SKILLS

Install the GPT Image 2 skill for app development

Load the model docs, schemas, pricing notes, and setup steps into your coding workspace.

# Install the model skill for app development workflows
npx skills add runapi-ai/gpt-image-2 -g

Installs docs, schemas, pricing context, and setup notes into your developer workspace.

Or use this setup request in your coding tool:

Install the GPT Image 2 skill for this app:

1. Add runapi-ai/gpt-image-2 with the skills installer.
2. Load SKILL.md in this workspace.
3. Use its docs, schemas, pricing notes, and setup steps when adding model features.
4. Confirm the install path when done.

HOW IT WORKS

From model skill to first result in four steps

Choose a model

Browse the model catalog and pick the model and variant that match your output type, quality bar, and latency target. Each variant page shows its model ID, pricing, and parameter constraints so you can compare before committing.

Configure

Set your RunAPI API key as an environment variable and install the model skill in your coding workspace. The skill loads docs, typed schemas, pricing notes, and setup steps so your agent has the right context from the start.

Call

Use the skill instructions to add the model feature inside your application. Send a POST request with your prompt, model ID, and parameters. RunAPI routes the request, manages the async lifecycle, and returns structured JSON.

Receive

Poll by task ID for completion, stream results end-to-end when supported, or configure a webhook callback URL to receive results automatically. The CLI provides a built-in wait command, and the SDKs offer both polling and callback patterns.

CONTEXT

What is the GPT Image 2 API?

GPT Image 2 is OpenAI's newest image model, notable for near-perfect multilingual text rendering. Through RunAPI, both text-to-image and image editing endpoints share one key.

WHY RUNAPI

Why route the GPT Image 2 API through RunAPI

One auth, every provider

A single RunAPI API key unlocks the whole model catalog across all providers. No separate accounts to create, no API keys to rotate per integration, and no credential management overhead. Add a new model to your app by changing one parameter.

Unified pricing & billing

Per-call pricing in USD, billed monthly into a single invoice. No subscription tiers, no minimum spend, and failed generations are never charged. The pricing page and check_pricing API show exact costs before you commit to a model.

Schema-first SDK

Typed schemas, parameter constraints, and setup notes are packaged in the model skill so your implementation starts from the right contract. The skill loads into Claude Code, Codex, Gemini CLI, Cursor, and VS Code — your agent knows the correct request shape before you write a line of code.
