懂车帝 Dongchedi

Mode: 🌐 Public · Domain: dongchedi.com

No login, no cookies, no signature. Every command does a plain HTTP GET of a server-rendered page and parses the __NEXT_DATA__ JSON embedded in the HTML, so it works out of the box.

Commands

Command	Description
opencli dongchedi search <keyword>	Search car series by keyword → series + 指导价/经销商价
opencli dongchedi series <series_id>	Series overview: brand, prices, 懂车分, sales rank, trim count
opencli dongchedi models <series_id>	Trims (款型) with guide / dealer / owner prices
opencli dongchedi specs <series_id>	Config overview: dimensions, powertrain, drivetrain, airbags
opencli dongchedi score <series_id>	懂车分 rating — 8 axes vs same-class average
opencli dongchedi koubei <series_id>	Owner reviews (口碑): rating, trim bought, likes, full text

series, models, specs, score, and koubei all take a series_id — get one from search (the series_id column) or paste a https://www.dongchedi.com/auto/series/<id> URL.

Notes & Limits

• Why SSR, not the JSON API: Dongchedi's /motor/... XHR endpoints are ByteDance-signature gated (a_bogus / X-Bogus) and 404 without a valid signature. The SSR pages expose the same data unsigned, so this adapter reads those instead — no signature replication, no breakage when the signing scheme rotates.
• specs is the overview, not the full parameter sheet. The complete per-trim parameter table lives behind a signed XHR; rather than fabricate it, specs returns the unsigned SSR overview (dimensions, powertrain, drivetrain, suspension, airbags). For per-trim names/prices use models.
• koubei is a single SSR page (up to ~15 reviews). Deep pagination uses the signed API and is intentionally not implemented.
