What you can do

Developers use Lagoon to power search bots, gallery apps, recommendation engines, and data pipelines.

Search in plain English

https://lagoon.io/api/v1/search?nl=solo+girl+on+pixiv+from+march+2025

Type what you're looking for. The API parses platform, date range, tags, artist handles, and sort order from your query. No tag syntax to memorize.

Find artists across platforms

https://lagoon.io/api/v1/artist?handle=sakimichan

Query one handle, get back every linked account across X, Pixiv, DeviantArt, Bluesky, ArtStation, and more. One search, full cross-reference.

Filter and exclude

https://lagoon.io/api/v1/search?nl=hololive+not+from+pixiv+without+watermark

Date ranges, tag categories, platform filters, negations. Combine them naturally in one query, or use explicit parameters for precision.

Build on structured data

https://lagoon.io/api/v1/search?tag=blue_hair&platform=x&limit=20

Every post comes with categorized tags, artist info, platform metadata, and descriptions. Power gallery apps, Discord bots, or recommendation feeds.

Under the hood

Search without learning tag syntax

Type what you're looking for in plain English. The parser extracts platform, artist, dates, tags, rating, and sort order from your text. The response shows exactly how the query was interpreted.

One handle, every platform

Artists are linked across X, Pixiv, DeviantArt, Bluesky, ArtStation, Newgrounds, Tumblr, and Zerochan. Query any handle, get the full profile map.

Semantic similarity

Find visually related posts by ID or text description. Discover artists with similar styles using pre-computed style vectors. No ML pipeline required on your end.

Tag analytics

Tag co-occurrence data with Jaccard similarity scores. See which tags cluster together, build recommendation logic, or analyze franchise and character trends across the index.

Indexed and preserved

New posts are ingested as they're published across all tracked platforms. When source posts are deleted, the metadata stays: tags, descriptions, and artist links remain searchable.

Standard JSON, no SDK

REST endpoints returning clean JSON. CORS enabled for browser use. Authenticate with a single header. Guides for Python, JavaScript, Go, PHP, React, Discord, and Telegram.
