# Sensenova U1 Infographic API

> Für Infografiken optimiertes Text-zu-Bild-Modell mit neun Seitenverhältnissen und optionalem Reasoning vor der Erzeugung

Erzeugt Infografikbilder aus detaillierten Prompts, die Layout, Abschnitte, Farbpalette, Typografie und Daten beschreiben. Das Seitenverhältnis ist eine von neun Voreinstellungen, standardmäßig 16:9. Sampling-Steuerungen umfassen `num_inference_steps` (10 bis 100), `guidance_scale` (1 bis 10) und `timestep_shift`. `use_thinking` führt zuerst einen Reasoning-Durchlauf aus und gibt dessen Trace zurück.

- Model id: `sensenova-u1-infographic`
- Made by: SenseTime
- Category: Text to Image
- Output: image
- Price: from $0.05 / image (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.com/v1/run/sensenova-u1-infographic`
- Quote: `POST https://api.doitong.com/v1/quote/sensenova-u1-infographic`
- Docs page: https://doitong.com/de/developers/models/sensenova-u1-infographic

## Pricing

Price: **from $0.05 / image** (the lowest tier; the quote prices your exact input). Billed per generated image.

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `use_thinking` = true: $0.06 (60 API credits) / image

The full example input below costs $0.05 = 50 API credits (1 image × 50 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/sensenova-u1-infographic` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Beschreibung der zu generierenden Infografik; für beste Ergebnisse sollten konkrete Typografie, zu visualisierende Daten, Abschnittsaufbau, Layout und Farbpalette angegeben werden. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `1:1`, `16:9`, `9:16`, `3:2`, `2:3`, `4:3`, `3:4`, `1:2`, `2:1` | Bildproportionen, standardmäßig 16:9, zur Kompatibilität mit den meisten als Poster oder Präsentation vorgesehenen Infografikdesigns. Unterstützt werden nur Seitenverhältnisse, die den während des Trainings verwendeten Auflösungsstufen entsprechen. |
| `num_inference_steps` |  | integer | no | `50` | 10 – 100 | Anzahl der Schritte für die Flow-Matching-Entrauschung. |
| `guidance_scale` |  | number | no | `4` | 1 – 10 | Skalierung für classifier-free guidance; eine Erhöhung bewirkt eine stärkere Orientierung der Ausgabe am Prompt. |
| `timestep_shift` |  | number | no | `3` | 1 – 8 | Die Bevorzugung früherer Zeitschritte beim Flow-Matching-Sampling wird durch Erhöhen dieses Timestep-Shift-Faktors verstärkt. |
| `use_thinking` |  | boolean | no | `false` |  | Steuert, ob chain-of-thought vor der Bildgenerierung ausgeführt wird; bei True aktiviert. |
| `seed` |  | integer \| null | no |  |  | Seed für reproduzierbare Bilder: Ein identischer Prompt und Seed erzeugen bei unveränderter Modellversion ein identisches Bild. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Aktivierung der Sicherheitsprüfung; true aktiviert die Prüfung. |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | Dateiformat des resultierenden Bilds. |

## Example input

Required parameters only:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/sensenova-u1-infographic?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/sensenova-u1-infographic?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/sensenova-u1-infographic", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "sensenova-u1-infographic",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
