You have an idea for an API. Maybe it's a SaaS backend, a microservice, or an internal tool. The idea is clear in your head, but turning it into a proper OpenAPI spec — the kind that actually ships with your project — takes hours. You have to think through every endpoint, every request body, every response schema, every status code.
What if you could skip that grunt work?
8sprint is an AI documentation platform that takes your project idea and produces a complete, production-ready architecture package — including an OpenAPI 3.1 spec, Prisma schema, Mermaid diagrams, and over 15 markdown docs — in under 3 minutes.
Here's how it works.
Step 1: Describe Your Project in Plain English
Start at 8sprint.com and describe your project. You don't need formal language, bullet points, or an outline. Just write what you'd tell a senior engineer in a 5-minute Slack message.
Here's an example prompt:
"Build a project management API with users, teams, projects, and tasks. Users can belong to multiple teams. Teams own projects. Projects contain tasks with status (todo, in_progress, done), due dates, and assignees. I need JWT auth, pagination on list endpoints, and role-based access for team admins vs members."
That's it. Hit generate.
Step 2: 8 Specialized AI Agents Get to Work
8sprint routes your description through 8 specialized agents — each responsible for a different piece of your architecture:
- Requirements Extractor — parses your description and builds a structured model of resources, relationships, and constraints
- Tech Stack Validator — identifies your target stack and validates compatibility of the proposed architecture
- Architecture Designer — maps out resource relationships, endpoint surface, and system boundaries
- Schema & API Generator — writes the full OpenAPI 3.1 spec with schemas, paths, and security definitions, and produces the Prisma schema
- Documentation Writer — generates README, API guide, data dictionary, and 12+ supporting docs
- Quality Assurance — validates consistency and correctness across all outputs
- GitHub Repository Creator — packages all artifacts and pushes them to a new GitHub repository
- UX/UI Design Advisor — identifies frontend considerations and surface-area recommendations
Step 3: Review Your Generated OpenAPI Spec
Within 3 minutes, 8sprint delivers a complete OpenAPI 3.1 spec. Here's a condensed excerpt from the project management example above:
openapi: 3.1.0
info:
title: Project Management API
version: 1.0.0
description: Team-based project and task management with role-based access control
servers:
- url: https://api.yourapp.com/v1
security:
- bearerAuth: []
components:
securitySchemes:
bearerAuth:
type: http
scheme: bearer
bearerFormat: JWT
schemas:
Task:
type: object
required: [id, title, status, projectId]
properties:
id:
type: string
format: uuid
title:
type: string
maxLength: 255
status:
type: string
enum: [todo, in_progress, done]
dueDate:
type: [string, "null"]
format: date-time
assigneeId:
type: [string, "null"]
format: uuid
projectId:
type: string
format: uuid
createdAt:
type: string
format: date-time
paths:
/tasks:
get:
summary: List tasks
parameters:
- name: projectId
in: query
required: true
schema:
type: string
format: uuid
- name: status
in: query
schema:
type: string
enum: [todo, in_progress, done]
- name: page
in: query
schema:
type: integer
default: 1
- name: limit
in: query
schema:
type: integer
default: 20
maximum: 100
responses:
'200':
description: Paginated task list
content:
application/json:
schema:
type: object
properties:
data:
type: array
items:
$ref: '#/components/schemas/Task'
meta:
type: object
properties:
total:
type: integer
page:
type: integer
limit:
type: integer
This is valid OpenAPI 3.1 — note the type: [string, "null"] union syntax for nullable fields, which replaced the nullable: true keyword from OpenAPI 3.0. You can load this straight into Swagger UI, Redoc, or Stoplight — or feed it directly into code generators.
Step 4: Get the Full Architecture Package
The OpenAPI spec is just one artifact. 8sprint also delivers:
-
Prisma schema — with correct
@relationannotations, cascade rules, and indexed foreign keys - Mermaid ER diagram — showing entity relationships for your README
- Mermaid sequence diagrams — for key flows like auth, task creation, and role checks
- 15+ markdown docs — including a data dictionary, API guide, environment variables reference, error catalog, and deployment checklist
Step 5: Push to GitHub in One Click
The GitHub Repository Creator agent packages all artifacts — spec, schema, diagrams, and docs — and pushes them to a new GitHub repository. Your project starts with documentation already in place, not as an afterthought.
Why This Matters for AI API Documentation
The traditional workflow looks like this: build → document → realize the docs are already stale → abandon. The 8sprint workflow flips it: describe → document → build.
Starting with a solid OpenAPI spec means your team can:
- Generate mock servers immediately with tools like Prism
- Start frontend or client development before the backend is built
- Run contract tests from day one
- Onboard new engineers with accurate, structured reference material
