# IP Adapter Face ID API

> Genereert afbeeldingen die overeenkomen met een gezicht uit één foto of een zip met foto's, op SD 1.5- of SDXL-bases

Personaliseert generatie voor een gezicht via `face_image_url`, of via een zip met meerdere gezichten in `face_images_data_url`, waarvan de embeddings worden gemiddeld. `model_type` kiest uit SD 1.5- en SDXL-varianten en de basischeckpoints kunnen worden gewijzigd met repo-parameters. `width` en `height` lopen van 512 tot 1024 en `num_inference_steps` tot 200.

- Output: image
- Estimated price per run: $0.015 / image (cheapest run $0.06 (60 API credits))
- Run: `POST https://api.doitong.com/v1/run/ip-adapter-face-id`
- Quote: `POST https://api.doitong.com/v1/quote/ip-adapter-face-id`
- Docs page: https://doitong.com/nl/developers/models/ip-adapter-face-id

## Pricing

Price: **$0.015 / image**. Estimated from the typical cost of one run, per output (`num_samples`). The quote is exactly what the run charges.

The full example input below costs $0.06 = 60 API credits (4 images × 15 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/ip-adapter-face-id` 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 |
|---|---|---|---|---|---|---|
| `model_type` |  | enum (string) | no | `1_5-v1` | `1_5-v1`, `1_5-v1-plus`, `1_5-v2-plus`, `SDXL-v1`, `SDXL-v2-plus`, `1_5-auraface-v1` | Modelselectie, waarbij 1_5 zowel de standaard als de aanbevolen keuze is voor de meeste toepassingen. |
| `prompt` |  | string | yes |  |  | Beschrijf de afbeelding die je wilt laten genereren zo gedetailleerd mogelijk voor de beste resultaten. |
| `face_image_url` |  | string (image URL) \| null | no |  |  | Referentieafbeelding voor gezichtsovereenkomst, die wordt geschaald en bijgesneden naar 640x640 wanneer de afmetingen daarvan afwijken. |
| `face_images_data_url` |  | string \| null | no |  |  | URL van het zip-archief met gezichtsafbeeldingen, gebruikt om een nauwkeuriger face ID te maken door embeddings uit de gearchiveerde afbeeldingen te middelen. |
| `negative_prompt` |  | string | no | `blurry, low resolution, bad, ugly, low quality, pixelated, interpolated, compression artifacts, noisey, grainy` |  | Negatieve prompt met ongewenste afbeeldingsdetails. Hiermee kunnen kleuren, objecten, landschappen of fijnere kenmerken en kwaliteiten, zoals een snor, vervaging of lage resolutie, worden uitgesloten. |
| `seed` |  | integer \| null | no |  |  | Seed voor het reproduceren van afbeeldingen in Stable Diffusion. Een afbeelding kan bij elke run exact worden gereproduceerd door de modelversie, prompt en seed ongewijzigd te laten. |
| `guidance_scale` |  | number | no | `7.5` | 0 – 16 | Sterkte waarmee de prompt wordt gevolgd bij beeldselectie, uitgedrukt als CFG (Classifier Free Guidance). |
| `num_inference_steps` |  | integer | no | `50` | 1 – 200 | Aantal inferentiestappen voor afbeeldingsgeneratie; grotere aantallen leveren betere beeldkwaliteit op ten koste van een langere generatietijd. |
| `num_samples` |  | integer | no | `4` | 1 – 4 | Aantal monsters voor face ID, standaard ingesteld op 4. Een hoger aantal verbetert de afbeeldingskwaliteit maar verlengt de generatietijd. |
| `width` |  | integer | no | `512` | 512 – 1,024 | Breedte van de resulterende afbeelding. |
| `height` |  | integer | no | `512` | 512 – 1,024 | Hoogte van de resulterende afbeelding. |
| `face_id_det_size` |  | integer | no | `640` | 64 – 640 | Stel de grootte van het gezichtsdetectiemodel in en verklein deze als het model geen gezicht in je afbeelding kan vinden. Een grotere instelling zorgt voor nauwkeurigere detectie, maar werkt ook langzamer en mist een gezicht eerder volledig. |
| `base_1_5_model_repo` |  | string | no | `SG161222/Realistic_Vision_V4.0_noVAE` |  | URL van het basismodel 1.5; standaard ingesteld op `SG161222/Realistic_Vision_V4.0_noVAE`. |
| `base_sdxl_model_repo` |  | string | no | `SG161222/RealVisXL_V3.0` |  | URL van het basismodel SDXL; standaard ingesteld op `SG161222/RealVisXL_V3.0`. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Screening kan worden versoepeld door false in te stellen, mits de aanroeper is geautoriseerd. |

File parameters (`face_image_url`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## 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/ip-adapter-face-id?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/ip-adapter-face-id?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/ip-adapter-face-id", 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": "ip-adapter-face-id",
      "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.
