# Cerul API

Documentation: https://cerul.ai/docs
Base URL: https://api.cerul.ai (no /v1).

# 快速開始

將 YOUR_API_KEY 換成在 Console 建立的 Key，直接執行以下請求即可列出影片，無需先上傳檔案。

```bash
curl --fail-with-body "https://api.cerul.ai/videos" \
  -H "Authorization: Bearer YOUR_API_KEY"

```

影片清單位於 data；新工作區回傳空清單是正常結果。已有 ready 影片可直接[搜尋](/docs.md?locale=zh-Hant&page=search)，否則先[上傳影片](/docs.md?locale=zh-Hant&page=upload)。

## 請求參數

| 參數 | 類型 · 必填 | 說明 |
| --- | --- | --- |
| Authorization | string · 必填 | Bearer YOUR_API_KEY |
| library_id | string · 選填 | pattern: ^lib_[A-Za-z0-9_-]+$ |

## 閱讀回傳結果

data[].id 是影片 ID；filename 是檔名；status 表示處理狀態。ready 表示可搜尋，但仍需檢查 coverage 和 warnings，確認語音、畫面和 OCR 的實際結果。

## 完整範例

[下載完整範例](/docs-quickstart.sh)

請在同一個 Bash 工作階段執行，需要 curl（7.76+）、jq、Python 3 與 ffprobe。影片放在 talk.mp4。處理與搜尋會消耗額度；重試相同請求時保留本次 run ID。

基礎位址為 https://api.cerul.ai，不含 /v1；標頭使用 Authorization: Bearer <API_KEY>。上傳、索引、搜尋或匯出前先驗證帳號信箱。Key 僅放伺服器端；同一 Workspace 的 Key、網頁與 CLI 雲端呼叫共用錢包。

## 重試與錯誤

依介面要求傳送 8–200 字元的 Idempotency-Key，搜尋也需要。回應不確定時保留原鍵與原輸入；不同操作或輸入使用新鍵。輪詢未完成工作時遵循 Retry-After 並設定期限。用戶端逾時不會取消伺服器工作。

• 401 · invalid_credentials: 確認憑證是否錯誤、過期或已撤銷。

• 403 · permission_denied / insufficient_entitlement: 檢查權限、信箱驗證、權益與錢包餘額。

• 429 · rate_limited: 若回傳 retry_after_seconds，依其退避；檢查並行限制。

# 上傳影片

將影片放在 talk.mp4 並替換 YOUR_API_KEY。此請求使用真實檔案大小建立影片並取得上傳網址，尚未傳送檔案內容。

```bash
REQUEST_KEY="upload-$(uuidgen)"
FILE_SIZE=$(wc -c < ./talk.mp4 | tr -d ' ')
curl --fail-with-body "https://api.cerul.ai/videos" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $REQUEST_KEY" \
  -d "{\"filename\":\"talk.mp4\",\"media_type\":\"video/mp4\",\"byte_size\":$FILE_SIZE}"

```

## 請求參數

| 參數 | 類型 · 必填 | 說明 |
| --- | --- | --- |
| Authorization | string · 必填 | Bearer YOUR_API_KEY |
| filename | string · 必填 | minLength: 1; maxLength: 255 |
| media_type | string · 必填 | minLength: 3; maxLength: 127; pattern: ^[Vv][Ii][Dd][Ee][Oo]/[A-Za-z0-9][A-Za-z0-9!#$&^_.+-]*$ |
| byte_size | integer · 必填 | ≥ 1; ≤ 5368709120 |
| library_id | string · 選填 | Omit to file the video in the workspace default library. — pattern: ^lib_[A-Za-z0-9_-]+$ |
| execution_policy | string · 選填 | local_only, prefer_local, cloud_allowed, cloud_required |
| Idempotency-Key | string · 必填 | minLength: 8; maxLength: 200 |

Required scopes: assets:write.

## 上傳檔案內容

保存 data.id。依 data.upload.parts 順序，將精確的位元組區間 PUT 到臨時網址，並使用 data.upload.required_headers。不要將 API Key 傳送至上傳網址。單檔最大 5 GiB，不支援 URL 匯入。

[下載完整範例](/docs-quickstart.sh)

請在同一個 Bash 工作階段執行，需要 curl（7.76+）、jq、Python 3 與 ffprobe。影片放在 talk.mp4。處理與搜尋會消耗額度；重試相同請求時保留本次 run ID。

## 確認上傳完成

所有分片成功後，呼叫 POST /videos/{video_id}/complete，附上 Bearer、Content-Type: application/json 和新的 Idempotency-Key，提交真實時長及 SHA-256。確認完成預設啟動索引，不要重複提交索引請求。

| 參數 | 類型 · 必填 | 說明 |
| --- | --- | --- |
| Authorization | string · 必填 | Bearer YOUR_API_KEY |
| duration_seconds | number · 索引時必填 | Source duration, used for quota admission before transcription. — > 0 |
| content_sha256 | string · 索引時必填 | Declares source identity for indexing. The Worker verifies it against the uploaded bytes and successful unique-material billing is deduplicated by this hash; a distinct video asset may still be processed independently. — pattern: ^[a-fA-F0-9]{64}$ |
| index | boolean · 選填 | false: upload only; true: start indexing — default: true |
| processing | object · 選填 |  |
| processing.ocr | object · 選填 |  |
| processing.ocr.enabled | boolean · 選填 | Extract visible text as independently sampled evidence. Defaults to false. — default: false |
| processing.ocr.interval_seconds | integer · 選填 | OCR sampling interval. Defaults to 10 seconds. — ≥ 1; ≤ 3600; default: 10 |
| execution_policy | string · 選填 | local_only, prefer_local, cloud_allowed, cloud_required |
| video_id | string · 必填 | A Video is the developer-facing name for a media Asset, and shares its identifier. — pattern: ^asset_[A-Za-z0-9_-]+$ |
| Idempotency-Key | string · 必填 | minLength: 8; maxLength: 200 |

Required scopes: assets:write, library-items:write.

索引另需 jobs:write、assets:read、artifacts:write。僅保存影片時設 index:false，之後可呼叫 POST /videos/{video_id}/index。

## 等待索引

以截止時間輪詢 GET /videos/{video_id}：ready 可搜尋，failed 時檢查 error，processing 時繼續等待。用戶端逾時不會取消服務端工作。

OCR 預設關閉。完成上傳前設定 OCR_ENABLED=true，即可每 10 秒取樣畫面文字。ready 表示可搜尋；請檢查 coverage 與 warnings，確認語音、畫面和 OCR 的實際覆蓋。沒有音軌的影片沒有轉錄。

---

# 搜尋

替換 YOUR_API_KEY 和 YOUR_VIDEO_ID 即可搜尋已就緒影片。重試相同請求時保留 REQUEST_KEY。

```bash
REQUEST_KEY="search-$(uuidgen)"
curl --fail-with-body "https://api.cerul.ai/search" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $REQUEST_KEY" \
  -d '{
    "query": "When did they discuss scaling laws?",
    "filter": {"video_ids": ["YOUR_VIDEO_ID"]},
    "limit": 5
  }'

```

## 請求參數

| 參數 | 類型 · 必填 | 說明 |
| --- | --- | --- |
| Authorization | string · 必填 | Bearer YOUR_API_KEY |
| query | string · 必填 | minLength: 1; maxLength: 1000 |
| filter | object · 選填 | Omit to search the whole workspace. |
| filter.video_ids | array · 選填 | uniqueItems |
| filter.library_ids | array · 選填 | uniqueItems |
| execution_policy | string · 選填 | local_only, prefer_local, cloud_allowed, cloud_required |
| limit | integer · 選填 | ≥ 1; ≤ 100; default: 20 |
| Idempotency-Key | string · 必填 | minLength: 8; maxLength: 200 |

Required scopes: libraries:read, assets:read.

## 閱讀結果

每個 data 項目包含 evidence 與 score。evidence.id 標識證據，asset_id 標識來源；start_seconds 和 end_seconds 是影片中的起止秒數。quote 是證據文字，kind 和 modality 區分語音、OCR 與畫面。score 是相關性排序，不是正確機率。

保留 request_id、usage 和 warnings。展示來源、時間與證據文字，先核對原片段，再[匯出剪輯](/docs.md?locale=zh-Hant&page=clips)。

## 沒有命中

data 空陣列不等於請求失敗。先檢查就緒狀態、篩選與 coverage，再調整查詢。有效檢索無命中仍可能收費；沒有已索引證據則不收搜尋費。GET /videos/{video_id}/transcript 讀取語音轉錄，無音軌可能回傳 422 no_audio_track。

---

# 匯出與管理

替換 Key 與影片 ID，建立 30–45 秒的剪輯。請先確認原影片包含此範圍；回傳的是非同步工作，不是已完成的下載。

```bash
REQUEST_KEY="clip-$(uuidgen)"
curl --fail-with-body "https://api.cerul.ai/clips" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $REQUEST_KEY" \
  -d '{"video_id":"YOUR_VIDEO_ID","start_s":30,"end_s":45}'

```

## 請求參數

| 參數 | 類型 · 必填 | 說明 |
| --- | --- | --- |
| Authorization | string · 必填 | Bearer YOUR_API_KEY |
| video_id | string · 必填 | A Video is the developer-facing name for a media Asset, and shares its identifier. — pattern: ^asset_[A-Za-z0-9_-]+$ |
| start_s | number · 必填 | ≥ 0 |
| end_s | number · 必填 | > 0 |
| evidence_ids | array · 選填 | maxItems: 100; uniqueItems |
| execution_policy | string · 選填 | local_only, prefer_local, cloud_allowed, cloud_required |
| Idempotency-Key | string · 必填 | minLength: 8; maxLength: 200 |

Required scopes: jobs:write, assets:read, artifacts:write.

## 等待與下載

保存 data.id 為 JOB_ID。依 Retry-After 和截止時間輪詢 GET /jobs/{job_id}。succeeded 後呼叫 GET /jobs/{job_id}/artifacts，按類型與中繼資料選擇剪輯，再以 Bearer 下載 GET /artifacts/{artifact_id}/content。查詢工作需 jobs:read，讀取產物需 artifacts:read。failed 或 canceled 時停止輪詢。

```bash
curl --fail-with-body "https://api.cerul.ai/artifacts/YOUR_ARTIFACT_ID/content" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --output clip.mp4
```

## 取消或刪除

POST /jobs/{job_id}/cancel 請求取消，需持續查詢到終態。DELETE /videos/{video_id} 清理影片與關聯資料（assets:write）；DELETE /artifacts/{artifact_id} 刪除單個產物（artifacts:write）。收到 202 刪除回執後，輪詢 GET /deletions/{deletion_id} 直到清理完成。

成功檢索即使沒有命中也可能收費；沒有已索引證據的請求不收搜尋費。失敗或取消仍可能結算成功處理的部分，並釋放剩餘預留。刪除回傳 202 後應持續查詢回執直到清理完成。透過 /billing/wallet 分別查看可用、預留與欠款額度。
