TypeScript
Node examples with @anthropic-ai/sdk and openai, including streaming.
Anthropic SDK
npm install @anthropic-ai/sdkimport Anthropic from "@anthropic-ai/sdk";
const client = new Anthropic({
apiKey: process.env.CLAUDEAPIKEY!,
baseURL: "https:">//aiprimetech.io", // no /v1
});
const msg = await client.messages.create({
model: "claude-sonnet-4-6",
max_tokens: 1024,
messages: [{ role: "user", content: "Explain event loops briefly." }],
});
const block = msg.content[0];
if (block.type === "text") console.log(block.text);content is a discriminated union. Narrow on block.type === "text" rather than indexing blindly — a tool-use reply has no .text and will be undefined at runtime.Streaming
const stream = await client.messages.stream({
model: "claude-sonnet-4-6",
max_tokens: 1024,
messages: [{ role: "user", content: "Count to five." }],
});
for await (const event of stream) {
if (event.type === "content_block_delta" && event.delta.type === "text_delta") {
process.stdout.write(event.delta.text);
}
}
const final = await stream.finalMessage();
console.log(final.usage);OpenAI SDK
import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.CLAUDEAPIKEY!,
baseURL: "https:">//aiprimetech.io/v1", // with /v1
});
const r = await client.chat.completions.create({
model: "claude-sonnet-4-6",
messages: [{ role: "user", content: "Hello" }],
});
console.log(r.choices[0].message.content);Never ship a key in browser-side code. Call the gateway from your server and expose your own endpoint to the front end — anything in a bundle is public.
