+# Copilot Instructions
+
+## Project overview
+
+- FastAPI service that mimics FlareSolverr-style API for bypassing anti-bot pages using Camoufox + Playwright captcha solver.
+- Entry point: main app in main.py; routes and request flow defined in src/endpoints.py and src/models.py.
+- Browser lifecycle is owned by get_camoufox() in src/utils.py, which yields a page, solver, and context for each request.
+
+## Architecture and data flow
+
+- Request flow: POST /v1 -> read_item() -> browser.goto() -> wait for load states -> detect challenge title -> solve captcha -> return LinkResponse.
+- Challenge detection uses CHALLENGE_TITLES from src/consts.py; update this map when adding providers.
+- Health check hits /v1 internally with <https://google.com> and fails if status is not OK.
+- Logging: LogRequest middleware logs only POST /v1 timing and outcome; other paths pass through.
+
+## Key modules and patterns
+
+- Models use Pydantic v2 with camelCase aliasing for responses (see src/models.py).
+- LinkResponse.invalid() is the standard error response shape; keep fields consistent with FlareSolverr style.
+- get_camoufox() constructs AsyncCamoufox with addons and optional proxy config from env vars.
+
+## Config and environment
+
+- Core env vars in src/consts.py: HOST, PORT, PROXY_SERVER, PROXY_USERNAME, PROXY_PASSWORD, LOG_LEVEL, VERSION.
+- VERSION strips leading "v" for tag-style values.
+
+## Developer workflows
+
+- Local run: uv sync && uv run main.py
+- Init mode: uv run main.py --init (pre-warms health check via browser setup)
+- Tests: uv sync --group test && uv run pytest --retries 3
+- Docker troubleshooting: docker build --target test .
+
+## Tests and external dependencies
+
+- tests/main_test.py calls real websites; tests are network-dependent and may be skipped based on upstream status.
+- HTTP client tests use starlette.testclient + httpx; avoid mocking unless needed for local-only changes.

 # Byparr

 > [!IMPORTANT]
-> Due to recent challenge changes, this software does not guarantee that the Cloudflare challenge will be bypassed. Cloudflare likely requires valid network traffic originating from the user’s public IP address to mark a connection as legitimate. While this tool may bypass the initial browser check, it does not ensure that requests will consistently pass Cloudflare's validation. More testing and data are required to understand how Cloudflare identifies connections and requests as valid. Invalid requests will result in Byparr's looping and eventually time-outing.
+> This software does not **guarantee** (only greatly increases the chance) that any challenge will be bypassed. While this tool passes the initial browser check, Cloudflare and other captcha providers likely require valid network traffic originating from the user’s public IP address to mark a connection as legitimate. If any website does not pass the challenge, please run troubleshooting steps and check if other websites work before you create an GitHub issue.

+
+#### Browser language
+
+Set `BROWSER_LOCALE` to a [BCP-47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt) language tag like `en-US`, `de-DE`, `fr-FR`, `pl-PL`, or `zh-CN` to fix the browser's language and `Accept-Language` header. When unset, Byparr derives the locale from the egress country (e.g. a French proxy → `fr-FR`), keeping the browser language consistent with the exit IP.
+
+Valid tags are maintained in the [IANA Language Subtag Registry](https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry). For a friendlier list, see [List of ISO 639-1 codes](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) (language) combined with an [ISO 3166-1 alpha-2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) region code for the full tag, e.g. `pt-BR`.
+
+## Proxy Recommendation
+
+Recently I've partnered with a _new in town_ proxy service - ProxyBase - to offer affordable proxy services that seems to work seamlessly with Byparr! Using my affiliate code `byparr` (case sensitive!) when signing up will not only get you access to their cost-effective (**$0.69/GB with occasional promotions** _at the time of writing_) proxy network but will also help support the continued development of this project. ProxyBase's proxies can significantly improve your success rate when bypassing anti-bot challenges. [Check out ProxyBase](https://client.proxybase.org/signup?ref=byparr) and enhance your Byparr experience!
+
+## Tags
+
+- `v*.*.*`/`latest` - Releases considered stable
+- `main` - Latest release from main branch (untested)
+- `pr-{number}` - Pull request images for testing (automatically cleaned up when PR closes)
+
+## Usage
 
 > [!IMPORTANT]
 > Support for NAS devices (like Synology) is minimal. Please report issues, but do not expect it to be fixed quickly. The only ARM device I have is a free Ampere Oracle VM, so I can only test ARM support on that. See [#22](https://github.com/ThePhaseless/Byparr/issues/22) and [#3](https://github.com/ThePhaseless/Byparr/issues/3)
 
-> [!NOTE]
-> Thanks to FastAPI implementation, now you can also see the API documentation at `/docs` or `/` (redirect to `/docs`) endpoints.
+### Docker Compose setup
+
+1. Review settings in `compose.yaml`.
+2. Start the service:
+
+```bash
+docker compose up -d
+```
+
+### Docker install
+
+1. Pull and run the image:
+
+   ```bash
+   docker run -p 8191:8191 ghcr.io/thephaseless/byparr:latest
+   ```
+
+2. Optional: set env vars using `-e` or `--env-file`.
+
+### Local install
+
+1. Install ([or update when Python version changes](https://github.com/astral-sh/uv/issues/17887)) [uv](https://docs.astral.sh/uv/getting-started/installation/).
+2. Clone this repo - `git clone https://github.com/ThePhaseless/Byparr`
+3. Run `uv run main.py`
+4. Enjoy!
+
+### API Docs
+
+Once running, open:
+
+- `http://localhost:8191/docs`
+- `http://localhost:8191/` (redirects to `/docs`)
+
+### Open WebUI Integration
+
+Byparr can serve as an external web loader for [Open WebUI](https://github.com/open-webui/open-webui), allowing it to fetch web content through Byparr's anti-bot bypassing capabilities.
+
+Configure Open WebUI with these environment variables:
+
+```bash
+WEB_LOADER_ENGINE=external
+EXTERNAL_WEB_LOADER_URL=http://byparr:8191/load
+EXTERNAL_WEB_LOADER_API_KEY=your-secret-key  # Optional, must match OWUI_API_KEY
+```
+
+The `/load` endpoint accepts `POST` requests with `{"urls": ["https://..."]}` and returns extracted text content for RAG pipelines.
