+# Demographic Functions
+
+The Demographic Snapshot enables you to collect demographic reports around a point location. For example, you can take the coordinates of a coffee shop and find the average population characteristics, such as total population, educational attainment, housing and income information around that location. You can use raw street addresses by combining the Demographic Snapshot with CARTO's geocoding features. If you need help creating coordinates from addresses, see the [Geocoding Functions](https://carto.com/docs/carto-engine/dataservices-api/geocoding-functions/) documentation.
+
+_**Note:** The Demographic Snapshot functions are only available for the United States._
+
+## OBS_GetDemographicSnapshot( point geometry )
+
+Fields returned include information about income, education, transportation, race, and more. Not all fields will have information for every coordinate queried.
+
+### Arguments
+
+Name | Description | Example Values
+--- | --- | ---
+point geometry | A point geometry. You can use the helper function, `CDB_LatLng` to quickly generate one from latitude and longitude | `CDB_LatLng(40.760410,-73.964242)`
+
+### Returns
+
+The Demographic Snapshot contains a broad subset of demographic measures in the Data Observatory. Over 80 measurements are returned by a single API request. For each demographic measure, the API returns the following values.
+
+Value | Name | Tablename | Aggregate | Type | Description
+----- | ---- | --------- | --------- | ---- |------------
+The value of the measure at the point you requested | The name of the measure | The table it was drawn from | Indicated if the measure is a count or median. | postgresql | A description of the measure
+
+For example the "Female Population" measure returns
+
+```json
+obs_getdemographicsnapshot: {
+   "value": 32.5395066379175,
+   "name": "Female Population",
+   "tablename": "obs_1a098da56badf5f32e336002b0a81708c40d29cd",
+   "aggregate": "sum",
+   "type": "Numeric",
+   "description": "The number of people within each geography who are female."
+}
+```
+
+**For details, see the [Glossary of Demographic Measures](#glossary-of-demographic-measures).**
+
+### Examples
+
+```bash
+https://{username}.carto.com/api/v2/sql?q=SELECT * FROM
+OBS_GetDemographicSnapshot({{point geometry}})
+```
+
+##### Get the Geographic Snapshot of a Demographic

+# Exception-Safe functions
+
+The public API dataservices functions emit exceptions in general when an error occurs
+or a limiting condition is met (e.g. quotas are exceeded).
+
+For each public function `func` we have a internal function named `_func_exception_safe` which
+acts as a wrapper to the public function, with the same signature, but captures
+exceptions generated during its execution (except those due to incomplete configuration or
+authentication issues) and returns NULL or empty set values in those cases.
+
+Please note these functions are considered **not public** and therefore their API (including which exceptions are wrapped and which ones are not) may change.
+
+Instead of raising an exception they raise warnings, hopefully containing the same information of the original exception.
+
+## Intended Use
+
+These functions are useful in cases when it is undesirable to rollback a transaction.
+Fo example if a table is geocoded with:
+
+```sql
+UPDATE table SET the_geom=cdb_geocode_street_point(user,NULL,address,city,NULL,country);
+```
+
+In case of the user geocoding quota being exhausted mid-process, the user could
+incur in external service expenses but any geocoded data would be lost due to the
+transaction rollback.
+
+We can avoid the problem using the corresponding exception-safe function:
+
+```sql
+UPDATE table SET the_geom=_cdb_geocode_street_point_exception_safe(user,NULL,address,city,NULL,country);
+```

+All the services from Dataservices API are subject to quota management: check, limit, etc.
+
+There are three main fields in the quota management:
+
+- **Quota**: Number of requests of this kind the user could make, eg. Number of street geocoding requests
+- **Soft limit**: This flag enables the user to surpass their assigned quota. When this flag is activated, there is no quota check so the user could make all the requests that they want. Consequently, the `hard_limit` flag, when enabled, indicates that the user cannot surpass the assigned quota.
+- **Block price**: Price for every 1000 requests
+
+
+All the user/organization quota information is stored in the user metadata in Redis but managed by the CartoDB Rails app through the User/Organization models. Nevertheless you could change/read the Redis information through the following keys:
+
+- `hgetall rails:users:username`
+- `hgetall rails:orgs:orgname`
+
+This whole information is managed by the CartoDB Rails App too so we could make a numer of useful operations in order to know how much quota do you have, how much quota have you spent this month and so on.
+
+###How can I know the current quota, number of uses, etc for a user?###
+
+You could use the following endpoint to know it: https://<username>.cartodb.com/api/v1/users/<user_id>?api_key=<api_key>
+In the result of this endpoint you can see blocks with all the information. Eg:
+
+```
+"geocoding": {
+    "quota": 1000,
+    "block_price": 1500,
+    "monthly_use": 743,
+    "hard_limit": true
+}
+```
+
+### How can I set a new quota for a user###
+
+This operation could be done through the rails console:
+
+- First you have to connect to the rails console: `bundle exec rails c`
+- Once in the console you have to get the target user/organization:
+  - `u = User.find(username: '<username>')`
+  - `o = Organization.find(name: '<orgname>')`
+- After we have the user/organization, we could change the quota or the hard limit flag for the desired service. I'm going to use geocoding as an example but it could be done with all the services:
+
+  ```
+     u.geocoding_quota = 2000
+     [u.soft_geocoding_limit = true|false]
+     u.save
+     ```
+  ```
+     o.geocoding_quota = 2000
+     o.save
+    ```
+- This way the user now has 2000 requests as their current quota
+- We can only change the hard limit flag for users, not for organizations
+
+### What services we could change?###
+
+  The following list numbers all the current services but this is a living list so it could keep growing in the future:
+
+  - Geocoding (street level): `geocoding_quota`, `soft_geocoding_limit`
+  - Isolines: `here_isolines_quota`, `soft_here_isolines_limit`
+  - Data observatory snapshot: `obs_snapshot_quota`, `soft_obs_snapshot_limit`
+  - Data observatory general: `obs_general_quota`, `soft_obs_general_limit`
+
+### How is the quota spent?###
+
+Almost in all the services: geocoding, data observatory snapshot and general the number of spent credits is calculated per request made (either successful or empty request).
+
+In the case of the isolines service, the number of credits is calculated based on the number of isolines generated by the request. Ie. If your query generates 3 isolines for the request, you've spent 3 isolines credits.

 # Isoline Functions

-[Isolines](https://cartodb.com/data/isolines/) are contoured lines that display equally calculated levels over a given surface area. This enables you to view polygon dimensions by forward or reverse measurements. Isoline functions are calculated as the intersection of areas from the origin point, measured by distance (isodistance) or time (isochrone). For example, the distance of a road from a sidewalk. Isoline services through CartoDB are available by requesting a single function in the Data Services API.

 # Overview

-By using CartoDB libraries and the SQL API, you can apply location data services to your maps with unique data services functions. These functions are integrated with a number of internal and external services, enabling you to programatically customize subsets of data for your visualizations. These features are useful for geospatial analysis and the results can be saved, and stored, for additional location data service operations.

These features are useful for geospatial analysis and the results can be saved, and stored, for additional location data service operations.

 ## Data Services Integration

 By using the SQL API to query the Data Services API functions, you can manage specific operations and the corresponding geometries (a `polygon` or a `point`), according to the input information.

-The Data Services API decouples the geocoding and isoline services from the CartoDB Editor. The API allows you to geocode data (from single rows, complete datasets, or simple inputs) and to perform trade areas analysis (computing isodistances or isochrones) programatically, through authenticated requests.
+The Data Services API also exposes its services directly through CARTO Builder. For example, you can geocode data (from single rows, complete datasets, or simple inputs) and perform trade areas analysis (computing isodistances or isochrones) programatically, through authenticated SQL requests, or by using the ANALYSIS options. 

 The geometries provided by this API are projected in the projection [WGS 84 SRID 4326](http://spatialreference.org/ref/epsg/wgs-84/).

-**Note:** The Data Services API [geocoding functions](http://docs.cartodb.com/cartodb-platform/dataservices-api/geocoding-functions/#geocoding-functions) return different types of geometries (points or polygons) as result of different geocoding processes. The CartoDB Platform does not support multi-geometry layers or datasets, therefore you must confirm that you are using consistent geometry types inside a table, to avoid future conflicts in your map visualization.

 ### Best Practices

 _Be mindful of the following usage notes when using the Data Services functions with the SQL API:_

-It is discouraged to use the SELECT operation with the Data Services API functions in your map layers, as these type of queries consume quota when rendering tiles for your live map views. It may also result in sync performance issues, due to executing multiple requests to the API each time your map is viewed. See details about [Quota Consumption](http://docs.cartodb.com/cartodb-platform/dataservices-api/quota-information/#quota-consumption).

See details about [Quota Consumption](https://carto.com/docs/carto-engine/dataservices-api/quota-information/#quota-consumption).

 The Data Services API is **recommended** to be used with INSERT or UPDATE operations, for applying location data to your tables. While SELECT (retrieve) is standard for SQL API requests, be mindful of quota consumption and use INSERT (to insert a new record) or UPDATE (to update an existing record), for best practices.

 ## Authentication

-All requests performed to the CartoDB Data Services API must be authenticated with the user API Key. For more information about where to find your API Key, and how to authenticate your SQL API requests, view the [SQL API authentication](/cartodb-platform/sql-api/authentication/) documentation.

+# Segmentation Functions
+
+The Segmentation Snapshot functions enable you to determine the pre-calculated population segment for a location. Segmentation is a method that divides a populations into subclassifications based on common traits. For example, you can take the a store location and determine what classification of population exists around that location. If you need help creating coordinates from addresses, see the [Geocoding Functions](https://carto.com/docs/carto-engine/dataservices-api/geocoding-functions/) documentation.
+
+_**Note:** The Segmentation Snapshot functions are only available for the United States. Our first release (May 18, 2016) is derived from Census 2010 variables. Our next release will be based on Census 2014 data. For the latest information, see the [Open Segments](https://github.com/CartoDB/open-segments) project repository._

+Name | Description | Example Values
+--- |  --- | ---
+point geometry | A point geometry. You can use the helper function, `CDB_LatLng` to quickly generate one from latitude and longitude | `CDB_LatLng(40.760410,-73.964242)`
+
+### Returns
+
+The segmentation function returns two segment levels for the point you requests, the x10\_segment and x55\_segment. These segmentation levels contain different classifications of population within with each segment. The function also returns the quantile of a number of census variables. For example, if total_poulation is at 90% quantile level then this tract has a higher total population than 90% of the other tracts. 
+
+Name | Type | Description
+---- | ---- | -----------
+x10\_segment | text | The demographic segment location at the 10 segment level, containing populations at high-levels, broken down into 10 broad categories
+x55\_segment | text | The demographic segment location at the 55 segment level, containing more granular sub-levels to categorize the population
