## Use FLUX.1 Kontext Pro in your assistant

Paste this prompt into Claude Code, Codex, Cursor or any agent. It reads the guide and helps you connect.

```
Read https://flymy.ai/skill.md and https://flymy.ai/mcp/models/flux-kontext-pro.md. Help me connect the FlyMy.AI MCP to this assistant, then run FLUX.1 Kontext Pro (flymyai/flux-kontext-pro) for this task: Replace the background of the photo I attach with a rainy neon street at night using FLUX.1 Kontext Pro.

## What FLUX.1 Kontext Pro does

Send an input_image and a prompt that says what to change. Kontext Pro is strong at targeted edits that leave everything else in place; for the hardest edits and text, use Kontext Max. Choose an aspect_ratio (1:1, 16:9, 9:16, 1:2, 7:3 or 3:7), a seed, safety_tolerance and prompt_upsampling.

## FLUX.1 Kontext Pro inputs

Every input of `flymyai/flux-kontext-pro` as its live schema lists them. Returns `output` (file).

## Call FLUX.1 Kontext Pro from code

The same model, from an agent or from your own code. Keys stay in your FlyMy.AI account.

### From an agent, through the MCP

The agent calls `get_model_schema`, then `run_model` with:

```
{
  "endpoint_id": "flymyai/flux-kontext-pro",
  "input": {
    "prompt": "Replace the background with a marble table by a sunny window",
    "aspect_ratio": "1:1",
    "seed": "42",
    "prompt_upsampling": "true",
    "safety_tolerance": "2",
    "input_image": "https://example.com/photo.jpg"
  }
}
```

### From your code, over HTTP

Form fields, not JSON; files go as uploads or public URLs. The answer is a `prediction_id`; read the result at `https://api.flymy.ai/api/v1/flymyai/flux-kontext-pro/predict/async/result/?request_id=<prediction_id>`.

```
curl -X POST https://api.flymy.ai/api/v1/flymyai/flux-kontext-pro/predict/async/ \
  -H "X-API-KEY: $FLYMYAI_API_KEY" \
  -F 'prompt=Replace the background with a marble table by a sunny window' \
  -F 'aspect_ratio=1:1' \
  -F 'seed=42' \
  -F 'prompt_upsampling=true' \
  -F 'safety_tolerance=2' \
  -F "input_image=@photo.jpg"
```
