Overview

RMBG-2.0 (BRIA) is KeyoAPI’s background-removal API for product photos, portraits, and design assets that must ship with clean alpha. Unlike consumer remove-background websites, this is a developer-metered image matting API on an AI API relay.

E-commerce feeds, creator tools, and print-on-demand flows need reliable cutouts without Photoshop macros. RMBG-2.0 focuses on high-accuracy mattes that survive zoom and marketplace compression. About $0.0068 per request—often cheaper than legacy SaaS background APIs that charge five to twenty cents an image. See /compare for a high-level price comparison row. Teams use it for SKU studio automation, avatar builders, thumbnail pipelines, and design editors; combine with sam3 when you need open-vocabulary masks beyond subject/background.

Call Keyo matting endpoints with model=RMBG-2.0 on POST /v1/images/mattings (multipart image upload), not chat completions. Try it from /pricing/RMBG-2.0. Accept PNG/JPEG, return alpha, soft-fail on tiny images, and offer a preview URL for merchant QA.

Cutout quality in commerce is a reliability problem: hair edges, transparent packaging, and white-on-white SKUs. Build a QA loop that flags leftover background, re-run or escalate to sam3 masks, store alpha PNGs with SKU ids, and curate a regression set of fifty SKUs after every model upgrade.
