Production workflow

Integrate once, switch models by configuration

The hub is built around stable developer primitives: API keys, model slugs, category endpoints, task IDs, status polling, and transparent credit usage.

  1. 1

    Create one API key

    Generate a key from the dashboard and keep it server-side in your application environment.

    API keysDocs
  2. 2

    Choose a route and model slug

    Use the hub to pick a category endpoint and model slug. Switch providers by changing the model value.

    Model marketModel Cost Reference
  3. 3

    Poll or receive completion

    Async jobs return a task ID. Poll status or configure a webhook when the selected model supports it.

Agent-ready docs

Give coding agents the API index

Paste this prompt into Codex, Cursor, Claude, or another coding agent so it can read the API in One docs index and answer route-specific integration questions.

About API in One:
Unified AI API gateway with OpenAI-compatible chat completions and REST async routes for image, video, music, speech, and AI tools. It uses one API key, one balance, transparent model costs, task polling, webhook-aware routes, and model detail pages with request examples.

My question:
Which API route and model slug should I use for my product workflow?

API Hub FAQ

What is the API Hub?

The API Hub is a browsable marketplace for API in One model routes. It groups image, video, audio, LLM, speech, and tool APIs into one integration surface.

Do I need separate API keys for each provider?

No. API in One centralizes authentication and billing so your application can call supported model routes with one API key.

Are endpoints OpenAI-compatible?

Chat completions are OpenAI-compatible. Async media, speech, music, and tool routes use documented REST payloads with task IDs and status polling.

How do I compare model costs?

Model cards show approximate per-call costs. The model cost reference page provides a broader table for image and video routes.

Can production apps use webhooks?

Many async routes support webhooks. Model detail pages and docs show whether the selected route supports webhook callbacks or polling only.
