SSE streaming সহ models, generations, files, credits, webhooks এবং Chat-এর জন্য Public API v1 call করতে Rivya TypeScript SDK beta ব্যবহার করুন।

server-side Public API integrations-এর জন্য Rivya একটি TypeScript SDK beta দেয়।

SDK হলো Rivya Public API v1-এর ওপর thin client। lower-level contract এখনও OpenAPI and Schema Contract, এবং SDK methods সেই schema-এর সঙ্গে aligned থাকতে হবে।

Status

package-টি বর্তমানে এই repository-এর ভিতরে private beta হিসেবে maintained। package name, metadata, changelog এবং release process explicitly approved না হওয়া পর্যন্ত এটি npm-এ published নয়।

SDK support করে:

model listing
asynchronous generation create and retrieve
Files API upload and retrieve
credit balance retrieval
webhook endpoint management, test deliveries, event listing, delivery listing এবং secret rotation
webhook signature verification
non-streaming এবং streaming Chat completions, plus API-created chat sessions

Chat streaming এই private beta-তে server-side SSE parsing দিয়ে available। secret API keys আপনার server-এ রাখুন।

Install In This Repo

SDK beta থাকা অবস্থায় local package source ব্যবহার করুন:

pnpm --dir packages/rivya-sdk typecheck

Application code secret API key server-এ রাখবে:

import { RivyaClient } from "@rivya/sdk";

const rivya = new RivyaClient({
  apiKey: process.env.RIVYA_API_KEY
});

secret API keys browser bundles, localStorage, analytics events, screenshots বা shared tickets-এ রাখবেন না।

List Models

models.list public এবং API key দরকার হয় না:

const models = await rivya.models.list();

for (const model of models.data) {
  console.log(model.id, model.api_status, model.supported_api_inputs);
}

Create A Generation

asynchronous image, video বা audio generation-এর জন্য generations.create ব্যবহার করুন:

const generation = await rivya.generations.create(
  {
    model: "z-image",
    prompt: "A clean editorial product image on a soft studio background",
    client_request_id: "order-123-preview"
  },
  {
    idempotencyKey: "order-123-preview"
  }
);

console.log(generation.id, generation.status);

তারপর generations.retrieve দিয়ে poll করুন:

const current = await rivya.generations.retrieve(generation.id);
console.log(current.status, current.result?.primary_url);

production write requests-এর জন্য Idempotency-Key ব্যবহার করুন। SDK এটি idempotencyKey হিসেবে expose করে।

Upload Files

reference images, videos বা audio-এর জন্য files.upload ব্যবহার করুন:

import { readFile } from "node:fs/promises";

const file = new Blob([await readFile("./reference.png")], {
  type: "image/png"
});

const uploaded = await rivya.files.upload({
  file,
  filename: "reference.png",
  kind: "image",
  model: "nano-banana-2",
  client_request_id: "asset-123"
});

console.log(uploaded.id, uploaded.url);

uploaded metadata আবার read করতে files.retrieve ব্যবহার করুন:

const sameFile = await rivya.files.retrieve(uploaded.id);
console.log(sameFile.mime_type, sameFile.duration_token);

generation-এ file ব্যবহার করার সময় returned public fields params.referenceMediaItems দিয়ে pass করুন:

await rivya.generations.create({
  model: "nano-banana-2",
  prompt: "Restyle this product photo for a clean editorial catalog page",
  params: {
    referenceMediaItems: [
      {
        url: uploaded.url,
        kind: uploaded.kind,
        name: uploaded.file_name,
        mimeType: uploaded.mime_type,
        durationSeconds: uploaded.duration_seconds ?? undefined,
        durationToken: uploaded.duration_token ?? undefined
      }
    ]
  }
});

Check Credits

const credits = await rivya.credits.retrieve();
console.log(credits.current_credits);

Manage Webhooks

webhook endpoint create করুন:

const endpoint = await rivya.webhooks.create({
  name: "Production webhook",
  url: "https://example.com/rivya/webhook",
  event_types: ["generation.succeeded", "generation.failed"]
});

console.log(endpoint.id, endpoint.signing_secret);

signing_secret শুধু create বা rotate calls-এর পরে return হয়। এটি আপনার server-এ store করুন।

Other webhook helpers:

await rivya.webhooks.list();
await rivya.webhooks.retrieve(endpoint.id);
await rivya.webhooks.update(endpoint.id, { status: "disabled" });
await rivya.webhooks.test(endpoint.id);
await rivya.webhooks.rotateSecret(endpoint.id);
await rivya.webhooks.deliveries.list(endpoint.id, { limit: 20 });
await rivya.webhookEvents.list({ limit: 20 });

webhook payload trust করার আগে delivery signatures verify করুন:

import { verifyRivyaWebhookSignature } from "@rivya/sdk";

const ok = await verifyRivyaWebhookSignature({
  rawBody,
  timestamp: request.headers.get("rivya-webhook-timestamp") || "",
  signatureHeader: request.headers.get("rivya-webhook-signature") || "",
  signingSecret: process.env.RIVYA_WEBHOOK_SIGNING_SECRET || ""
});

if (!ok) {
  throw new Error("Invalid Rivya webhook signature");
}

SDK helper API Webhooks-এ documented একই HMAC-SHA256 contract ব্যবহার করে।

Chat

একটি non-streaming Chat API turn-এর জন্য chat.completions.create ব্যবহার করুন:

const completion = await rivya.chat.completions.create(
  {
    model: "gpt-5-2-chat",
    message: "Write a concise launch plan for a new product image campaign",
    client_request_id: "chat-001"
  },
  {
    idempotencyKey: "chat-001"
  }
);

console.log(completion.session_id, completion.message.content);

returned session_id দিয়ে continue করুন:

await rivya.chat.completions.create({
  model: "gpt-5-2-chat",
  session_id: completion.session_id,
  message: "Now turn that into a 5-step execution checklist."
});

API-created sessions read করুন:

await rivya.chat.sessions.list({ limit: 20 });
await rivya.chat.sessions.retrieve(completion.session_id);

Server-Sent Events async iterator হিসেবে consume করতে chat.completions.stream ব্যবহার করুন:

const stream = await rivya.chat.completions.stream(
  {
    model: "gpt-5-2-chat",
    message: "Write a concise launch plan for a new product image campaign",
    client_request_id: "chat-stream-001"
  },
  {
    idempotencyKey: "chat-stream-001"
  }
);

for await (const event of stream) {
  if (event.event === "message.delta") {
    process.stdout.write(event.data.delta);
  }

  if (event.event === "message.completed") {
    console.log(event.data.message.id);
  }
}

message.delta শুধু display-এর জন্য। committed result message.completed-এর পরে available হয়, এবং পরে chat.sessions.retrieve দিয়ে read করা যায়।

Errors

non-2xx Public API responses-এর জন্য SDK RivyaAPIError throw করে:

import { RivyaAPIError } from "@rivya/sdk";

try {
  await rivya.generations.retrieve("task_missing");
} catch (error) {
  if (error instanceof RivyaAPIError) {
    console.log(error.status, error.code, error.requestId);
  }
}

RivyaAPIError HTTP status, public error code, message, request id available হলে তা, এবং safe response-header subset অন্তর্ভুক্ত করে।

Validation

change complete ধরে নেওয়ার আগে SDK checks run করুন:

pnpm sdk:check
pnpm --dir packages/rivya-sdk typecheck
pnpm content:api-docs

pnpm sdk:check static contract check এবং no-network runtime check অন্তর্ভুক্ত করে, যেখানে error parsing, safe error headers, idempotency headers, Bearer auth, public model listing, Chat streaming SSE parsing, Chat streaming error events এবং webhook signature verification cover হয়।
