Developer Resources
Everything you need to build with FastScreenshotAPI — SDKs, OpenAPI spec, MCP for AI agents, no-code integrations, and full documentation.
Quick start
# Sync screenshot — returns PNG bytes
curl -X POST https://api.fastscreenshotapi.com/v1/screenshot \
-H "X-Api-Key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"url":"https://example.com","format":"png","full_page":true}' \
--output screenshot.pngReplace YOUR_API_KEY with a key from /dashboard/keys.
SDKs & OpenAPI 3.0
Machine-readable spec at /openapi.json. Generate type-safe clients for any language with openapi-generator-cli.
MCP Server for AI Agents
Connect Claude Desktop, ChatGPT, or any MCP-compatible agent to take screenshots through your API key. One config line.
No-code Integrations
Trigger screenshots from Zapier, Make.com, or n8n workflows. Save to Google Drive, S3, Slack, Notion, Airtable — no code required.
API Documentation
Full reference for every endpoint: sync, async, batch, status polling, signed downloads, webhooks, error codes.
Why FastScreenshotAPI for developers
Three response modes
Sync returns image bytes directly. Async queues a job and pings your webhook. Batch enqueues hundreds of URLs in one call.
Render where it matters
Headless Chromium with anti-bot bypass, cookie banner removal, custom viewport, retina, HTML rendering, PDF export, and full page scrolling.
Production-ready
Per-key rate limiting, signed download URLs, S3/R2 upload, priority queue (Business+), and standard 4xx/5xx error codes with X-Quota-* headers.
Generate any SDK
The OpenAPI 3.0 spec works with openapi-generator-cli, Swagger Codegen, or any compatible toolchain.
First-class AI agent support
The MCP server plugs straight into Claude Desktop or any MCP-compatible host — no glue code.
Skip code entirely
The Zapier, Make, and n8n integrations let you trigger screenshots and pipe them anywhere — Drive, Slack, Notion, Airtable.
