EchoDepth API (in development)
The EchoDepth API is in development and is not yet generally available. When it launches, engineering teams will be able to send video, audio, text and image content to EchoDepth and receive structured communication signal analysis inside their own platform. Until then, EchoDepth analysis is delivered through sample analyses, pilot programmes and enterprise engagements.
Updated October 2026
Planned authentication
The API is planned to use API key authentication for server-to-server calls, with OAuth 2.0 for user-facing applications. Authentication details, base URL and credential issuing will be published at launch.
Current status
There are no public SDKs, documentation or sandbox environment yet. Organisations that want to explore the approach can request a sample analysis or contact Cavefish to discuss early access.
Planned endpoints
These are planned and may change before launch.
Planned: submit a video file or URL for facial action unit analysis, returning Trust Score, Credibility Signal, Resistance Indicator and timestamped events.
Planned: submit audio for vocal pattern analysis, returning Confidence Score, Hesitation Map, Stress Indicators and timestamped vocal events.
Planned: submit a text string or document for linguistic credibility analysis, returning Sentiment Depth, Engagement Signal and hesitation markers.
Planned: submit one or more images for facial expression analysis, returning action unit classification per face and VAD coordinates.
Planned: submit any combination of video, audio, text and image in one request, returning a single Decision Intelligence report.
Planned: retrieve results for an asynchronous analysis job by job ID, for long-form video and audio.
Planned: WebSocket connection for real-time video stream analysis, returning per-frame action unit classifications.
Is the EchoDepth API available to use today?
No. The EchoDepth API is in development and is not yet generally available, so there are no public endpoints, SDKs or sandbox environment to integrate against today. Organisations that need communication signal analysis now can start with a free sample analysis or a pilot programme, and the API will be documented when it launches. The planned API covers video, audio, text, image and multimodal analysis, retrieval of results for long-form media, and a WebSocket stream for real-time video. Planned authentication uses API keys for server-to-server calls, with OAuth 2.0 for user-facing applications, and authentication details, base URL and credential issuing will be published at launch. Until then, EchoDepth analysis is delivered through sample analyses, pilot programmes and enterprise engagements, and organisations can request a sample analysis or contact Cavefish to discuss early access. Endpoint names and behaviour may change before launch, so the planned list should be treated as a plan rather than a reference.
Frequently asked questions
Is the EchoDepth API available to use today?
No. The EchoDepth API is in development and is not yet generally available. There are no public endpoints, SDKs or sandbox environment to build against yet. Organisations that need communication signal analysis now can start with a free sample analysis or a pilot programme.
What will the EchoDepth API cover?
The planned API covers video, audio, text, image and multimodal analysis, retrieval of results for long-form media, and a WebSocket stream for real-time video. Endpoint names and behaviour may change before launch, so treat the list on this page as a plan rather than a specification.
Which CRM and meeting tools will connect to EchoDepth?
Connectors for Salesforce, HubSpot, Microsoft Teams and Zoom depend on the API launch and are on the roadmap. Ask Cavefish for the current delivery options for your engagement.
Is EchoDepth GDPR compliant?
EchoDepth is UK GDPR compliant and registered with the ICO (ZB915633). Data processing for any engagement is governed by a Data Processing Agreement. The security page sets out current controls.
