For Agents

Capture website screenshots in PNG, JPEG, or WebP with full-page rendering, custom viewports, and S3 upload via a single GET or POST call to /urltoimage.

Quickstart

Get started with ApiFlash Screenshot API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"capture a website screenshot"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Capabilities

What an agent can do with ApiFlash Screenshot API API.

Capture full-page screenshots of any public URL with configurable viewport width, height, and device scale factor

Inject custom CSS and JavaScript before capture to hide cookie banners, dismiss popups, or modify page layout

Render screenshots from a chosen geolocation, timezone, and accept-language to test localized content

Wait for specific CSS selectors or fixed delays to ensure dynamic content has loaded before snapshot

Jentic publishes the only available OpenAPI specification for ApiFlash Screenshot API, keeping it validated and agent-ready. ApiFlash is a screenshot capture service that turns any URL into a PNG, JPEG, or WebP image through a single REST endpoint. The /urltoimage operation supports full-page screenshots, custom viewport dimensions, geolocation emulation, custom CSS and JavaScript injection, ad blocking, and direct upload to S3 or Azure storage. It is well suited for thumbnail generation, social card previews, archival snapshots, and visual regression workflows where pixel-accurate captures of live web pages are required.

Use Cases

Patterns agents use ApiFlash Screenshot API API for, with concrete tasks.

★ Open Graph and social card generation

Generate preview images for links shared on Twitter, Slack, or LinkedIn by capturing the destination URL through ApiFlash's /urltoimage endpoint. The service produces a 1200x630 JPEG in well under a second for cached pages, removing the need to host headless Chrome. Image bytes can be streamed straight to S3 or returned inline so downstream services can attach them as og:image metadata.

Call GET /urltoimage with url=https://example.com/blog/post, width=1200, height=630, format=jpeg, and full_page=false to produce a social preview image.

Visual regression and archival snapshots

Take periodic full-page screenshots of production pages and store them in S3 to detect unintended visual changes between deploys. ApiFlash supports wait_until and wait_for_selector parameters so dynamic content settles before capture, and the s3_access_key_id parameter writes the image directly to your bucket without proxying through your servers. This makes nightly visual diffs feasible without operating a Puppeteer cluster.

POST /urltoimage with url=https://app.example.com/dashboard, full_page=true, wait_for_selector=.chart-loaded, s3_bucket=visual-archive, and s3_key=2026/06/dashboard.png.

Localized rendering for QA

Verify how a site renders for users in different countries by combining the proxy and accept_language parameters with a desired timezone. ApiFlash routes the request through a node in the chosen region so geo-targeted content, currency, and language switches appear in the captured image. This shortens the QA loop for international launches that previously required VPN-based manual checks.

GET /urltoimage with url=https://shop.example.com, proxy=de, accept_language=de-DE, and format=png to verify the German storefront.

Agent-driven web evidence capture

AI agents researching live web content can call ApiFlash through Jentic to attach a verifiable PNG of any source they cite. Because Jentic returns the /urltoimage operation schema on demand, the agent does not need to bundle the ApiFlash SDK and the access key stays in Jentic's vault. The captured image can be passed back to a vision model for further analysis or stored as an audit artefact.

Through Jentic, search 'capture a website screenshot', load the apiflash /urltoimage schema, and execute with url and full_page=true to attach evidence to the agent's answer.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your ApiFlash access_key is stored encrypted in the Jentic vault. Agents call the operation through a scoped Jentic token and the raw access_key is injected on the server side, never appearing in the agent's prompt or logs.

Intent-based discovery

Agents search Jentic for intents like 'capture a website screenshot' and Jentic returns the apiflash.com /urltoimage operation along with its full input schema, so the agent can fill required parameters without reading documentation.

Time to first call

Direct ApiFlash integration takes a few hours to set up the SDK, error handling, and S3 wiring. Through Jentic the same operation is callable in minutes via search, load, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

Urlbox Screenshot API

Competing screenshot API with signed URLs and broader CSS/JS rendering options.

Choose Urlbox when you need signed, cache-friendly URLs that can be embedded in HTML directly without a server-side fetch.

Alternative

Browshot Screenshot API

Older screenshot service supporting many real-device viewports.

Choose Browshot when device-accurate rendering across mobile models matters more than feature breadth.

Complementary

Browserless

Hosted headless Chrome for arbitrary Puppeteer scripts.

Choose Browserless when a screenshot is not enough and the agent needs to run multi-step browser automation before capturing.

FAQs

Specific to using ApiFlash Screenshot API API through Jentic.

Why is there no official OpenAPI spec for ApiFlash Screenshot API?

ApiFlash does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call ApiFlash Screenshot API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up .

What authentication does the ApiFlash Screenshot API use?

The API uses an apiKey passed as the access_key query parameter on every /urltoimage request. When called through Jentic, the access key is stored encrypted in the Jentic vault and injected at execution time, so the raw key never enters the agent's prompt context.

Can I capture full-page screenshots beyond the visible viewport?

Yes. Pass full_page=true to /urltoimage and ApiFlash will scroll the page to its full rendered height and stitch the image. Combine it with width to fix the viewport horizontally, for example width=1280 and full_page=true.

How do I generate an Open Graph image through Jentic?

Run a Jentic search for 'capture a website screenshot', load the apiflash.com /urltoimage operation, then execute with url, width=1200, height=630, and format=jpeg. Jentic returns the binary image bytes which you can upload to your CDN as the og:image.

Does ApiFlash support uploading the screenshot directly to S3?

Yes. The /urltoimage endpoint accepts s3_access_key_id, s3_secret_key, s3_bucket, s3_key, and s3_endpoint parameters. When provided, ApiFlash writes the image to the specified bucket and returns the object URL instead of the raw image bytes.

What are the rate limits for the ApiFlash Screenshot API?

Rate limits are not declared in the OpenAPI spec and depend on your ApiFlash plan tier. Check the dashboard at apiflash.com for the per-minute capture quota associated with your access key, and back off on HTTP 429 responses.
