micro1

micro1 is an AI-native talent and human-data company. Its AI recruiter, Zara, runs conversational technical interviews at scale — generating role-specific questions from the skills you want tested, branching in real time, adding an optional coding exercise, and returning a structured report with per-skill AI ratings, CEFR-style soft-skill scores, a proctoring integrity score, transcripts and session recordings. The company also operates an expert-human-data business (Realm reinforcement- learning environments, Cortex agent evaluations, and robotics data collection) that supplies training and evaluation data to frontier AI labs. The micro1 Public API exposes the AI-interview platform: create standard or custom-question interviews, invite candidates, list jobs and job applicants, retrieve completed reports and recordings, and register webhooks so an ATS is notified in real time when interviews start, reports are generated, recordings finish processing, or resume scores land.

micro1 publishes 6 APIs on the APIs.io network, including Interview API, Interview Reports API, Invite Candidate API, and 3 more. Tagged areas include Company, Recruiting, Hiring, AI Interviews, and Talent Assessment.

The micro1 catalog on APIs.io includes 1 event-driven AsyncAPI specification.

micro1’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, signup flow, authentication, and 20 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

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/micro1: open an issue to ask a question, or submit a pull request to add artifacts.
