For Agents

Submit audio and video files to cielo-24 for captioning and transcription, then retrieve transcripts, caption files, and word-level timecodes for downstream search or accessibility workflows.

Quickstart

Get started with cielo-24 API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{

Not supported: Does not handle video hosting, video editing, or live streaming — use for captioning and transcription of pre-recorded media only.

Jentic publishes the only available OpenAPI specification for cielo-24 API, keeping it validated and agent-ready. cielo-24 provides automated and human-verified captioning, transcription, and video intelligence services that turn audio and video files into searchable, indexed text. The API exposes job-based workflows for submitting media, requesting transcripts in multiple formats, retrieving an element list of words and timecodes, and managing account sessions. It is built around an account/login token model with eight job-management endpoints covering submission, status, retrieval, and deletion.

Use Cases

Patterns agents use cielo-24 API API for, with concrete tasks.

★ Accessible Video Captioning

Generate compliant closed captions for educational, corporate, and broadcast video libraries by submitting source media to cielo-24 and retrieving SRT or WebVTT files once the job completes. The /job/new and /job/perform_transcription endpoints handle high-fidelity captioning with human verification, and /job/get_transcript returns the formatted caption file ready for upload to a player or VOD platform.

Create a new cielo-24 job for an MP4 URL at high fidelity, poll /job/info until the job is complete, and download the SRT transcript via /job/get_transcript.

Video Search Indexing with Word-Level Timecodes

Make video libraries searchable by extracting word-level transcripts with start and end timestamps from cielo-24, then indexing the elements in a search engine so viewers can jump to the exact second a phrase is spoken. The /job/get_elementlist endpoint returns each word with its time offset, making this the source of truth for time-aligned video search.

Retrieve the element list for a completed cielo-24 job and emit one record per word with start_time, end_time, and word text for indexing into Elasticsearch.

Bulk Transcription Workflow Automation

Process large batches of media files through cielo-24 by automating job creation, media attachment, transcription kickoff, status polling, and transcript retrieval. The eight job endpoints cover the full lifecycle so an automation script can submit hundreds of files, monitor turnaround, and pull finished transcripts without manual touch.

Iterate over a list of 50 media URLs, call /job/new for each, attach the URL via /job/add_media, trigger /job/perform_transcription, then poll /job/info until all are complete.

AI Agent Captioning via Jentic

An AI agent receives a request to caption a podcast or video, searches Jentic for the captioning operation, loads the cielo-24 schema, and executes the job lifecycle without ever touching the API token directly. Jentic vaults the cielo-24 access credentials and returns a scoped session, and the agent gets a finished transcript URL or text payload back in a single workflow.

Use the Jentic search query 'transcribe a video file' to find the cielo-24 job submission operation, load its schema, and execute it with the source media URL and desired fidelity.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

cielo-24 account credentials and session tokens are stored encrypted in the Jentic vault. Agents receive a scoped access token for the duration of the workflow and never see the raw account password.

Intent-based discovery

Agents search Jentic by intent such as 'transcribe a video' and Jentic returns the matching cielo-24 job operations with their input schemas, so the agent calls the right endpoint without browsing cielo-24 docs.

Time to first call

Direct cielo-24 integration: 1-2 days to wire up login, job lifecycle, and transcript polling. Through Jentic: under 1 hour to search, load, and execute.

Real-time and batch speech-to-text API with speaker diarisation

Choose Deepgram when you need low-latency streaming transcription rather than human-verified captioning fidelity.

Complementary

FAQs

Specific to using cielo-24 API API through Jentic.

Why is there no official OpenAPI spec for cielo-24 API?

cielo24 does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call cielo-24 API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the cielo-24 API use?

The API uses an apiKey token obtained from /account/login that is then passed on subsequent job calls. Through Jentic the login credentials live in the encrypted vault and the agent only ever sees a scoped session token, never the raw account password.

Can I get word-level timecodes from cielo-24?

Yes. Once a transcription job completes, call /job/get_elementlist to receive each word with its start and end timecode, which is the basis for time-aligned video search and clip extraction.

What transcript formats can I download from cielo-24?

/job/get_transcript supports plain text, SRT, and WebVTT among other caption formats. The exact format is selected via the request parameters when retrieving the finished transcript.

How do I submit a new captioning job through Jentic?

Search Jentic for 'transcribe a video file', load the cielo-24 job submission schema, and execute against /job/new followed by /job/add_media and /job/perform_transcription. The Python SDK pattern is await client.search, await client.load, await client.execute.

How do I check whether a cielo-24 transcription job is finished?

Call /job/info with the job ID to read the current status, fidelity, and turnaround estimate. Poll this endpoint at a reasonable interval until the status indicates the transcript is ready to download.
