Numerai

Numerai is a San Francisco hedge fund that crowdsources its stock-market trading models from a global community of data scientists. Participants download obfuscated, regularized financial datasets, train machine-learning models, and submit predictions each weekly round through a single GraphQL API at api-tournament.numer.ai. Models are staked with the Ethereum-based NMR token and earn performance-based payouts for accurate, original signals. The platform spans Numerai Classic, Numerai Signals (bring-your-own stock signals), and Crypto Signals, with official Python tooling (numerapi, numerai-cli, numerai-tools) and cloud Compute Prediction Nodes for fully automated round submissions.

Numerai publishes 1 API on the APIs.io network. Tagged areas include Company, Fintech, Machine-Learning, Data Science, and Hedge Fund.

The Numerai catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Numerai’s developer surface includes documentation, API reference, getting-started guide, support, signup flow, authentication, CLI, and 25 more developer resources.

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/numerai: open an issue to ask a question, or submit a pull request to add artifacts.
