在 Codex、Claude Code 等编程 Agent 中使用 GPT Image 2

export SEEDROUTER_API_KEY="your-key"

Use the SeedRouter API to generate a gpt-image-2 image for me.

Security: read SEEDROUTER_API_KEY from my local environment. Never ask me to paste it and never expose it in code, prompts, logs, or output.

Goal:
- Use case: [product / social / concept art / UI mockup]
- Subject and style: [subject, composition, lighting, style]
- Size: [auto | 1024x1024 | 1536x1024 | 1024x1536 | WIDTHxHEIGHT]
- Quality: [auto | low | medium | high]
- Number of images: [1-10]
- Acceptance criteria: [e.g. no text in the image, consistent product, clean background]

Request fields this endpoint accepts, and nothing else:
  model (required, "gpt-image-2"), prompt (required, up to 32000 chars),
  n (1-10, default 1), size (default auto; a custom WIDTHxHEIGHT must have
  both sides divisible by 16, neither edge over 3840, total pixels between
  655360 and 8294400, and keep a ratio between
  1:3 and 3:1), quality (auto|low|medium|high, default auto),
  background (auto|opaque|transparent, default auto; transparent requires
  output_format png), output_format (png|jpeg, default png),
  output_compression (0-100, default 100, jpeg only),
  moderation (auto|low, default auto), user (your own identifier).
For editing use /v1/images/generations with images: [{image_url: "https://..."}]
(up to 16) and optional mask: {image_url: "https://..."}. Mask requires images.
Inputs must be URLs, not base64 or multipart files. stream and partial_images
are not supported because delivery is asynchronous.

Before any paid request, show me the model id, the exact request body and the
estimated cost, then wait for my explicit approval.

After approval:
1. POST https://api.seedrouter.ai/v1/images/generations with the body above and
   an Authorization: Bearer $SEEDROUTER_API_KEY header.
2. Save the task id from the response "id" field. The response is
   {"id": "...", "status": "processing"} — the image is not in it.
3. Poll https://api.seedrouter.ai/v1/tasks/{task_id} with the same header every
   5-10 seconds until status is "completed" or "failed". Do not retry forever;
   if you stop waiting, preserve the task id and report that it is still pending.
   A polling timeout is not a failed task. Never submit a duplicate just to check status.
4. On success, download every URL in output.data[].url, return the local paths,
   the task id, and the parameters used. The response carries no cost field.
5. On failure, keep the task id, explain the reason and what to change, and do
   not retry without my approval. A task that ends failed is not charged.
