Quick Start

Install the SDK

The TypeScript SDK wraps the public /v1 API. It ships dual ESM + CJS with bundled types and runs on Node 18+, Bun, Deno, or any runtime with a global fetch.

npm install @seachat/platform-sdk
# or: bun add @seachat/platform-sdk

Create the client

Every request carries a SINGLE credential: Authorization: Bearer <apiKey>. The SDK never also sends x-api-key. The base URL defaults to https://seachat.ai; all paths live under /v1.

import { SeaChat } from "@seachat/platform-sdk";

const client = new SeaChat({ apiKey: process.env.SEACHAT_API_KEY! });

Make your first chat call

client.chat.completions.create posts to /v1/chat/completions (OpenAI-compatible). Pass stream: true to get an AsyncIterable of chunks instead of one result.

const completion = await client.chat.completions.create({
  model: "claude-opus-4-8",
  messages: [{ role: "user", content: "Greet the ocean in one short line." }],
  max_tokens: 64,
});
console.log(completion.choices[0].message.content);

Or call /v1 directly with curl

Every SDK method maps to a plain HTTP route. The same first call over curl, using the same single Bearer credential:

curl https://seachat.ai/v1/chat/completions \
  -H "Authorization: Bearer $SEACHAT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-opus-4-8",
    "messages": [{"role":"user","content":"Greet the ocean in one short line."}],
    "max_tokens": 64
  }'
