+# Contributing
+
+Useful contributions:
+
+1. A missing route, rate or billing unit — include the model id, the resolution or token direction, and the source page you checked.
+2. A better estimator (per-tenant quota modelling, cached-input share, retry overhead).
+3. Corrections where this snapshot disagrees with your own invoice, with the task or invoice evidence.
+
+Before opening a pull request:
+
+```bash
+python tools/snapshot.py --from-file your_saved_pricing_page.html   # regenerates data/ and README tables
+python tools/check_links.py
+```

+**Why teams call Wan 2.7 Image (`wan2.7-image`) through APIMart**
+
+- **One key, entire catalog.** The same `https://api.apimart.ai/v1` base URL and `Authorization` header reach Wan 2.7 Image (`wan2.7-image`) and 300+ other image, video and language models — switch the `model` field, not your client.
+- **$1 minimum, pay as you go.** No subscription and no prepaid plan to size up front: top up from $1 and spend it on calls.
+- **The charge comes back in the response.** Every completed task reports the amount billed (`cost` / `credits_cost`); a task marked `failed` is refunded.
+- **Async by design.** Submit, take the `task_id`, poll `GET /v1/tasks/{id}` — batching and retries are ordinary queue work, not a bespoke integration.
+
+<!-- /conv-kit:v1 -->
+
+Wan 2.7 Image is Alibaba's Wan text-to-image model in standard and Pro versions for high-quality images.
+
+## Model id and routes
+
+| Route | `model` value | Billing | Notes |
+| --- | --- | --- | --- |
+| Per-image | `wan2.7-image` | per delivered image, by resolution | see the [model page](https://go.apimart.ai/k-638a85) for the exact tiers |
+
+Endpoint: `POST https://api.apimart.ai/v1/images/generations` (OpenAI-compatible), then poll `GET /v1/tasks/{task_id}`.
+
+## Pricing
+
+<!-- pricing:model:start -->
+| Output | List price | Effective price |
+| --- | --- | --- |
+| default | 0.027 | 0.0216 |
+
+
+<!-- pricing:model:end -->
+
+Prices are a snapshot; the [pricing page](https://go.apimart.ai/k-f2e4f9) and [`data/model.json`](data/model.json) are refreshed by CI, and a completed task reports the exact amount in its `cost` field.
+
+## Request parameters
+
+| Field | Type | Default | Notes |
+| --- | --- | --- | --- |
+| `model` | string | required | the model id shown in the route table above |
+| `prompt` | string | required | what to generate, or what to change when editing |
+| `size` | string | `auto` / `1:1` | aspect ratio, or `auto` where the route supports it |
+| `resolution` | string | `1K` | output resolution tier — cost scales with it |
+| `n` | integer | `1` | number of images per task, where the route allows more than one |
+| `image_urls` | string[] | — | reference images as public HTTP(S) URLs or base64 data URLs |
+| `nsfw_check` | boolean | `false` | runs `omni-moderation-latest` before submitting |
+
+The table lists the fields accepted by the APIMart OpenAI-compatible image endpoint. Check the [model page](https://go.apimart.ai/k-638a85) for anything this model adds on top.
 
 ## Quickstart
 
 ```bash
-curl -X POST https://api.apimart.ai/v1/images/generations \
-  -H 'Authorization: Bearer $APIMART_KEY' \
-  -H 'Content-Type: application/json' \
-  -d '{"model":"gpt-image-2.5-ext","prompt":"cozy reading nook, warm lamp, cinematic","size":"1:1","resolution":"1K","n":1}'
+curl --request POST --url https://api.apimart.ai/v1/images/generations \
+  --header "Authorization: Bearer $APIMART_API_KEY" --header 'Content-Type: application/json' \
+  -d '{"model":"wan2.7-image","prompt":"A bamboo forest at sunrise, slow push-in","size":"1:1","resolution":"1K"}'
 ```
 
-Async: submit → get `task_id` → poll `GET https://api.apimart.ai/v1/tasks/<task_id>` → read `cost` / `credits_cost` from the result. Parameter tables, `version`/`resolution`/`size` options and idempotency headers are documented on the model page reachable from the pricing link above.
+```python
+import os, time, requests
+
+BASE = "https://api.apimart.ai/v1"
+HEADERS = {"Authorization": f"Bearer {os.environ['APIMART_API_KEY']}", "Content-Type": "application/json"}
+
+created = requests.post(f"{BASE}/images/generations", headers=HEADERS, timeout=60, json={
+    "model": "wan2.7-image", "prompt": "A bamboo forest at sunrise, slow push-in",
+}).json()
+task_id = created["data"]["id"]
+
+while True:
+    task = requests.get(f"{BASE}/tasks/{task_id}", headers=HEADERS, timeout=60).json()["data"]
+    if task["status"] in ("completed", "failed"):
+        break
+    time.sleep(5)
+print(task.get("cost"), task["result"]["images"][0]["url"])
+```
+
+Runnable versions: [`examples/`](examples). The task lifecycle is `pending → processing → completed | failed`.

+# Security
+
+- This repository contains no credentials and needs none: the pricing snapshot is read from a public page.
+- Never commit API keys. Keys belong in environment variables (`APIMART_API_KEY`) or a secret manager.
+- Retried requests must reuse an `Idempotency-Key`, otherwise a timeout can bill the same image twice.
+- Report a leaked key or a data error privately to the maintainer instead of opening a public issue.
