MagicX

MagicX Inc. builds software that lets people take actions instantly from any text box. Its flagship developer product, AI Autocomplete, is a drop-in SDK and HTTP API that turns a blank input into instant intent — guiding users on what to type with roughly 200ms suggestions, delivered as native SDKs for React, Angular, Vanilla JS and Swift or a framework-agnostic HTTP API. Auth uses public, secret, and short-lived access-token keys, and pricing is usage-based per prediction with a SOC 2 enterprise tier. MagicX also ships Hero Assistant, a consumer AI assistant. The company is backed by Forerunner Ventures.

MagicX publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Autocomplete, Developer Tools, and SDK.

MagicX’s developer surface includes documentation, API reference, getting-started guide, pricing, authentication, and 16 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/magicx: open an issue to ask a question, or submit a pull request to add artifacts.
