Welcome to OpenGptApi: start with a clear API contract

Why OGA begins with model discovery, async tasks, route boundaries and queryable settlement for multi-channel AI image APIs.

OpenGptApi, or OGA, is an independent multi-channel AI API platform. Our goal is not to stack provider routes behind a thin proxy. It is to give developers a public contract they can inspect, verify and trust not to widen silently.

Why we start with image tasks

An image request looks simple, but it carries a model, operation, size, input images, masks, output count, route capabilities, pricing, refunds and result lifetime. Two routes can interpret the same parameter differently.

OGA turns those differences into explicit data:

Pricing is not a constant in a web page

The public model page does not hand-copy a price sheet. It reads GET /api/v1/models and follows the runtime response for available routes, price matrices and refund policies.

That removes a seemingly convenient static value, but prevents a dangerous mismatch: the runtime price changes while the website keeps showing an old one.

Route selection needs hard boundaries

Each OGA API key can use all routes or an explicit allow-list, with additional exclusions. If an allow-list admits no compatible route for the requested model and operation, the platform returns the full business reason without creating a task, freezing balance or charging.

OGA does not silently widen a user’s allow-list to improve success rate. When a route switch happens, its reason should also be retained and visible.

Start with the shortest path

Your first integration has three steps:

  1. inspect models and pricing;
  2. create an asynchronous image task with the API documentation;
  3. poll with the task ID and download the image before the result expires.

OGA is still progressing through capability evidence and production gates. We keep “implemented,” “locally tested” and “ready for production” separate instead of replacing evidence with a vague availability promise.
