# WaveSign API

Private API space — not publicly accessible.

All endpoints (except `/health`) require an `Authorization: Bearer <key>` header matching the `WS_API_KEY` environment variable configured for this Space.

## Endpoints

- `GET /health` — liveness check, no auth required
- `POST /sign` — sign an image or PDF; returns a ZIP containing the signed file and `sig.json`
- `POST /verify` — verify a previously signed file against its `sig.json`; returns a JSON result
