Chowbus

Chowbus is a Chicago-headquartered restaurant technology company founded in 2016 by Linxin Wen and Suyu Zhang. It began as an online food ordering, payment and delivery marketplace for Asian restaurants and has since pivoted to a cloud-based, AI-assisted restaurant operating platform: point of sale, self-ordering kiosks, handheld and tablet ordering, kitchen display systems, waitlist and reservations, online ordering, branded restaurant websites and mobile apps, loyalty, gift cards, SMS marketing, a promotions engine, multi-location management, and an AI suite covering digital ads, social media, creative assets and review insights. Chowbus states it serves 9,000+ restaurants across all 50 U.S. states and Canada with 24/7 bilingual (EN/ZH/ES) support, and raised an $81M growth round in March 2026 led by Prysm Capital and Left Lane Capital. Its POS advertises two-way third-party delivery integration with 45+ marketplaces (DoorDash, Uber Eats, Grubhub and others), and partner-side aggregators such as Deliverect publish Chowbus POS connectors — but as of August 2026 Chowbus publishes no public developer portal, API reference, OpenAPI/AsyncAPI contract, SDK, or sandbox. Its only machine-readable public agent surface is a hand-authored bilingual llms.txt at chowbus.com/llms.txt; a JSON API host (pos-api.chowbus.com) is live and returns a structured error envelope but is undocumented and gated.

Chowbus is profiled on the APIs.io network. Tagged areas include Company, Restaurant, Point-of-Sale, Restaurant Technology, and Food and Beverage.

Chowbus’ developer surface includes pricing, signup flow, engineering blog, product news, and 15 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/chowbus: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
