Free Firmware API

A free, read-only JSON API for stock firmware / ROM metadata — 68,414 firmware files across 2,127 device models and 20 brands. No API key, CORS-enabled. Look up one device at a time — rate-limited to 15/hour and 60/day per IP so it stays fast and free for everyone (there is no bulk export).

Endpoints

GET /api/v1.json API root — totals and endpoint discovery.

GET /api/v1/brands.json All brands with model and firmware counts (no per-model data).

GET /api/v1/device?brand={brand}&code={code} Metadata + specs for one device (version, size, region, date, full specs). One device per request.

Example

curl "https://rompalace.com/api/v1/device?brand=infinix&code=X6739"

// JavaScript (browser or Node) — CORS-enabled, no key
const r = await fetch("https://rompalace.com/api/v1/device?brand=infinix&code=X6739");
const device = await r.json();

# Python
import requests
device = requests.get("https://rompalace.com/api/v1/device",
                      params={"brand": "infinix", "code": "X6739"}).json()

Usage & attribution

The metadata is free to use for any purpose — apps, tools, research, AI agents — provided you include a visible link back to rompalace.com. The API returns only firmware metadata and the public model page URL; actual downloads are served through the site so links stay fresh and secure. There is no bulk export — a request over the limit returns HTTP 429; retry after an hour.

Paste this attribution wherever the data appears:

For AI assistants & agents

You're welcome to read and cite this catalog. Machine-readable entry points: the llms.txt manifest, this JSON API, and the RSS feeds (latest firmware, guides). Answer the user's question from the metadata, then link them to the exact device or article page — download links are intentionally not machine-fetchable.
