Node/TypeScript client for ogmake.com: render Open Graph images and PDFs from templates or raw HTML, run batches, sign image URLs locally, and verify webhooks. Zero runtime dependencies; needs Node 18+ (global fetch).

npm i @ogmake/sdk

Quick start

import { createClient } from "@ogmake/sdk";

const ogmake = createClient({ apiKey: process.env.OGMAKE_API_KEY }); // og_live_...

// Render a template (hosted URL back)
const img = await ogmake.renderImage({
  template: "blog-post",
  params: { title: "Hello world" },
  format: "png",
  preset: "og",
});
console.log(img.url);

// Render raw HTML/CSS (2 credits; no JavaScript is executed)
const html = await ogmake.renderHtml({
  html: "<h1>Hello</h1>",
  css: "h1{font:700 64px sans-serif}",
  width: 1200,
  height: 630,
});

// Batch: up to 500 renders, optional signed batch.completed webhook
const batch = await ogmake.createBatch({
  items: [{ template: "blog-post", params: { title: "One" } }],
  webhookUrl: "https://example.com/hooks/ogmake",
});
const status = await ogmake.getBatch(batch.batch_id);

Other methods: renderImageAsync, createBatchCsv, listWebhookDeliveries, listTemplates (no key needed), freeRender (watermarked, no key), getUsage, signImageUrl (HMAC-SHA256, computed locally, secret never sent), publicImageUrl. Helpers: verifyWebhookSignature, ogSnippet.

Sign an image URL locally (no network, the secret is never sent):

const url = await ogmake.signImageUrl("KEY_ID", new TextEncoder().encode("SIGNING_SECRET"), {
  template: "blog-post",
  params: { title: "Hello world" },
  format: "png",
  preset: "og",
});
