    name: z.string(),
    age: z.number(),
    hobbies: z.array(z.string()),
    address: z.object({
      street: z.string(),
      city: z.string(),
    }),
  }),
  prompt: "Generate a random person profile",
})

console.log(result.object.name) // Type-safe access

Stream Objects

Stream objects as they’re generated:

import { streamObject } from "ai"
import { z } from "zod"

const result = await streamObject({
  model: terramind("claude-sonnet-4-5"),
  schema: z.object({
    tasks: z.array(z.object({
      title: z.string(),
      completed: z.boolean(),
    })),
  }),
  prompt: "Generate a todo list for a software project",
})

for await (const partialObject of result.partialObjectStream) {
  console.log(partialObject)
}

Tool Calling

Single Tool

Define and use a single tool:

import { generateText, tool } from "ai"
import { z } from "zod"

const result = await generateText({
  model: terramind("claude-sonnet-4-5"),
  prompt: "Calculate 25 * 37",
  tools: {
    calculator: tool({
      description: "Perform mathematical calculations",
      parameters: z.object({
        operation: z.enum(["add", "subtract", "multiply", "divide"]),
        a: z.number(),
        b: z.number(),
      }),
      execute: async ({ operation, a, b }) => {
        const ops = {
          add: a + b,
          subtract: a - b,
          multiply: a * b,
          divide: a / b,
        }
        return ops[operation]
      },
    }),
  },
})

console.log(result.text)

Multiple Tools

Use multiple tools together:

const result = await generateText({
  model: terramind("claude-sonnet-4-5"),
  prompt: "Get the weather in Tokyo and convert the temperature to Fahrenheit",
  tools: {
    getWeather: tool({
      description: "Get current weather for a city",
      parameters: z.object({
        city: z.string(),
      }),
      execute: async ({ city }) => {
        // API call
        return { temp: 20, unit: "celsius" }
      },
    }),
    convertTemp: tool({
      description: "Convert temperature between units",
      parameters: z.object({
        value: z.number(),
        from: z.enum(["celsius", "fahrenheit"]),
        to: z.enum(["celsius", "fahrenheit"]),
      }),
      execute: async ({ value, from, to }) => {
        if (from === "celsius" && to === "fahrenheit") {
          return (value * 9/5) + 32
        }
        return value
      },
    }),
  },
})

Tool Call Results

Access tool call information:

const result = await generateText({
  model: terramind("claude-sonnet-4-5"),
  prompt: "Search for TypeScript tutorials",
  tools: {
    search: tool({
      description: "Search the web",
      parameters: z.object({ query: z.string() }),
      execute: async ({ query }) => {
        return ["Result 1", "Result 2"]
      },
    }),
  },
})

// Check if tools were called
for (const toolCall of result.toolCalls) {
  console.log("Tool called:", toolCall.toolName)
  console.log("Arguments:", toolCall.args)
  console.log("Result:", toolCall.result)
}

Advanced Usage

Retry Logic

Implement retry logic for failed requests:

async function generateWithRetry(prompt: string, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await generateText({
        model: terramind("claude-sonnet-4-5"),
        prompt,
      })
    } catch (error) {
      if (i === maxRetries - 1) throw error
      await new Promise(resolve => setTimeout(resolve, 1000 * (i + 1)))
    }
  }
}

Cost Tracking

Track token usage and costs:

const result = await generateText({
  model: terramind("claude-sonnet-4-5"),
  prompt: "Explain machine learning",
})

console.log("Usage:", {
  promptTokens: result.usage.promptTokens,
  completionTokens: result.usage.completionTokens,
  totalTokens: result.usage.totalTokens,
})

Abort Requests

Cancel long-running requests:

const controller = new AbortController()

setTimeout(() => controller.abort(), 5000) // Abort after 5 seconds

try {
  const result = await generateText({
    model: terramind("claude-sonnet-4-5"),
    prompt: "Write a long essay",
    abortSignal: controller.signal,
  })
} catch (error) {
  if (error.name === "AbortError") {
    console.log("Request was aborted")
  }
}

Framework Integration

Next.js App Router

Use in Next.js server actions:

// app/actions.ts
"use server"

import { createTerramind } from "terramind/provider"
import { generateText } from "ai"

const terramind = createTerramind({
  apiKey: process.env.TERRAMIND_API_KEY!,
})

export async function generateContent(prompt: string) {
  const result = await generateText({
    model: terramind("claude-sonnet-4-5"),
    prompt,
  })
  
  return result.text
}

Next.js API Routes

Create an API endpoint:

// app/api/chat/route.ts
import { createTerramind } from "terramind/provider"
import { streamText } from "ai"

const terramind = createTerramind({
  apiKey: process.env.TERRAMIND_API_KEY!,
})

export async function POST(req: Request) {
  const { messages } = await req.json()
  
  const result = await streamText({
    model: terramind("claude-sonnet-4-5"),
    messages,
  })
  
  return result.toDataStreamResponse()
}

Express.js

Use with Express:

import express from "express"
import { createTerramind } from "terramind/provider"
import { generateText } from "ai"

const app = express()
const terramind = createTerramind({
  apiKey: process.env.TERRAMIND_API_KEY!,
})

app.post("/api/generate", async (req, res) => {
  const { prompt } = req.body
  
  const result = await generateText({
    model: terramind("claude-sonnet-4-5"),
    prompt,
  })
  
  res.json({ text: result.text })
})

app.listen(3000)

Best Practices

Cache Provider Instance

Reuse the provider instance across requests:

// lib/ai.ts
import { createTerramind } from "terramind/provider"

export const terramind = createTerramind({
  apiKey: process.env.TERRAMIND_API_KEY!,
})

// Use in multiple files
import { terramind } from "@/lib/ai"
import { generateText } from "ai"

const result = await generateText({
  model: terramind("claude-sonnet-4-5"),
  prompt: "Hello",
})

Environment Variables

Store sensitive data securely:

# .env.local
TERRAMIND_API_KEY=your_key_here

Never commit API keys to version control!

Error Boundaries

Wrap AI calls in error boundaries:

async function safeGenerate(prompt: string) {
  try {
    return await generateText({
      model: terramind("claude-sonnet-4-5"),
      prompt,
    })
  } catch (error) {
    console.error("AI generation failed:", error)
    return { text: "Sorry, I couldn't generate a response." }
  }
}
