Initials avatar (SVG)
API · /placeholder-api
Placeholder API
A fast, fully-local SVG generator for mockups and UIs: placeholder images (a sized rectangle with centered text and automatic contrast), initials avatars (with a deterministic colour derived from the name, in a circle or square), and identicon-style symmetric patterns generated deterministically from any seed. Every endpoint returns the JSON envelope or, with raw=1, the raw SVG so the URL can be used directly as an image source. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for prototypes, dashboards, user avatars, empty states and design systems.

Dog Breeds & Images API
Dog-breed images and the full breed taxonomy via the open Dog CEO collection — no key. The breeds endpoint returns every breed with its sub-breeds (e.g. hound → afghan, basset, blood, …). The images endpoint fetches a batch of photos for a given breed and optional sub-breed, and the random endpoint pulls a batch of random dog photos from across all breeds. Real images straight from the Dog CEO dataset, with the breed list cached for speed — no key. 4 endpoints. Ideal for pet apps, placeholder imagery, breed pickers, quizzes and fun UI seeding.

Lorem Ipsum API
Generate classic Lorem Ipsum placeholder text as an API — exactly as much as you need, in the shape you need. Request a number of words, sentences, paragraphs (as plain text or ready-to-drop-in HTML <p> tags), bullet-list items, or an exact byte length. Prose can start with the canonical "Lorem ipsum dolor sit amet, consectetur adipiscing elit…" or with random Latin. Generated entirely on the server, so it is instant and always available — no third-party calls. Ideal for mockups and design comps, CMS and template seeding, UI prototyping, test fixtures and load-test payloads, and anywhere a layout needs filler copy.

Photos API
Real stock photography as an API, powered by Lorem Picsum. Browse a curated catalogue of high-resolution photos with their author and dimensions, look up any photo by id, or build a ready-to-embed image URL on the fly — pick a width and height and get a random photo, pass a seed for a stable deterministic image (the same seed always returns the same photo, ideal for consistent placeholders per user or item), or target a specific photo by id, with optional grayscale and blur. No accounts, no attribution headaches: every image is a clean, hotlinkable URL. Perfect for mockups and design comps, blog and CMS placeholders, app prototypes, test fixtures and any layout that needs real imagery instead of grey boxes.

Color Palette API
Extract the dominant colour palette from any image. Pass an image URL (we fetch it) or a base64 image and get back its main colours — each as a hex code, RGB triplet and the percentage of the image it covers — plus the single dominant colour and the overall average colour. Choose how many colours to return (1 to 16). The image is decoded and downscaled locally and the colours are quantised on the fly; nothing is stored and there is no third-party service. Supports PNG, JPEG, BMP, TIFF and GIF. Live. 2 endpoints. Built for theming and design tools, auto-generating UI colours from artwork or product photos, brand-colour extraction, and image tagging. Distinct from a single-colour converter or an image resize/info service. No upstream key.
