## API — public JSON API

Free, read-only JSON API over the whole archive. No API key, CORS open (`Access-Control-Allow-Origin: *`). Human-readable docs: https://cdn.miners.tools/en/api/

Base URL: `https://cdn.miners.tools/api/v1/`

- `GET /api/v1/manufacturers` — manufacturers + counts
- `GET /api/v1/{manufacturer}/models` — models for a manufacturer
- `GET /api/v1/{manufacturer}/{model}/firmware/list` — firmwares for a model; each entry has `download` (302 API endpoint) and `direct` (direct file URL), both absolute
- `GET /api/v1/{manufacturer}/{model}/firmware/download/{firmware}` — 302 redirect to the file

`{manufacturer}` is one of `bitmain`, `innosilicon`, `whatsminer`, `vnish`.

## Concepts

- **Controllers** (Whatsminer): `h616` (modern miners, M30+), `h3` / `h6` / `h6os` (legacy M10–M23). Pick SD images by controller, not by miner model.
- **Control boards** (VNISH): `aml` / `bb` / `xil` / `cv` — pick the VNISH build matching the board inside your Antminer.
- **Release lines**: `REL2` (latest stable, recommended for new installs), `REL` (previous stable, still supported), `NeedUpgradeAgain` / `NEEDUPGRADEAGAIN` (migration builds — only install when following an official upgrade path; otherwise can brick).
- **Variants**: `normal` (standard), `liquid` (liquid-cooling), `middle` / `full` (Whatsminer internal markers).
- **SHA256 verification**: every firmware page lists its SHA256. Direct downloads from `/downloads/{manufacturer}/...` — no third-party redirects.

## Optional

_Secondary context — safe to skip if a shorter file is needed._

- [Downloads](https://cdn.miners.tools/downloads/): Files at `/downloads/{manufacturer}/...` — free, served as-is, `X-Robots-Tag: noindex` on binaries
- [Languages](https://cdn.miners.tools/en/): Every URL in 6 languages (en, ru, zh, es, pt, de) with `hreflang`
