FRC Events

Open Data

<html><head></head><body><h1 id="overview">Overview</h1> <p><em>FIRST</em>/FMS FRC Events API is a service to return relevant information about the <em>FIRST</em> Robotics Competition (FRC). Information is made available from events operating around the world.</p> <p>For FRC, information is made available by the Field Management System (FMS) server operating at each event site. The FMS will attempt to sync all data from the event to "the cloud" as long as internet is available at the venue. If internet is unavailable, or "goes down" during the event, the FMS will automatically sync all data from the time the system was offline as soon as the connection is restored. The API will provide data as soon as it has synced, and we do not add any artificial delays. If you are receiving "stale" data, it may be because of connectivity problems at the venue. We recommend you try again later, and post on the FIRST FMS TeamForge site if the problem persists. <em>(Note: FMS does not sync while a match is running, so data that has to do with a particular match should become available once the score has been revealed to the audience at the event.)</em></p> <h3 id="migration-and-program-notes">Migration and Program Notes:</h3> <p>Pay close attention to the addresses for calling the various endpoints- as well as the notes regarding endpoints with multiple possible responses (i.e. score details and rankings).</p> <h1 id="documentation-notes">Documentation Notes</h1> <p>All times are listed in the local time to the event venue. HTTP-date values will show their timezone.</p> <p>If you specify a parameter, but no value for that parameter, it will be ignored. For example, if you request <strong>URL?teamNumber=</strong> the <strong>teamNumber</strong> parameter would be ignored.</p> <p>We will continue to support the current version of the API plus one version older. Old APIs are depricated once a version "two times newer" is available, at minimum 6 months. For example, version 2.0 and 1.0 are supported right now, but 1.0 will not be supported once 2.1 (or 3.0) is available. Versions may also be retired earlier with prior notice here in the documentation.</p> <p>The full host address of the API is needed in all calls. The version number is required in each call in order to ensure your requests are made (and responses are returned) in the formats you anticipate. The version number for this documentation is found on the top of the page, in the title. If you call this version number, the API responses will match the formats listed below.</p> <p>All of the APIs are capable of accepting the <strong>Accept</strong> HTTP header with either <strong>application/xml</strong> or <strong>application/json</strong> based on the desired return type. Any API call that results in an <strong>HTTP Status Code</strong> other than <strong>200 (OK)</strong> will only be shown here as an <strong>application/json</strong> response to save space, but the content is the same regardless of the request type. All response will have a <strong>Content-Length</strong> and <strong>Date</strong> response header, but those are not shown in the documentaiton.</p> <p>For all APIs that accept a query string in addition to the URI base, the order of parameters do not matter, but the name shown in the documentation must match exactly, as does the associated value format as described in details.</p> <p>For response codes that are not <strong>HTTP 200 (OK)</strong>, the documentation will show a body message that represents a possible response value. While the "title" of the <strong>HTTP Status Code</strong> will match those shown in the response codes documentation section exactly, the body of the response will be a more detailed explanation of why that status code is being returned and may not always be exactly as shown in the examples.</p> <p>None of the APIs will show possible return here in the documentation of <strong>HTTP 401 (Unauthorized)</strong>, but that code applies to all APIs a

Climate FieldView Platform APIs

Open Data

**Last Modified**: Wed Jan 4 12:47:29 UTC 2023 All endpoints are only accessible via HTTPS. * All API endpoints are located at `https://platform.climate.com` (e.g. `https://platform.climate.com/v4/fields`). * The authorization token endpoint is located at `https://api.climate.com/api/oauth/token`. ## Troubleshooting `X-Http-Request-Id` response header will be returned on every call, successful or not. If you experience an issue with our api and need to contact technical support, please supply the value of the `X-Http-Request-Id` header along with an approximate time of when the request was made. ## Request Limits When you’re onboarded to Climate’s API platform, your `x-api-key` is assigned a custom usage plan. Usage plans are unique to each partner and have the following key attributes: 1. Throttling information * burstLimit: Maximum rate limit over a period ranging from 1 second to a few seconds * rateLimit: A steady-state rate limit 2. Quota information * Limit: The maximum number of requests that can be made in a given month When the request rate threshold is exceeded, a `429` response code is returned. Optionally, the [`Retry-After`](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.37) header may be returned: Following are examples of rate limit errors: 1. Rate limit exceeded: <br>HTTP/1.1 429 <br>Content-Type: application/json <br>Content-Length: 32 {"message":"Too Many Requests"} 2. Quota exhausted: <br>HTTP/1.1 429 <br>Content-Type: application/json <br>Content-Length: 29 {"message":"Limit Exceeded"} ## Pagination Pagination is performed via headers. Any request which returns a `"results"` array may be paginated. The following figure shows how query results are laid out with X-Limit=4 and no filter applied. <img style="width:70%;height:auto;" src="https://s3-us-west-2.amazonaws.com/climate-com/images/svg_upload_tests/paging.png"> * If there are no results, a response code of `304` will be returned. * If the response is the last set of results, a response code of `200` or `206` will be returned. * If there are more results, a response code of `206` will be returned. * If `X-Next-Token` is provided in the request headers but the token has expired, a response code of `409` will be returned. This is only applicable for some endpoints; see specific endpoint documentation below. #### X-Limit The page size can be controlled with the `X-Limit` header. Valid values are `1-100` and defaults to `100`. #### X-Next-Token If the results are paginated, a response header of `X-Next-Token` will be returned. Use the associated value in the subsequent request (via the `X-Next-Token` request header) to retrieve the next page. The following sequence diagram shows how to use `X-Next-Token` to fetch all the records. <img src="https://s3-us-west-2.amazonaws.com/climate-com/images/svg_upload_tests/x-next-token.svg"> ## Chunked Uploads Uploads larger than `5MiB` (`5242880 bytes`) must be done in `5MiB` chunks (with the exception of the final chunk). Each chunk request MUST contain a `Content-Range` header specifying the portion of the upload, and a `Content-Type` header specifying binary content type (`application/octet-stream`). Range uploads must be contiguous. The maximum upload size is capped at `500MiB` (`524288000 bytes`). ## Chunked Downloads Downloads larger than `5MiB` (`5242880 bytes`) must be done in `1-5MiB` chunks (with the exception of the final chunk, which may be less than `1MiB`). Each chunk request MUST contain a `Range` header specifying the requested portion of the download, and an `Accept` header specifying binary and json content types (`application/octet-stream,application/json`) or all content types (`*/*`). ## Drivers If you need drivers to process agronomic data, download the ADAPT plugin below. We only support the plugin in the Windows environment, minimum is Windows 7 SP1. For asPlanted, asHarvested and asApplied data: * [ADAPT Plugin](https://dev.fieldview.com/drivers/ClimateADAPTPlugin_latest.exe) <br>R

City of Surrey Traffic Loop Count API.

Open Data

This API provides locations of City of Surrey traffic loops and the corresponding traffic loop counts in 15 minute intervals. While the counts are broken up by 15 minute intervals, the data is currently loaded only once per day. We are hoping to increase this frequency to at least once every hour. The LOOP_ID field is common to both datasets and can be used to cross-reference them.

U.S. EPA Enforcement and Compliance History Online (ECHO) - Resource Conservation and Recovery Act

Open Data

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. RCRA Rest Services provides multiple service endpoints, each with specific capabilities, to search and retrieve data on hazardous waste handlers/facilities regulated under the Resource Conservation and Recovery Act (RCRA). The returned results reflect data drawn from EPA's RCRAInfo 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. \ Additional ECHO Resources: <a href="https://echo.epa.gov/tools/web-services">Web Services</a>, <a href="https://echo.epa.gov/resources/echo-data/about-the-data">About ECHO's Data</a>, <a href="https://echo.epa.gov/tools/data-downloads">Data Downloads</a>
