**Cost**: 5 credits per successful conversion (failures do not consume credit).

SVG Converter Create supports two input modes:

1. **JSON URL mode**: send `application/json` with the existing URL field.
2. **Direct upload mode**: send `multipart/form-data` with a local image file in the `image` field. The compatible field name `file` is also accepted for the primary image. Codia checks credits before reading and uploading the file, so insufficient-credit requests return `402` without uploading anything.

Direct upload example:

```bash
curl 'https://openapi.codia.ai/v2/open/svg_converter/create' \
  -H 'Authorization: Bearer {codia_api_key}' \
  -F 'image=@./logo.png' \
  -F 'file_name=logo.png'
```

Submit a raster image (PNG / JPG / GIF / WebP) for vectorization to **SVG**. The conversion runs asynchronously — call this endpoint to enqueue, then poll `GET /v2/open/svg_converter/result/{record_id}` with the returned `record_id` until the SVG is ready.

## What this API is for

Auto-trace a bitmap into clean vector paths so it scales to any resolution without aliasing. Designed for logos, icons, illustrations, and other flat-art assets — not for photographic content (which doesn't vectorize well by nature).

Typical use cases: rebuilding a missing logo source from a PNG export; preparing assets for print or large-format displays; reducing file size for icon sets; preserving crisp edges in design systems.

## Lifecycle

This is an async, polling-based task (no webhook):

1. **Submit** here. Returns immediately with `data.record_id` (UUID).
2. **Poll** `GET /v2/open/svg_converter/result/{record_id}` with that `record_id`. The result's integer `svg_convert_status` transitions `1` (doing) → `2` (complete, with `svg_url`) or `3` (failed).
3. **Download** the `.svg` from `svg_url` once complete. URLs are pre-signed; fetch promptly and self-host for long-term use.

Typical end-to-end is **5–30 seconds** depending on detail level. Poll every 1–3 seconds.

## Request

| Field | Required | Notes |
|---|---|---|
| `image_url` | yes | Public URL of the raster image (PNG / JPG / GIF / WebP). Must be reachable from Codia's network. The legacy name `pic_url` is still accepted. |
| `file_name` | no | Original file name, used only for record-keeping in your dashboard. |

## Plan limits

Maximum image dimensions and file size depend on your subscription plan. Use `GET /v2/open/svg_converter/limit` at runtime to read your live limits — values below are indicative defaults:

| Plan | Max dimensions | Max file size |
|---|---|---|
| Free | 512×512 | 512 KB |
| Starter | 1024×1024 | 2 MB |
| Pro | 2048×2048 | 4 MB |

## Response

Standard envelope. On 200, `data.record_id` is the UUID you'll need to poll for the result. **Nothing else is returned at this stage** — the SVG itself comes from the `get` endpoint.

## Billing

5 credits per **successful** conversion (deducted when the task completes, not at submission — failed jobs don't consume credit). Uses the unified Codia Open API balance.

## Errors

- `400` — missing `image_url`, unsupported MIME, or input exceeds your plan's dimensions / file size limits.
- `401` / `403` — auth issues.
- `402` — credits exhausted.
- `429` — rate limit. Back off.
- `500` — internal error; safe to retry.

可选，由用户自定义的幂等键（最多 255 个字符）。设置后，成功（2xx）的响应会缓存 7 天。使用相同的键 + 相同的请求体重试，会返回缓存的响应（不额外扣除积分）；使用相同的键但不同的请求体重试，则返回 409。用于确保 POST 请求在网络故障时可以安全重试。对于 multipart/form-data 上传，请求会按表单字段和文件内容进行比较，因此即使客户端生成了新的 multipart boundary，重试的上传也会被重放。
