Endpoints are the foundation of Endprompt. They provide stable API URLs that your applications call, while giving you complete flexibility to change the underlying prompts and models.

​
What is an Endpoint?

An endpoint is a stable API contract that defines:
  • URL Path — Where your API lives (e.g., /api/v1/summarize)
  • Input Schema — What data your API accepts
  • Output Schema — What data your API returns
  • Default Prompt — Which prompt handles requests

​
Why Endpoints Matter

Stable Integration

Your application code calls the same URL forever. Change prompts without deployments.

Schema Validation

Invalid requests are rejected before hitting the LLM, saving costs and preventing errors.

Multiple Prompts

Attach multiple prompts to one endpoint. A/B test, version, and rollback independently.

Auto-Generated Docs

Every endpoint gets OpenAPI documentation with code samples automatically.

Endpoint Properties

​
Endpoint Lifecycle

1

Create

Define the endpoint with a name, path, and description.
2

Configure Schema

Add input fields with types and validation rules. Optionally define output schema.
3

Attach Prompts

Create one or more prompts with different models or approaches.
4

Test

Use the built-in test runner to validate your prompts work correctly.
5

Set Default

Promote a prompt to Live status and set it as the endpoint default.
6

Deploy

Your endpoint is ready! Call it from your application.

​
Organizing Endpoints

​
Categories

Group related endpoints with categories:
  • Content — Summarization, rewriting, translation
  • Analysis — Sentiment, classification, extraction
  • Generation — Creative writing, code generation
  • Conversation — Chatbots, Q&A systems
Create categories that match your product domains. You can filter and search by category in the endpoints list.

​
Naming Conventions

We recommend these patterns:

​
Viewing Endpoints

The Endpoints page shows all your endpoints in a list or grid view:
  • Search — Find endpoints by name or path
  • Filter by Category — Show only specific categories
  • Sort — By name, creation date, or recent activity
  • Quick Stats — See request counts and success rates at a glance
