U.S. EPA Enforcement and Compliance History Online (ECHO) - Safe Drinking Water 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. SDW Rest Services provides multiple service endpoints, each with specific capabilities, to search and retrieve data on public water systems regulated under the Safe Drinking Water Act (SDWA). The returned results reflect data drawn from EPA's Federal Safe Drinking Water Information System (SDWIS) database. \ The get_systems, get_qid, and get_download end points are meant to be used together. \ The recommended use scenario for get_systems, get_qid, and get_downoad is: \ <b>1)</b> Use get_systems 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 water system results. <b>3)</b> Use get_download, with the returned QID, to generate a Comma Separated Value (CSV) file of water system 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>

D&D 5e API

Open Data

# Introduction Welcome to the dnd5eapi, the Dungeons & Dragons 5th Edition API! This documentation should help you familiarize yourself with the resources available and how to consume them with HTTP requests. Read through the getting started section before you dive in. Most of your problems should be solved just by reading through it. ## Getting Started Let's make our first API request to the D&D 5th Edition API! Open up a terminal and use [curl](http://curl.haxx.se/) or [httpie](http://httpie.org/) to make an API request for a resource. You can also scroll through the definitions below and send requests directly from the endpoint documentation! For example, if you paste and run this `curl` command: ```bash curl -X GET "https://www.dnd5eapi.co/api/ability-scores/cha" -H "Accept: application/json" ``` We should see a result containing details about the Charisma ability score: ```bash { "index": "cha", "name": "CHA", "full_name": "Charisma", "desc": [ "Charisma measures your ability to interact effectively with others. It includes such factors as confidence and eloquence, and it can represent a charming or commanding personality.", "A Charisma check might arise when you try to influence or entertain others, when you try to make an impression or tell a convincing lie, or when you are navigating a tricky social situation. The Deception, Intimidation, Performance, and Persuasion skills reflect aptitude in certain kinds of Charisma checks." ], "skills": [ { "name": "Deception", "index": "deception", "url": "/api/skills/deception" }, { "name": "Intimidation", "index": "intimidation", "url": "/api/skills/intimidation" }, { "name": "Performance", "index": "performance", "url": "/api/skills/performance" }, { "name": "Persuasion", "index": "persuasion", "url": "/api/skills/persuasion" } ], "url": "/api/ability-scores/cha" } ``` ## Authentication The dnd5eapi is a completely open API. No authentication is required to query and get data. This also means that we've limited what you can do to just `GET`-ing the data. If you find a mistake in the data, feel free to [message us](https://discord.gg/TQuYTv7). ## GraphQL This API supports [GraphQL](https://graphql.org/). The GraphQL URL for this API is `https://www.dnd5eapi.co/graphql`. Most of your questions regarding the GraphQL schema can be answered by querying the endpoint with the Apollo sandbox explorer. ## Schemas Definitions of all schemas will be accessible in a future update. Two of the most common schemas are described here. ### `APIReference` Represents a minimal representation of a resource. The detailed representation of the referenced resource can be retrieved by making a request to the referenced `URL`. ``` APIReference { index string name string url string } ``` <hr> ### `DC` Represents a difficulty check. ``` DC { dc_type APIReference dc_value number success_type "none" | "half" | "other" } ``` <hr> ### `Damage` Represents damage. ``` Damage { damage_type APIReference damage_dice string } ``` <hr> ### `Choice` Represents a choice made by a player. Commonly seen related to decisions made during character creation or combat (e.g.: the description of the cleric class, under **Proficiencies**, states "Skills: Choose two from History, Insight, Medicine, Persuasion, and Religion" [[SRD p15]](https://media.wizards.com/2016/downloads/DND/SRD-OGL_V5.1.pdf#page=15)) ``` Choice { desc string choose number type string from OptionSet } ``` <hr> ### `OptionSet` The OptionSet structure provides the options to be chosen from, or sufficient data to fetch and interpret the options. All OptionSets have an `option_set_type` attribute that indicates the structure of the object that contains the options. The possible values are `options_array`, `equipment_category`, and `reference_list`. Other attributes on the OptionSet depend on the value of this attribute. - `options_array` - `options` (array): An array of Option objects. Each item in the array represents an option that can be chosen. - `equipmen
