U.S. EPA Enforcement and Compliance History Online (ECHO) - Clean Air Act
Open DataEnforcement 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. Air Rest Services provides multiple service endpoints, each with specific capabilities, to search and retrieve data on facilities regulated under the Clean Air Act (CAA). The returned results reflect data drawn from EPA's ICIS-Air database. The get_facilities, get_map, get_qid, and get_download end points are meant to be used together, while the enhanced get_facility_info end point is self contained. The get_facility_info end point returns either an array of state, county or zip clusters with summary statistics per cluster or an array of facilities. The recommended use scenario for get_facilities, get_qid, get_map, and get_downoad is: <b>1)</b> Use get_facilities to validate passed query parameters, obtain summary statistics and to obtain a query_id (QID). QIDs are time sensitive and will be valid for approximately 30 minutes. <b>2)</b> Use get_qid, with the returned QID, to paginate through arrays of facility results. <b>3)</b> Use get_map, with the returned QID, to zoom in/out and pan on the clustered and individual facility coordinates that meet the QID query criteria. <b>4)</b> Use get_download, with the returned QID, to generate a Comma Separated Value (CSV) file of facility information that meets the QID query criteria. Use the qcolumns parameter to customize your search results. Use the Metadata service endpoint for a list of available output objects, their Column Ids, and their definitions to help you build your customized output.

setlist.fm API
Media<p> The setlist.fm API has been designed to give you easy access to setlist data in order to build fancy websites and other applications. Before starting to use the API, be sure to ... <ol> <li>... understand how setlist.fm works (the <a href="https://www.setlist.fm/faq">FAQ</a> and the <a href="https://www.setlist.fm/guidelines">Guidelines</a> are a good starting point),</li> <li>... read this documentation carefully and</li> <li>... <a href="https://www.setlist.fm/settings/api">apply for an API key</a> (link for logged in users only) - if you're no registered user yet, then <a href="https://www.setlist.fm/signup">register first</a> (it's free).</li> </ol> </p> <p> If this documentation isn't enough or if you've got other things you'd like to tell us about the API, visit the <a href="https://www.setlist.fm/forum/setlistfm/setlistfm-api">API Forum</a>. </p> <p> Note that the setlist.fm API is, according to the <a href="https://www.setlist.fm/help/api-terms">API terms of service</a>, only free for non-commercial projects. If you're interested in using the API for commercial purposes, <a href="https://www.setlist.fm/contact">contact us</a>. </p> <h2>About this Service</h2> <p> This service provides methods to get both setlists and components of setlists such as artists, cities, countries or venues. </p> <h2>Supported Content Types</h2> <p> The REST service currently supports XML (default) and JSON content. </p> <p> To receive a JSON response, set the <code>Accept</code> <a href="https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1">header</a> to <em>application/json</em>. </p> <h2>Internationalization</h2> <p> <small>(Please note that this is an experimental feature and does not work for all cities!)</small> </p> <p> Most of the featured methods honor the <code>Accept-Language</code> <a href="https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.4">header</a>. This header is used for localizing cities and countries. The default language is English (en), but you can provide any of the languages Spanish (es), French (fr), German (de), Portuguese (pt), Turkish (tr), Italian (it) or Polish (pl). </p> <p> E.g. if you search a setlist for a concert that took place in Vienna and you pass "de" as header, you'll get <em>"Wien, Österreich"</em> instead of <em>"Vienna, Austria"</em>.<br/> This also works if you use a different language than the country's native language. </p> <p> E.g. for a concert in New York, you'll get <em>"Nueva York, Estados Unidos"</em> instead of <em>"New York, United States"</em> if you pass "es" as language. </p> <h2>API Keys</h2> API keys (<a href="https://www.setlist.fm/settings/api">application form</a>) must be included in the request with the <code>x-api-key</code> header. <h2>Version History</h2> <table class="table table-bordered table-versions"> <thead> <tr> <th>Version</th> <th>Docs</th> <th>End of Service</th> </tr> </thead> <tbody> <tr> <td><strong>1.0</strong></td> <td><a href="/docs/1.0">Docs</a></td> <td>-</li> </tr> <tr> <td><strong>0.1</strong></td> <td></td> <td>December 31, 2017</li> </tr> </tbody> </table>
