+### v1
+
+Ce web-service renvoie la liste des entités nommées en chimie présentes dans le texte.
+
+Il prend en entrée du JSON avec deux champs, `id` et `value`, et renvoie un JSON avec le la liste des entités en fonction de leur étiquettes dans le champ `value`.
+
+#### Exemple de v1/first-name/gender
+
+Entrée
+
+```bash
+$ cat <<EOF | curl -X POST --data-binary @- "?????????"
+[{"id": "1", "value": "This is three chemical name entity: methanol, 2-propanol, or CO2."}]
+EOF
+```
+
+Sortie
+
+```json
+[
+  {"id": 1, "value": {"chemical": ["methanol","2-propanol","CO2"], "chemical_disambiguisate": ["methanol","propan-2-ol"]}}
+]
