API Snap
API Snap is a developer utility platform that consolidates 13+ commonly needed REST APIs into a single, unified service with one API key. The platform provides QR code generation, screenshot capture, image resize and conversion, HTML-to-PDF rendering, Markdown-to-HTML conversion, URL metadata extraction, cryptographic hashing, JWT decoding, Base64 encoding/decoding, UUID and unique ID generation, color format conversion, lorem ipsum text generation, and SVG placeholder image generation. API Snap aims to eliminate dependency bloat by letting developers replace small libraries and self-hosted utility services with simple HTTP requests against a managed, rate-limited, multi-tenant API.

A single Bearer API key (prefix snp_) authorizes all 13+ utility endpoints. No per-service signup or per-product key.
Every endpoint follows a simple REST pattern under https://api-snap.com/api and returns either JSON or the natural binary content type (image, PDF, SVG) for the resource.
All responses include X-RateLimit-Limit and X-RateLimit-Remaining headers so clients can implement adaptive throttling.
Stateless endpoints (hash, qr, uuid, color, meta, lorem, placeholder, screenshot) accept GET with query parameters; mutating endpoints (resize, pdf, markdown, base64, jwt-decode) use POST with a JSON or multipart body.
Replaces multiple small libraries and self-hosted micro-services for QR generation, screenshots, image resizing, PDF rendering, hashing, and ID generation with one HTTP integration.
Image and document endpoints accept multiple input formats (binary, base64, URL) and produce multiple output formats (PNG, JPEG, WebP, AVIF, SVG, PDF, HTML).
Use Cases
Generate trackable QR codes for campaigns, packaging, business cards, and events without integrating a QR library.
Use the URL Metadata API to build rich link previews and bookmark cards in chat apps, CMS platforms, and feed readers.
Capture webpage thumbnails for SEO, social cards, monitoring dashboards, and visual regression checks without operating headless Chromium.
Resize and reformat user uploads on demand for avatars, thumbnails, and responsive images without running an image processing service.
Render invoices, receipts, contracts, and reports as PDF directly from HTML templates.
Centralize UUID, NanoID, and prefixed-ID generation across services without bundling identifier libraries into every codebase.
Convert user or author Markdown into HTML on the fly for blogs, docs sites, and customer-facing UIs.
Decode JWTs in admin tooling and developer utilities to inspect claims, issuers, and expiration without writing per-language decoders.
Generate placeholder images, lorem text, and color conversions inside design tooling, mockup builders, and component playgrounds.
Integrations
Works with any HTTP client (curl, fetch, axios, requests) via the Authorization Bearer header or api_key query parameter.
Drop-in replacement for self-hosted Puppeteer or Playwright services handling screenshot and PDF workloads.
Drop-in replacement for libraries such as sharp or imagemagick when consumed as a managed service.
