Code Examples

Copy-paste examples in cURL, JavaScript, Python, and Go.

Basic Screenshot

Capture a simple PNG screenshot of any URL:

curl -X POST https://api.getsnap.dev/v1/screenshot \
  -H "X-API-Key: sk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://github.com",
    "format": "png"
  }'

const response = await fetch("https://api.getsnap.dev/v1/screenshot", {
  method: "POST",
  headers: {
    "X-API-Key": "sk_live_YOUR_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    url: "https://github.com",
    format: "png",
  }),
});

const data = await response.json();
console.log(data.url); // CDN URL to your screenshot

import requests

response = requests.post(
    "https://api.getsnap.dev/v1/screenshot",
    headers={
        "X-API-Key": "sk_live_YOUR_KEY",
        "Content-Type": "application/json",
    },
    json={
        "url": "https://github.com",
        "format": "png",
    },
)

data = response.json()
print(data["url"])  # CDN URL to your screenshot

package main

import (
    "bytes"
    "encoding/json"
    "fmt"
    "net/http"
)

func main() {
    body, _ := json.Marshal(map[string]interface{}{
        "url":    "https://github.com",
        "format": "png",
    })

    req, _ := http.NewRequest("POST",
        "https://api.getsnap.dev/v1/screenshot",
        bytes.NewBuffer(body))
    req.Header.Set("X-API-Key", "sk_live_YOUR_KEY")
    req.Header.Set("Content-Type", "application/json")

    resp, _ := http.DefaultClient.Do(req)
    defer resp.Body.Close()

    var result map[string]interface{}
    json.NewDecoder(resp.Body).Decode(&result)
    fmt.Println(result["url"])
}

Full Page Capture

Capture the entire scrollable page, not just the viewport:

curl -X POST https://api.getsnap.dev/v1/screenshot \
  -H "X-API-Key: sk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://stripe.com/docs",
    "format": "png",
    "full_page": true,
    "remove_popups": true
  }'

const data = await fetch("https://api.getsnap.dev/v1/screenshot", {
  method: "POST",
  headers: {
    "X-API-Key": "sk_live_YOUR_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    url: "https://stripe.com/docs",
    format: "png",
    full_page: true,
    remove_popups: true,
  }),
}).then(r => r.json());

console.log(data.url);

response = requests.post(
    "https://api.getsnap.dev/v1/screenshot",
    headers={"X-API-Key": "sk_live_YOUR_KEY", "Content-Type": "application/json"},
    json={
        "url": "https://stripe.com/docs",
        "format": "png",
        "full_page": True,
        "remove_popups": True,
    },
)
print(response.json()["url"])

PDF Generation

Generate a PDF of any webpage — perfect for invoices, reports, or archival:

curl -X POST https://api.getsnap.dev/v1/screenshot \
  -H "X-API-Key: sk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://invoice.example.com/inv-001",
    "format": "pdf",
    "full_page": true
  }'

const { url } = await fetch("https://api.getsnap.dev/v1/screenshot", {
  method: "POST",
  headers: {
    "X-API-Key": "sk_live_YOUR_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    url: "https://invoice.example.com/inv-001",
    format: "pdf",
    full_page: true,
  }),
}).then(r => r.json());

// url contains the CDN link to the generated PDF

Mobile Device Emulation

Capture as seen on a mobile or tablet device:

curl -X POST https://api.getsnap.dev/v1/screenshot \
  -H "X-API-Key: sk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://tailwindcss.com",
    "format": "webp",
    "device": "mobile",
    "quality": 90
  }'

const data = await fetch("https://api.getsnap.dev/v1/screenshot", {
  method: "POST",
  headers: {
    "X-API-Key": "sk_live_YOUR_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    url: "https://tailwindcss.com",
    format: "webp",
    device: "mobile",
    quality: 90,
  }),
}).then(r => r.json());

Element Capture (CSS Selector)

Capture a specific element on the page using a CSS selector:

curl -X POST https://api.getsnap.dev/v1/screenshot \
  -H "X-API-Key: sk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://getsnap.dev",
    "format": "png",
    "selector": "#pricing .price-card.featured"
  }'

const data = await fetch("https://api.getsnap.dev/v1/screenshot", {
  method: "POST",
  headers: {
    "X-API-Key": "sk_live_YOUR_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    url: "https://getsnap.dev",
    format: "png",
    selector: "#pricing .price-card.featured",
  }),
}).then(r => r.json());

Custom CSS Injection

Inject custom CSS before capture — hide elements, change styles, or highlight sections:

curl -X POST https://api.getsnap.dev/v1/screenshot \
  -H "X-API-Key: sk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://news.ycombinator.com",
    "format": "png",
    "css": "header { display: none; } body { padding-top: 0; }",
    "full_page": false
  }'

Dark Mode

Trigger dark mode on sites that support prefers-color-scheme:

curl -X POST https://api.getsnap.dev/v1/screenshot \
  -H "X-API-Key: sk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://github.com",
    "format": "png",
    "dark_mode": true
  }'

Binary Response (Direct Download)

Get the raw image bytes instead of a CDN URL. Useful for processing or immediate display:

# Save directly to a file
curl -X POST https://api.getsnap.dev/v1/screenshot \
  -H "X-API-Key: sk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://example.com",
    "format": "png",
    "response_type": "binary"
  }' \
  --output screenshot.png

import { writeFile } from "fs/promises";

const response = await fetch("https://api.getsnap.dev/v1/screenshot", {
  method: "POST",
  headers: {
    "X-API-Key": "sk_live_YOUR_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    url: "https://example.com",
    format: "png",
    response_type: "binary",
  }),
});

const buffer = Buffer.from(await response.arrayBuffer());
await writeFile("screenshot.png", buffer);
console.log("Saved screenshot.png");

response = requests.post(
    "https://api.getsnap.dev/v1/screenshot",
    headers={"X-API-Key": "sk_live_YOUR_KEY", "Content-Type": "application/json"},
    json={
        "url": "https://example.com",
        "format": "png",
        "response_type": "binary",
    },
)

with open("screenshot.png", "wb") as f:
    f.write(response.content)
print("Saved screenshot.png")
