# Avviament svelt

Efectues tia emprima generaziun en paucs minuts. Tut ils 1 496 models acceptan il medem gener de dumonda e returnan il medem object da dumonda, per maletgs, video ed audio: emprenda quai ina giada qua.

> [!NOTE]
> URL da basa `https://api.doitong.ru/v1`. Mintga clamada trametta `Authorization: Bearer <your key>`, e la medema clav funcziuna per l'API HTTP e per il server MCP.

## 1. Obtegna ina clav API

Crees ina clav a [https://doitong.com/developers/dashboard#keys](https://doitong.com/developers/dashboard#keys) e tegnla en ina variabla d'ambient: ella vegn mussada mo ina giada. Mintga clav po avair ses agen budget, uschia che ti la pos dar ad in agent senza ristgar l'entir conto. `GET /account` returna tes saldo API.

```bash
export DOITONG_API_KEY="doitong_..."

curl "https://api.doitong.ru/v1/account" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```
```javascript
const res = await fetch("https://api.doitong.ru/v1/account", {
  headers: { Authorization: `Bearer ${process.env.DOITONG_API_KEY}` },
});

console.log(await res.json());
```
```python
import os
import requests

r = requests.get(
    "https://api.doitong.ru/v1/account",
    headers={"Authorization": f"Bearer {os.environ['DOITONG_API_KEY']}"},
)
print(r.json())
```

Las execuziuns vegnan pajadas dal **saldo API** da tes conto en credits API: 1 000 credits API = $1, e mintga model custa exactamain il pretsch da ses producent. Fa ina chargiada a [https://doitong.ru/developers/dashboard#balance](https://doitong.ru/developers/dashboard#balance).

## 2. Dumonda in pretsch, lura exequies

`POST /quote/{model_id}` prenda il JSON d'input e returna il pretsch exact. I na dovra nagina clav e na custa nagut. La medema input custa exact quai: la quotaziun è la chargiada. (In model chargià tenor utilisaziun è l'excepziun: sia quotaziun è il maximum che l'execuziun po custar, e la part betg utilisada vegn restituida suenter l'execuziun.)

```bash
curl -X POST "https://api.doitong.ru/v1/quote/kling-video/v3/pro/image-to-video" \
  -H "Content-Type: application/json" \
  -d '{"image": "https://example.com/fox.jpg", "duration": 5, "generate_audio": true}'
```
```javascript
const res = await fetch("https://api.doitong.ru/v1/quote/kling-video/v3/pro/image-to-video", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ image: "https://example.com/fox.jpg", duration: 5, generate_audio: true }),
});

const quote = await res.json();
console.log(quote.credits, quote.usd); // 840 "0.84"
```
```python
import requests

r = requests.post(
    "https://api.doitong.ru/v1/quote/kling-video/v3/pro/image-to-video",
    json={"image": "https://example.com/fox.jpg", "duration": 5, "generate_audio": True},
)
print(r.json()["credits"], r.json()["usd"])  # 840 0.84
```

```json 200 OK · quotaziun
{
  "object": "quote",
  "model": "kling-video/v3/pro/image-to-video",
  "credits": 840,
  "usd": "0.84",
  "unit": "second",
  "quantity": 5,
  "unit_credits": 168,
  "mode": "exact",
  "breakdown": "5 s × 168 API credits"
}
```

Lura trametta il medem coss a `POST /run/{model_id}`. Aggiunta `?wait=20` per tegnair la connexiun averta durant maximalmain 20 secundas: in model svelt returna il resultat terminà en ina unica communicaziun. Trametta in header `Idempotency-Key` per che ina repetiziun na lantschia (ni chargia) mai duas giadas.

```bash
curl -X POST "https://api.doitong.ru/v1/run/flux/schnell?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: lighthouse-001" \
  -d '{"prompt": "A lighthouse on a rocky coast at dusk, warm light in the window"}'
```
```javascript
const res = await fetch("https://api.doitong.ru/v1/run/flux/schnell?wait=20", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.DOITONG_API_KEY}`,
    "Content-Type": "application/json",
    "Idempotency-Key": "lighthouse-001",
  },
  body: JSON.stringify({ prompt: "A lighthouse on a rocky coast at dusk, warm light in the window" }),
});

const request = await res.json();
console.log(request.status, request.outputs[0]?.url);
```
```python
import os
import requests

r = requests.post(
    "https://api.doitong.ru/v1/run/flux/schnell",
    params={"wait": 20},
    headers={
        "Authorization": f"Bearer {os.environ['DOITONG_API_KEY']}",
        "Idempotency-Key": "lighthouse-001",
    },
    json={"prompt": "A lighthouse on a rocky coast at dusk, warm light in the window"},
)
request = r.json()
print(request["status"], request["outputs"][0]["url"] if request["outputs"] else None)
```

La resposta è in object da dumonda:

```json 200 OK · dumonda
{
  "id": "req_8k2m4q7x1z9c3v5b6n0p2r4t",
  "object": "request",
  "model": "flux/schnell",
  "status": "succeeded",
  "cost": { "credits": 3, "usd": "0.003", "charged": 3, "refunded": 0 },
  "outputs": [
    { "type": "image", "url": "https://content.doitong.com/dev-api/2026/10/20/req_8k2m4q7x1z9c3v5b6n0p2r4t/0-output.jpeg",
      "content_type": "image/jpeg", "width": 1024, "height": 768, "stored": true }
  ],
  "error": null
}
```

## 3. Suanda il status

Sche il model lavura anc cura che l'attesa finescha, survegns `202 Accepted` cun l'`id` da la dumonda e ses `status` actual. Mintga dumonda passa tras il medem ciclus da vita:

Ciclus da vita da la dumonda: `queued` → `running` → `succeeded` | `failed` | `canceled` (final; las dumondas falladas e annulladas vegnan restituìdas).

Legia danovamain la dumonda cun ses id. `?wait=20` funcziuna era qua, uschia ch'in simpel ciclus basta:

```bash
curl "https://api.doitong.ru/v1/requests/req_8k2m4q7x1z9c3v5b6n0p2r4t?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```
```javascript
const headers = { Authorization: `Bearer ${process.env.DOITONG_API_KEY}` };
let request = await (await fetch("https://api.doitong.ru/v1/requests/req_8k2m4q7x1z9c3v5b6n0p2r4t?wait=20", { headers })).json();

while (request.status === "queued" || request.status === "running") {
  const res = await fetch(`https://api.doitong.ru/v1/requests/${request.id}?wait=20`, { headers });
  request = await res.json();
}

console.log(request.status, request.outputs[0]?.url);
```
```python
import os
import requests

headers = {"Authorization": f"Bearer {os.environ['DOITONG_API_KEY']}"}
request = {"id": "req_8k2m4q7x1z9c3v5b6n0p2r4t", "status": "queued"}

while request["status"] in ("queued", "running"):
    request = requests.get(
        f"https://api.doitong.ru/v1/requests/{request['id']}",
        params={"wait": 20},
        headers=headers,
    ).json()

print(request["status"], request["outputs"][0]["url"] if request["outputs"] else None)
```

Cura che `status` è `succeeded`, cuntegna `outputs[].url` ils links a las datotecas en nossa memorisaziun. Sche la dumonda è `failed` u `canceled`, vegnan ses credits API restituids automaticamain e `error` declera il motiv. Cancelescha tut quai che stat anc en `queued` u `running`:

```bash
curl -X POST "https://api.doitong.ru/v1/requests/req_8k2m4q7x1z9c3v5b6n0p2r4t/cancel" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

Per lungs jobs da video pos ti sursiglir il polling e passar in `webhook_url` empè da quai (vesair [Webhooks](https://doitong.com/developers/docs/webhooks)).

## 4. Datotecas

Passa mintga URL public sco input, u dumonda `POST /files` per ina URL d'upload, fa `PUT` da la datoteca là e utilisescha il `file_url` returnà (vesair [Datotecas](https://doitong.com/developers/docs/files)). Ina dumonda reussida enumerescha ses resultats en `outputs[]` cun il tip, il tip da cuntegna e, sch'èn enconuschentas, las dimensiuns e la durada.

```bash
curl -X POST "https://api.doitong.ru/v1/files" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"filename": "fox.jpg", "content_type": "image/jpeg", "size": 482113}'
```

> [!TIP]
> **Datotecas tegnidas per adina, u 7 dis gratuitamain: ti decidas.** Las datotecas d'output vegnan copiadas en nossa memorisaziun avant che ina dumonda reusseschia. Standard restan ellas fin che ti las stizzas (100 credits API per GB e mais); deactivescha "Conservar las datotecas per adina" en il dashboard, u passa `?storage=temporary`, per las tegnair 7 dis gratuitamain (vesair [Datotecas](https://doitong.com/developers/docs/files#storage)).

## Errurs

Mintga model fallescha en la medema moda: in envelop cun in `type`, in `code` exact, il `param` problematica e mintga problem en `details`, uschia che in agent po curreger la dumonda senza leger prosa. Ina dumonda invalida na vegn mai chargiada.

```json 422 Unprocessable Entity
{
  "error": {
    "type": "invalid_request",
    "code": "invalid_input",
    "message": "duration must be one of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15.",
    "param": "duration",
    "details": [ { "param": "duration", "message": "duration must be one of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15." } ],
    "request_id": null,
    "doc_url": "https://doitong.com/developers/docs/errors#invalid_input"
  }
}
```

Mintga tip e code èn enumerads en [Errurs](https://doitong.com/developers/docs/errors).

## Pretschs

Ils pretschs èn en USD e credits API e vegnan mussads sin mintga pagina da model avant l'execuziun. Mintga dumonda cuntegna `cost` cun `credits`, `usd`, `charged` e `refunded`. Ina execuziun vegn chargiada cura ch'ella vegn acceptada; las dumondas `failed` e `canceled` vegnan restituids automaticamain. Tscherts models vegnan pretschads exactamain tenor l'input, tscherts tenor la lunghezza u grondezza da las datotecas che ti tramettas, ed auters chargian in *pretsch stimà per execuziun*: en mintga cas è la quotaziun quai che ti pajas. Pauc models (models da linguas e da visiun, vusch, utensils da temp da processament) vegnan *chargiads tenor utilisaziun*: la quotaziun è il maximum che l'execuziun po custar, e la part che l'execuziun n'ha betg utilisà vegn restituida automaticamain. Vesair [Pretschs](https://doitong.com/developers/docs/pricing).

## MCP ed agents d'IA

Colleges mintga client MCP a `https://api.doitong.ru/v1/mcp` cun la medema clav Bearer. Tes agent po tschertgar en il catalog, dumandar pretschs ed exequir models, e leger mintga pagina da documentaziun sco Markdown.

```bash Claude Code
claude mcp add --transport http doitong-models https://api.doitong.ru/v1/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"
```
