MerQube

MerQube is an index technology company that designs, calculates and administers rules-based investment strategies and custom indices for banks, asset managers and ETF issuers. Its cloud-native platform is API-first: the public MerQube API (api.merqube.com) exposes an IndexAPI for creating, editing, running and deleting index manifests, target portfolios, index documents and identifiers, and a SecAPI for retrieving security metrics, index levels, portfolios and statistics across equities, futures, options and MerQube indices. The company publishes a link-resolved OpenAPI 3.1 description from the API host itself, a browsable rendering at merqube.com/api, a Stoplight documentation portal, and a first-party Apache-2.0 Python client library on PyPI and GitHub.

MerQube publishes 9 APIs on the APIs.io network, including Helper API, Identifier API, and 7 more. Tagged areas include Company, Financial-Services, Index Data, Market Data, and Capital Markets.

MerQube’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, FAQ, and 26 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data 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/. 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/merqube: open an issue to ask a question, or submit a pull request to add artifacts.
