API endpoint builder
Create a free API endpoint for your next prototype
Create a free REST endpoint for a prototype or small project, then add schemas, API keys, rate limits, logs, and docs as it grows.
What this workflow solves
Go from idea to a stable HTTP contract without building every backend layer first.
Sometimes you do not need a full backend project; you need one dependable endpoint. NexApi is designed so you can begin with a small route and still have a path toward proper validation, authentication, observability, and OpenAPI documentation.
Start with one endpoint instead of a complete backend architecture.
Use standard HTTP methods and JSON responses.
Add access control and rate limiting when the endpoint becomes public.
Keep request history visible through built-in logs.
How it works
A short path from data model to usable endpoint.
Create a project
Set up a small NexApi project for the endpoint you need.
Choose the method and path
Define a route such as GET /status or POST /leads.
Set the contract
Add request fields, response mapping, auth, and rate-limit rules as needed.
Use the runtime URL
Call the endpoint from your app, script, automation, or test suite.
GET /r/demo/status{
"ok": true,
"service": "demo-api",
"version": "1"
}A tiny status endpoint
Even a small endpoint can have a stable contract and observable request history.
Built into NexApi
The API operations layer is already there.
Start small, then add the controls normally scattered across backend code, gateway config, webhook workers, and observability tools.
Visual endpoint builder
Configure methods, paths, request schemas, and response mappings from one interface.
API keys and access
Add API-key based access rules and keep public endpoints under control.
Rate limits and caching
Apply endpoint-level runtime controls without rebuilding the surrounding backend.
Webhooks and connectors
Connect REST APIs with Google Sheets, Slack, Discord, webhooks, Postgres, MySQL, and external REST APIs.
OpenAPI output
Keep the API contract consumable by documentation and developer tooling.
Logs and analytics
Inspect requests and usage from the same dashboard used to configure the API.
Good fit for
Teams that want to ship the API contract first.
Frequently asked
Can I start with just one endpoint?
Yes. NexApi does not require you to model a large backend before you can publish a useful route.
Can I add more endpoints later?
Yes. APIs can grow with additional routes, schemas, data sources, and access rules.
Is NexApi limited to GET requests?
No. The builder supports the common REST methods, including write operations where your data configuration allows them.
Build it in NexApi
Turn this use case into a working endpoint.
Start with the contract you need now, then add keys, connectors, webhooks, analytics, and OpenAPI as the project grows.
