Generate images with a simple API call

Screenshots, OG images, and HTML-to-image rendering. One API, instant results. Built for developers who ship fast.

curl -X POST https://rendly-api.fly.dev/api/v1/screenshots \
  -H "Authorization: Bearer ren_live_abc123" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com", "format": "png"}'

curl -X POST https://rendly-api.fly.dev/api/v1/screenshots \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://github.com/rendly",
    "viewport": {"width": 1280, "height": 720},
    "format": "png"
  }'
const response = await fetch('https://rendly-api.fly.dev/api/v1/screenshots', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json',

  body: JSON.stringify({
    url: 'https://github.com/rendly',
    viewport: { width: 1280, height: 720 },
    format: 'png',
  }),
});

const data = await response.json();
console.log(data.url); // CDN image URL
import requests

response = requests.post(
    'https://rendly-api.fly.dev/api/v1/screenshots',
    headers={'Authorization': 'Bearer YOUR_API_KEY'},
    json={

        'viewport': {'width': 1280, 'height': 720},
        'format': 'png',
    }
)

data = response.json()
print(data['url'])  # CDN image URL
require 'net/http'
require 'json'

uri = URI('https://rendly-api.fly.dev/api/v1/screenshots')
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true

request = Net::HTTP::Post.new(uri)
request['Authorization'] = 'Bearer YOUR_API_KEY'
request['Content-Type'] = 'application/json'
request.body = {
  url: 'https://github.com/rendly',
  viewport: { width: 1280, height: 720 },
  format: 'png'
}.to_json

response = http.request(request)
data = JSON.parse(response.body)
puts data['url'] # CDN image URL
