# Introduction

> Integrate Nova application scoring into your ATS platform

The Nova Embed API lets ATS platforms score applications against job-specific criteria using AI. Generate screening criteria from job descriptions and get structured assessments with scores, strengths, concerns, and interview recommendations.

## Key concepts

| Concept         | Description                                                                |
| --------------- | -------------------------------------------------------------------------- |
| **Integrator**  | Your organization. Billing happens at the integrator level.                |
| **Tenant**      | One of your customers. Used for data isolation and per-customer metrics.   |
| **Environment** | Sandbox (testing) or Production (live). Separate API keys per environment. |

## How it works

### 1. Job setup (once per job)

Generate screening criteria from the job description. Optionally collect answers to clarification questions to refine the criteria. Nova stores criteria automatically.

### 2. Scoring (per applicant)

Submit applications for async scoring. Pass the job ID, application ID, resume, and job description. Nova loads criteria automatically and delivers results via webhook.

## Base URLs

| Service    | URL                               |
| ---------- | --------------------------------- |
| **API**    | `https://embed.nova.dweet.com/v1` |
| **Portal** | `https://embed.nova.dweet.com`    |

## Environments

Your API key prefix determines the environment:

| API Key     | Environment |
| ----------- | ----------- |
| `sk_test_*` | Sandbox     |
| `sk_live_*` | Production  |

Both environments are billed per score at the same rate.

<Info>
  Sandbox runs the same AI models and processing pipeline as production. Scores you generate in sandbox are representative of production quality.
