Mock sample for your project: COVID19 Stats API

The Geographic API extends the Semantic API, using a linked data approach to enhance location concepts used in The New York Times' controlled vocabulary and data resources which combine them with the GeoNames database, an authoritative and free to use database of global geographical places, names and features.

VersionEye is a cross-platform search engine for free/libre/open source software libraries.

Get detailed data on over 120,000 schools and 18,500 districts in the U.S.

Driving License (DL) and Vehicle Registration Certificate (RC) of the State, as available on Parivahan Sewa (http://parivahan.co.in/) of Ministry of Road Transport and Highways, are available on DigiLocker. Citizens can pull these documents into their DigiLocker accounts.

This API represents address cleaning, correction, completion, geocoding, reverse geocoding, and proximity resources for intersection addresses, physical addresses and their occupants in British Columbia. Please read our data collection notice.
Please note that you may experience issues when submitting requests to the delivery or test environment if using this OpenAPI specification in other API console viewers.
Developer API keys are unique and can be acquired with a GitHub account. Production government applications may use organization API keys acquired by contacting DataBC. API keys are further described in the Developer guide.

Enforcement and Compliance History Online (ECHO) is a tool developed and maintained by EPA's Office of Enforcement and Compliance Assurance for public use. ECHO provides integrated compliance and enforcement information for over 1 million regulated facilities nationwide.
DFR Rest Services provide multiple service endpoints, to retrieve detailed facility location, enforcement, compliance monitoring, and pollutant information for any single facility. See the Detailed Facility Report (DFR) Help Page (https://echo.epa.gov/help/reports/detailed-facility-report-help) for additional information on the DFR. Additionally, a Data Dictionary (https://echo.epa.gov/help/reports/dfr-data-dictionary) is also available.
There is one primary service end point, get_dfr, that provides all available DFR data. All other service end points that are exposed, will return data on a single section of the DFR.

Enforcement and Compliance History Online (ECHO) is a tool developed and maintained by EPA's Office of Enforcement and Compliance Assurance for public use.
ECHO provides integrated compliance and enforcement information for over 1 million regulated facilities nationwide.
EFF Rest Services provides the data for ECHO's Effluent Charts, a set of dynamic charts and tables of permitted effluent limits, releases, and violations over time for Clean Water Act (CWA) wastewater discharge permits issued under the National Pollutant Discharge Elimination System (NPDES).
See Effluent Charts Help (https://echo.epa.gov/help/reports/effluent-charts-help) for additional information.
\
The are 3 service end points for Effluent Charts: getsummarychart, geteffluentchart, and downloadeffluentchart.
\
1) Use getsummarychart to retrieve a summary matrix of effluent parameters by effluent outfall and an overall violation status for a provided NPDES Permit and date range.
2) Use geteffluentchart to retrieve detailed Discharge Limit, DMR and NPDES Violation information for a provided NPDES Permit, date range, effluent parameter, or outfall.
3) Use downloadeffluentchart to generate a Comma Separated Value (CSV) file of the detailed data provided with get_effluent chart, for a provided NPDES Permit, date range, effluent parameter, or outfall.

You can use the CORE API to access the
resources harvested and enriched by CORE. If you encounter any problems with the API, please report them to us.
Overview
The API is organised by resource type. The resources are articles,
journals and repositories and are represented using JSON data format. Furthermore,
each resource has a list of methods. The API also provides two global methods for accessing all resources at once.
Response format
Response for each query contains two fields: status and data.
In case of an error status, the data field is empty. The data field contains a single object
in case the request is for a specific identifier (e.g. CORE ID, CORE repository ID, etc.), or
contains a list of objects, for example for search queries. In case of batch requests, the response
is an array of objects, each of which contains its own status and data fields.
For search queries the response contains an additional field totalHits, which is the
total number of items which match the search criteria.
Search query syntax
Complex search queries can be used in all of the API search methods.
The query can be a simple string or it can be built using terms and operators described in Elasticsearch
documentation.
The usable field names are title, description, fullText,
authors, publisher, repositories.id, repositories.name,
doi, oai, identifiers (which is a list of article identifiers including OAI, URL, etc.), language.name
and year. Some example queries:
title:psychology and language.name:English
repositories.id:86 AND year:2014
identifiers:"oai:aura.abdn.ac.uk:2164/3837" OR identifiers:"oai:aura.abdn.ac.uk:2164/3843"
doi:"10.1186/1471-2458-6-309"
Retrieving the latest Articles
You can retrieve the harvested items since specific dates using the following queries:
repositoryDocument.metadataUpdated:>2017-02-10
repositoryDocument.metadataUpdated:>2017-03-01 AND repositoryDocument.metadataUpdated:
Sort order
For search queries, the results are ordered by relevance score. For batch
requests, the results are retrieved in the order of the requests.
Parameters
The API methods allow different parameters to be passed. Additionally, there is an API key parameter which is common to all API methods. For all API methods
the API key can be provided either as a query parameter or in the request header. If the API key
is not provided, the API will return HTTP 401 error. You can register for an API key here.
