Tongdun

Tongdun (同盾科技 / Tongdun Technology) is a Hangzhou-based intelligent risk-control and anti-fraud analytics company whose public product presence now operates under the 小盾未来 (Xiaodun Future) brand at xiaodun.com. It uses AI and intelligent-analysis techniques to predict and score fraud and credit risk across consumer lending, banking, insurance, and e-commerce, delivering decisioning, anti-fraud, and risk-management capabilities to financial institutions, small-loan and consumer-finance lenders, auto finance, and internet businesses. Its risk-control services are consumed as enterprise interfaces (风控接口) provisioned behind account registration and sales onboarding; there is no public self-serve developer portal, OpenAPI, or SDK registry surface exposed at this time. This record was surfaced as a portfolio company of Qiming Venture Partners and enriched from the company's live public web presence.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/tongdun: open an issue to ask a question, or submit a pull request to add artifacts.
