# tryVidimus API documentation > Capture photos and videos during a transaction, seal them as proofs that anyone can verify independently, and read them back through a simple JSON API. The documentation is available in English and French: replace `/en` with `/fr` in a page address. ## Documentation - [Overview](https://docs.tryvidimus.com/en): Capture photos and videos during a transaction, seal them as proofs that anyone can verify independently, and read them back through a simple JSON API. - [Capture templates and languages](https://docs.tryvidimus.com/en/templates): Define what the capture page asks for, in every language of your users: the shots to take and the texts, with a fallback when a language is missing. - [Before and after](https://docs.tryvidimus.com/en/before-after): Link the capture of an item at hand-over to its capture at return, with the same shots and at least as many photos. - [Balance and usage](https://docs.tryvidimus.com/en/credits): Your balance is in euros. See what is left, what was debited, and how each proof is counted. - [Return to your app](https://docs.tryvidimus.com/en/return): Take the person back to your application once the photos are taken, and be told on your server when the capture is over. - [Mobile apps](https://docs.tryvidimus.com/en/mobile): Open the capture page from an iPhone or Android app, give it the camera, and bring the person back to your app. - [Packages and libraries](https://docs.tryvidimus.com/en/sdk): The command line, the MCP server and the TypeScript libraries are published on npm under the MIT licence. The API is plain JSON over HTTPS: call it directly or generate a client. - [MCP and integrations](https://docs.tryvidimus.com/en/integrations): Use the API from Claude (MCP), from ChatGPT (a custom GPT with an Action), from Postman or from the command line. - [API reference](https://docs.tryvidimus.com/en/api): Every route, field and error of the API, with examples. Send real calls from your browser with a sandbox key. ## API - [OpenAPI schema](https://api.tryvidimus.com/openapi.json): The machine-readable contract (OpenAPI 3.1), to generate a client or import into Postman. Add `?lang=fr` for the French version. ## Contact - Support: support@tryvidimus.com
