evidentia-api 0.8.3

FastAPI REST server + bundled React web UI for Evidentia

evidentia-api

FastAPI REST server and bundled React web UI for Evidentia, the open-source GRC tool.

This package is not typically installed directly. The preferred way is via the [gui] extra on the meta-package:

uv tool install "evidentia[gui]"
# or
pip install "evidentia[gui]"

Then run:

evidentia serve
# -> FastAPI + React UI at http://127.0.0.1:8000

What's inside

• FastAPI app (evidentia_api.app:app) — REST endpoints mirroring every CLI capability.
• SPA — React/Vite/shadcn/ui frontend, bundled as static assets inside the wheel under evidentia_api/static/.
• SSE streaming — long-running LLM calls (risk generate, explain) stream progress to the browser without blocking.

REST surface

Every endpoint is typed with Pydantic models reused from evidentia-core. All endpoints bind to 127.0.0.1 by default; --host 0.0.0.0 emits a security warning.

Air-gapped mode

Running evidentia serve --offline wires the air-gap guard into every /api/* call. LLM features gracefully degrade with a pointer to Ollama. See docs/air-gapped.md.
