+# Google search metacrawl
+
+Proof-of-concept.
+
+Server exposes a single endpoint `/metacrawl` which takes a search term `q`
+as argument and returns a JSON response.
+
+Build and run docker:
+
+```bash
+$ docker build -t metacrawl:0.1
+$ docker run --rm -it -p 5000:5000 metacrawl:0.1
+```
+
+Query server:
+
+```bash
+$ curl localhost:5000/metacrawl?q=yolo
+{"metadescription":"An overused acronym for \"You only live once.\" There is an exception for those who believe in reincarnation or are cats.","metatitle":"Urban Dictionary: YOLO"}
+```
