- Created migration scripts to establish the `upstream_providers` table and integrate it with the `models` table.
- Enhanced the proxy functionality to support dynamic upstream provider initialization and model resolution.
- Implemented API endpoints for managing upstream providers, including CRUD operations and model fetching.
- Refactored pricing calculations to accommodate upstream provider overrides and ensure accurate cost estimation.
- Updated the admin interface to allow for easy management of upstream providers and their associated models.
This flag fetch all keysets from the db into the wallet, which is wrong given that we're initiating it for a mint. And load_mint sets the first keyset from all the keysets from the db, irrespective of the unit and the mint.
Fixes#175
## Routstr v0.1.3 — 2025-09-15
### Highlights
- **DB-backed settings with live updates**: Env vars seed on first run; DB is the source of truth (except `DATABASE_URL`). Manage via Admin UI or `PATCH /admin/api/settings`.
- **Models moved to database** with background sats-pricing computation and optional periodic refresh.
- **Smarter max-cost reservation**: Discount based on prompt tokens and `max_tokens` using `TOLERANCE_PERCENTAGE`, with a `MIN_REQUEST_MSAT` floor.
- **Faster startup and provider discovery**; `.onion` endpoints use Tor proxy by default.
### Breaking changes
- **Configuration is DB-first** after bootstrap. Env changes won’t auto-apply (besides `DATABASE_URL`).
- **Models endpoint**: Use `/v1/models` for canonical model info; `/v1/info` keeps an empty `models` field for back-compat.
- **Legacy pricing envs** are auto-mapped but deprecated:
- `MODEL_BASED_PRICING` → `!FIXED_PRICING`
- `COST_PER_REQUEST` → `FIXED_COST_PER_REQUEST`
- `COST_PER_1K_*` → `FIXED_PER_1K_*`
### Added
- **SettingsService** with env→computed→DB merge; runtime edits; app metadata (name/description) applied to OpenAPI.
- **Automatic migrations** on startup; new tables: `settings`, `models`.
- **Per-model sats pricing** and per-request maximums computed in the background.
- **Pricing controls**: `FIXED_PRICING`, `FIXED_COST_PER_REQUEST`, optional per-1k token overrides, `MIN_REQUEST_MSAT`.
- **Azure chat support**: Optional `CHAT_COMPLETIONS_API_VERSION` adds `api-version` to `/chat/completions`.
- **Derive `NPUB` from `NSEC`** during bootstrap if not provided.
### Changed / Improvements
- **Proxy header hardening**: Strip sensitive headers; replace Authorization with upstream key when configured.
- **Discovery**: Read `RELAYS` from settings; Tor proxy defaults for `.onion` via `TOR_PROXY_URL`; faster announcement fetching.
- **Admin**: Improved auth/log UX; fixed log search; show mint balances in dashboard.
- **Performance**: Optimized startup; lazy DB info loading.
### Fixed
- **Refunds**: Correct msat→sat conversion; configurable refund cache TTL via `REFUND_CACHE_TTL_SECONDS`; better error mapping for mint outages.
- **Balances**: Reserved balance reporting and negative-reserved edge cases.
- **Tests**: Updated to patch settings and use fixed-pricing flags.
### Upgrade notes (from v0.1.2)
1. Ensure `DATABASE_URL`, `UPSTREAM_BASE_URL`, and `ADMIN_PASSWORD` are set. Optionally set `UPSTREAM_API_KEY`, `RELAYS`, `CASHU_MINTS`, `TOR_PROXY_URL`.
2. Start the service; automatic Alembic migrations will run (`settings`, `models` tables).
3. Configure settings via Admin UI (`/admin`) or `PATCH /admin/api/settings`. Env changes after first run won’t apply automatically.
4. Prefer new pricing envs or a `models.json` at `MODELS_PATH`. Legacy envs are mapped but will be removed in a future release.
5. Optional tuning: `TOLERANCE_PERCENTAGE`, `MIN_REQUEST_MSAT`, `PRICING_REFRESH_INTERVAL_SECONDS`, `MODELS_REFRESH_INTERVAL_SECONDS`, `ENABLE_*_REFRESH`.
6. For Azure, set `CHAT_COMPLETIONS_API_VERSION`.
