# Cerul API

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

# Quickstart

Replace YOUR_API_KEY with a Key created in Console, then run this request to list your videos. No upload is needed to verify access.

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

```

The response stores videos in data. An empty list is normal in a new workspace. With a ready video, continue to [Search](/docs.md?locale=en&page=search); otherwise [upload a video](/docs.md?locale=en&page=upload).

## Request parameters

| Field | Type · Required | Description |
| --- | --- | --- |
| Authorization | string · Required | Bearer YOUR_API_KEY |
| library_id | string · Optional | pattern: ^lib_[A-Za-z0-9_-]+$ |

## Reading the response

data[].id identifies the video. filename is its original name; status reports processing progress. ready means searchable, but inspect coverage and warnings for missing speech, visual or OCR evidence.

## Complete example

[Download complete example](/docs-quickstart.sh)

Run the snippets in the same Bash session with curl (7.76+), jq, Python 3 and ffprobe installed. Set talk.mp4 to your video. Processing and search consume credits; preserve the run ID when retrying unchanged requests.

Use https://api.cerul.ai without a /v1 prefix and send Authorization: Bearer <API_KEY>. Verify your account email before uploading, indexing, searching or exporting. Keys stay on your server; a Workspace shares one cloud wallet across Keys and authenticated app/CLI calls.

## Retries and errors

Send an Idempotency-Key of 8–200 characters where required, including search. Keep the same key and input after an ambiguous response; use a new key for a different operation/input. Poll pending jobs according to Retry-After and set a deadline. A client timeout does not cancel a server job.

• 401 · invalid_credentials: Check or replace the expired/revoked credential.

• 403 · permission_denied / insufficient_entitlement: Check scopes, verified email, entitlements and wallet balance.

• 429 · rate_limited: Back off using retry_after_seconds when present; check concurrency.

# Upload video

Place your video at talk.mp4 and replace YOUR_API_KEY. This request creates a video and reserves upload URLs using its real byte size; it does not upload the bytes yet.

```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}"

```

## Request parameters

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

Required scopes: assets:write.

## Upload the file bytes

Save data.id. For each entry in data.upload.parts, PUT the exact sequential byte range to its temporary URL using data.upload.required_headers. Do not send the API Key to the upload URL. Maximum file size is 5 GiB; URL ingestion is not supported.

[Download complete example](/docs-quickstart.sh)

Run the snippets in the same Bash session with curl (7.76+), jq, Python 3 and ffprobe installed. Set talk.mp4 to your video. Processing and search consume credits; preserve the run ID when retrying unchanged requests.

## Confirm the upload

After all parts succeed, POST /videos/{video_id}/complete with Bearer, Content-Type: application/json and a new Idempotency-Key. Submit the real duration and SHA-256. Completion starts indexing by default; do not submit a duplicate index request.

| Field | Type · Required | Description |
| --- | --- | --- |
| Authorization | string · Required | Bearer YOUR_API_KEY |
| duration_seconds | number · Required for indexing | Source duration, used for quota admission before transcription. — > 0 |
| content_sha256 | string · Required for indexing | 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 · Optional | false: upload only; true: start indexing — default: true |
| processing | object · Optional |  |
| processing.ocr | object · Optional |  |
| processing.ocr.enabled | boolean · Optional | Extract visible text as independently sampled evidence. Defaults to false. — default: false |
| processing.ocr.interval_seconds | integer · Optional | OCR sampling interval. Defaults to 10 seconds. — ≥ 1; ≤ 3600; default: 10 |
| execution_policy | string · Optional | local_only, prefer_local, cloud_allowed, cloud_required |
| video_id | string · Required | A Video is the developer-facing name for a media Asset, and shares its identifier. — pattern: ^asset_[A-Za-z0-9_-]+$ |
| Idempotency-Key | string · Required | minLength: 8; maxLength: 200 |

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

Indexing additionally requires jobs:write, assets:read and artifacts:write. Set index:false only to retain an unindexed upload; later use POST /videos/{video_id}/index.

## Wait for indexing

Poll GET /videos/{video_id} with a deadline: ready is searchable; failed means inspect error; processing means wait. A client timeout does not cancel the server job.

OCR is off by default. Set OCR_ENABLED=true before completion to index visible text at a 10-second interval. A ready video is searchable; inspect coverage and warnings for missing speech, visual or OCR evidence. A video without audio has no transcript.

---

# Search

Replace YOUR_API_KEY and YOUR_VIDEO_ID to search a ready video. Keep REQUEST_KEY unchanged when retrying the same request.

```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
  }'

```

## Request parameters

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

Required scopes: libraries:read, assets:read.

## Read the result

Each data item contains evidence and score. evidence.id identifies the evidence; asset_id identifies its source. start_seconds and end_seconds locate it in the video. quote is the evidence text; kind and modality distinguish speech, OCR and visual evidence. score ranks relevance and is not a correctness probability.

Keep request_id, usage and warnings. Display source, timestamps and evidence text, and verify the original clip before using it. Export a bounded span with [clips](/docs.md?locale=en&page=clips).

## No matches

An empty data array is not a request failure. Check readiness, filter and coverage before refining the query. A valid completed search may be charged without matches; a request with no indexed evidence is not charged. GET /videos/{video_id}/transcript reads speech; no audio may return 422 no_audio_track.

---

# Export and manage

Replace the Key and video ID to request a clip from 30 to 45 seconds. Confirm the source contains this range. The response creates an asynchronous job, not a ready download.

```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}'

```

## Request parameters

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

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

## Wait and download

Save data.id as JOB_ID. Poll GET /jobs/{job_id}, honoring Retry-After and a deadline. On succeeded, GET /jobs/{job_id}/artifacts and select the clip by its type and metadata. Download GET /artifacts/{artifact_id}/content using Bearer authentication. Reading jobs needs jobs:read; reading artifacts needs artifacts:read. Stop on failed or canceled.

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

## Cancel or delete

POST /jobs/{job_id}/cancel requests cancellation; keep polling to a terminal state. DELETE /videos/{video_id} cleans up a video and associated data (assets:write). DELETE /artifacts/{artifact_id} deletes one artifact (artifacts:write). After a 202 deletion receipt, poll GET /deletions/{deletion_id} until cleanup completes.

Successful searches may be charged even with no matches; no indexed evidence means no search charge. Failed or canceled processing can still settle completed billable work and release unused reservations. Deletions return 202: follow the deletion receipt until cleanup finishes. Read available, reserved and debt credits separately in /billing/wallet.
