The set of tools you will use to develop custom applications with CARTO
deck.gldeck.gl is an open source JavaScript (and TypeScript) based visualization library designed for large-scale geospatial datasets. It's powered by WebGL2 and WebGPU, achieving incredible visual results with high performance. It's part of the vis.gl framework, integrated into the . CARTO is a lead contributor as well as a member of the technical steering committee of deck.gl.
To visualize geospatial data from CARTO in a custom web application, you need to use deck.gl.
@deck.gl/cartoInside deck.gl, we maintain our CARTO module, which provides all the necessary layers and styling functions to create and style layers from your CARTO connections.
@carto/api-client@carto/api-client is a JavaScript (and TypeScript) client library for CARTO APIs and framework-agnostic web applications.
SQL APICARTO SQL API v3 lets you run arbitrary queries in external data warehouses using an existing connection in your CARTO organization.
Tokens APIThe CARTO Tokens API allows the creation API Access Tokens that grant access to specific tables, tilesets and arbitrary queries using a specific connection in your CARTO organization.
An API Access Token allows to create map layers and fetch data from tables, tilesets or arbitrary SQL queries in public applications.
Connections APICARTO Connections API allows for programmatically managing (create, list, delete, or update) your connections to an external Data Warehouse
Imports APICARTO Imports API allows the creation of geospatial tables in an organization's CARTO Data Warehouse by importing files via URL. Once a file is imported, the resulting table can be previewed in Data Explorer and used in Builder and external applications to create maps.
When using the carto_dw connection in your CARTO organization it will create tables in your organization's data shared folder. Learn more about CARTO Data Warehouse .
Currently, supported file formats are CSV, GeoJSON, GeoParquet and Shapefile; This last one needs to be packaged in a .zip file.
Other supported Data Warehouses are BigQuery, Snowflake, Amazon Redshift and PostgreSQL
There is a size limit to the files that can be imported. It's currently set at 1GB. if you need a higher limit.
Location Data Services (LDS API)CARTO Location Data Services API provides access to the following services:
Geocoding: Get coordinates from a street address
Batch geocoding: Get coordinates from a list of street addresses
Reverse geocoding: Get a street address from a pair of coordinates
Isolines: Get isoline geometries for different methods of transportation.
Maps APIOur SaaS platform is protected with a web application firewall (WAF) that will automatically and temporarily block any IP that exceeds our API rate limits. Said API rate limits are:
Maps API: 3500 requests/minute
SQL API: 2500 requests/minute
LDS API: 3000 requests/minute
Import API:
Cached requests (answered by our CDN) do not count towards this rate limit.
CARTO APIs will send a 429 HTTP response if the API request is over this limit.
Routing: Get routing geometries for different methods of transportation
Tokens API: 300 requests/minute
Connections API: 100 requests/minute
