### Create a Custom Endpoint with Access and Source Layers

Source: https://github.com/thirdweb-dev/insight-blueprint-starter/blob/main/README.md

Demonstrates how to register a new GET endpoint using the `Access` layer, define request parameters with Zod validation, handle custom errors, query blockchain transactions using the `Source` layer, and transform the response data. This example fetches transactions for a given contract address on a specified chain.

```typescript
const access = new Access();

// ----------------- Register an endpoint -------------------
access.registerEndpoint({
  path: "/chains/:chainId/contracts/:address/transactions",
  method: "get",
  request: {
    params: z.object({
      chainId: z.string(),
      address: z.string().refine((val) => /^0x[a-fA-F0-9]{40}$/.test(val), {
        message: "Invalid EVM address",
      }),
    }),
  },
  response: z.object({ data: z.array(z.object({ hash: z.string() })) }),
  handler: async ({ params }) => {
    const source = new Source();
    if (params.chainId === "mumbai") {
      // ----------------- You can return custom errors -------------------
      throw new BlueprintAccessError("Chain not supported", 400);
    }
    // ----------------- Define the query you want to make to Insight -------------------
    const transactions = await source.transactions.get(params.chainId, {
      filters: {
        to_address: params.address,
      },
      orderBy: {
        field: ["block_number"],
        direction: "desc",
      },
      pagination: {
        limit: 10,
      },
    });
    // ----------------- Do any data transformations you'd like and return a response -------------------
    return { data: transactions.data.map((tx) => ({ hash: tx.hash })) };
  },
});

// ----------------- Start the server -------------------
access.start();
```

### Clone Insight Blueprint Starter Repository

Source: https://github.com/thirdweb-dev/insight-blueprint-starter/blob/main/README.md

Clones the thirdweb Insight Blueprint Starter repository from GitHub and navigates into the project directory.

```bash
git clone https://github.com/thirdweb-example/insight-blueprint-starter
cd insight-blueprint-starter
```

--------------------------------

### Register a Basic Endpoint with Access Layer

Source: https://github.com/thirdweb-dev/insight-blueprint-starter/blob/main/README.md

Illustrates the fundamental process of registering a new HTTP endpoint (`/my-endpoint`) using the `Access` layer. It shows how to define the path, HTTP method, request query parameters with Zod, and the expected response structure.

```typescript
const app = new Access();

app.registerEndpoint({
  path: "/my-endpoint",
  method: "get",
  request: {
    query: z.object({
      address: z.string(),
    }),
  },
  response: z.object({
    data: z.array(z.any()),
  }),
  handler: async ({ query }) => {
    // Your endpoint logic here
    return { data: [] };
  },
});
```

--------------------------------

### Query Blockchain Data Using Source Layer

Source: https://github.com/thirdweb-dev/insight-blueprint-starter/blob/main/README.md

Shows how to use the `Source` layer to fetch blockchain events and transactions. It demonstrates filtering by address, block number, and pagination for events, and filtering by `from_address` for transactions across different chains.

```typescript
const source = new Source();

// Fetch events
const events = await source.events.get("ethereum", {
  filters: {
    address: "0x...",
    block_number: { operator: "gte", value: 1000000 }
  },
  pagination: { limit: 100 }
});

// Fetch transactions
const txs = await source.transactions.get("polygon", {
  filters: {
    from_address: "0x..."
  }
});
```

### Configure thirdweb Client ID Environment Variable

Source: https://github.com/thirdweb-dev/insight-blueprint-starter/blob/main/README.md

Sets the `THIRDWEB_CLIENT_ID` environment variable with your thirdweb API key. This key is essential for authenticating with thirdweb services.

```bash
THIRDWEB_CLIENT_ID=your_api_key
```

### Implement a Custom Data Transformation Class in TypeScript

Source: https://github.com/thirdweb-dev/insight-blueprint-starter/blob/main/README.md

This snippet demonstrates how to define a custom data transformation class in TypeScript. It shows the basic structure of a class implementing the `Transformation` interface, requiring an asynchronous `transform` method to process `SourceData` into `ResultData`.

```typescript
class MyTransformation implements Transformation<SourceData, ResultData> {
  async transform(data: SourceData): Promise<ResultData> {
    // Transform the data
    return transformedData;
  }
}
```
