Mock sample for your project: Coronavirus API

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.
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 getfacilities, getmap, getqid, and getdownload end points are meant to be used together, while the enhanced getfacilityinfo end point is self contained.
The getfacilityinfo 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 getfacilities, getqid, getmap, and getdownoad is:
1) Use getfacilities to validate passed query parameters, obtain summary statistics and to obtain a queryid (QID). QIDs are time sensitive and will be valid for approximately 30 minutes.
2) Use get_qid, with the returned QID, to paginate through arrays of facility results.
3) 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.
4) 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.

An API which retrieves Members data.

The Veteran Confirmation API allows you to confirm Veteran status for a given person. This can be useful for offering Veterans discounts or other benefits.
The API will only return “Confirmed” or “Not Confirmed”.
Quickstart Guide
1. Get Access Credentials
Get started by filling out the form on the Apply for VA Lighthouse Developer Access page.
After submitting a request, you will receive your credentials for using the API in the Development environment, which allows you to try it out with mock data before moving to the Production environment.
2. Test the API
In the endpoint documentation below, we've provided a curl command builder for trying out the API before implementation with your app.
Use Test User attributes to populate the request body.
3. Build your app
The base URI for the Veteran Confirmation API in the Sandbox environment is:
https://sandbox-api.va.gov/services/veteran_confirmation/v0
In this environment, use attributes from the list of Test Users. Only Test Users can return a "confirmed" response.
Check out some of our sample apps. Please visit our VA Lighthouse Support portal should you need further assistance.
4. Show us a demo and get access to the Production environment
After building your app, we ask that you give us a demo before we set you up with production credentials. Please see the Path to Production page for more details.
Authorization
This API requires an API key in combination with identifiable information for the person being confirmed listed below. API requests are authorized through a symmetric API token provided in an HTTP header with name apikey. Including more information has a better chance of making a match and returning a Confirmed status.
Required information:
First Name
Last Name
Date of Birth
Social Security Number
Optional information:
Middle Name
Gender
Reference
Sandbox vs. Production Data
APIs accessed via the Sandbox environment are using the same underlying logic as VA’s production APIs; only the underlying data store is different.
Master Veteran Index (MVI)
The Master Veteran Index confirms a user's identity. In Production, several factors are considered to confirm identity. These include: a user’s first name, last name, date of birth and Social Security number. The MVI is mocked in the Sandbox environment. In this environment, the only factor used to confirm identity is the Social Security number.
Rate Limiting
We implemented basic rate limiting of 60 requests per minute. If you exceed this quota, your request will return a 429 status code. You may petition for increased rate limits by emailing and requests will be decided on a case by case basis.

The Benefits Intake API allows authorized third-party systems used by Veteran Service Organizations (VSOs), agencies, and Veterans to digitally submit VA benefits claim documents directly to the Veterans Benefits Administration's (VBA) claims intake process. This API handles documents related to the following benefit claim types:
Compensation
Pension/Survivors Benefits
Education
Fiduciary
Insurance
Veteran Readiness & Employment (VRE)
Board of Veteran Appeals (BVA)
This API also provides submission status updates until documents are successfully established for VBA claim processing, eliminating the need for users to switch between systems to manually check whether documents have been successfully uploaded.
Background
This API provides a secure, efficient, and tracked alternative to mail or fax for VA benefit claim document submissions. Documents are uploaded directly to the VBA so they can be processed as quickly as possible.
Technical overview
The Benefits Intake API first provides an upload location and unique submission identifier, and then accepts a payload consisting of a document in PDF format, zero or more optional attachments in PDF format, and some JSON metadata.
The metadata describes the document and attachments, and identifies the person for whom it is being submitted. This payload is encoded as binary multipart/form-data (not base64). The unique identifier supplied with the payload can subsequently be used to request the processing status of the uploaded document package.
To avoid errors and processing delays, API consumers are encouraged to validate the zipcode,fileNumber, veteranFirstName, veteranLastName and businessLine fields before submission according to their description in the DocumentUploadMetadata model and use the 'businessLine' attribute for the most efficient processing. Additionally, please ensure no PDF user or owner passwords are used in submitted PDFs.
Attachment & file size limits
There is no limit on the number of files a payload can contain, but size limits do apply.
Uploaded documents cannot be larger than 21" x 21"
The entire payload cannot exceed 5 GB
No single file in a payload can exceed 100 MB
Date of receipt
The date that documents are successfully submitted through the Benefits Intake API is used as the official VA date of receipt. However, note that until a document status of received, processing, success, or vbms is returned, a client cannot consider the document received by VA.
A status of received means that the document package has been transmitted, but may not be validated. Any errors with the document package, such as unreadable PDFs or a Veteran not found, will cause the status to change to error.
If the document status is error, VA has not received the submission and cannot honor the submission date as the date of receipt.
Authentication and Authorization
API requests are authorized through a symmetric API token, provided in an HTTP header with name 'apikey'. Request an API key.
Testing in the sandbox environment
In the sandbox environment, the final status of a submission is received and submissions do not actually progress to the central mail repository or VBMS.
Progress beyond the received status can be simulated for testing. We allow passing in a Status-Override header on the /uploads/{id} endpoint so that you can change the status of your submission to simulate the various scenarios.
The available statuses are pending, uploaded, received, processing, success, vbms, and error. The meaning of the various statuses is listed below in Models under DocumentUploadStatusAttributes.
Test data
We use mock test data in the sandbox environment. Data is not sent upstream and it is not necessary to align submitted test data with any other systems' data.
Upload operation
Allows a client to upload a multi-part document package (form + attachments + metadata).
Client Request: POST https://sandbox-api.va.gov/services/vba_documents/v1/
No request body or parameters required
Service Response: A JSON API object with the following attributes:
guid: An identifier used for subsequent status requests
location: A URL to which the actual document package payload can be submitted in the next step. The URL is specific to this upload request, and should not be re-used for subsequent uploads. The URL is valid for 900 seconds (15 minutes) from the time of this response. If the location is not used within 15 minutes, the GUID will expire. Once expired, status checks on the GUID will return a status of expired.
Note: If, after you've submitted a document, the status hasn't changed to uploaded before 15 minutes has elapsed, we recommend retrying the upload in order to make sure the document properly reaches our servers. If the upload continues to fail, try encoding the payload as Base64 (See below).
Client Request: PUT to the location URL returned in Step 2.
Request body should be encoded as binary multipart/form-data (base64 also available - see details below), equivalent to that generated by an HTML form submission or using “curl -F…”. The format is described in more detail below.
No apikey authorization header is required for this request, as authorization is embedded in the signed location URL.
Service Response: The HTTP status indicates whether the upload was successful.
Additionally, the response includes an ETag header containing an MD5 hash of the submitted payload. This can be compared to the submitted payload to ensure data integrity of the upload.
Status caching
Due to current system limitations, data for the /uploads/report endpoint is cached for one hour.
A request to the /uploads/{id} endpoint will return a real-time status for that GUID, and update its status in /uploads/report.
The updated_at field indicates the last time the status for a given GUID was updated.
Optional Base64 encoding
Base64 is an encoding scheme that converts binary data into text format, so that encoded textual data can be easily transported over networks uncorrupted and without data loss.
Base64 can be used to encode binary multipart/form-data it in its entirety. Note that the whole payload must be encoded, not individual parts/attachments.
After encoding your payload, you'll be required to preface your base64 string with data:multipart/form-data;base64, in order to allow our system to distinguish the file type. Your final string payload would look something like data:multipart/form-data;base64,(encryption string)== and close with the standard == marker. Note that the multipart boundaries i.e. -----WebKitFormBoundaryVfOwzCyvug0JmWYo and ending ------WebKitFormBoundaryVfOwzCyvug0JmWYo- must also be included.

API v3 targets v2 functionality with a few minor additions. The API is accessible via https://api.thetvdb.com and provides the following REST endpoints in JSON format.
How to use this API documentation
You may browse the API routes without authentication, but if you wish to send requests to the API and see response data, then you must authenticate.
Obtain a JWT token by POSTing to the /login route in the Authentication section with your API key and credentials.
Paste the JWT token from the response into the "JWT Token" field at the top of the page and click the 'Add Token' button.
You will now be able to use the remaining routes to send requests to the API and get a response.
Language Selection
Language selection is done via the Accept-Language header. At the moment, you may only pass one language abbreviation in the header at a time. Valid language abbreviations can be found at the /languages route..
Authentication
Authentication to use the API is similar to the How-to section above. Users must POST to the /login route with their API key and credentials in the following format in order to obtain a JWT token.
{"apikey":"APIKEY","username":"USERNAME","userkey":"USERKEY"}
Note that the username and key are ONLY required for the /user routes. The user's key is labled Account Identifier in the account section of the main site.
The token is then used in all subsequent requests by providing it in the Authorization header. The header will look like: Authorization: Bearer . Currently, the token expires after 24 hours. You can GET the /refresh_token route to extend that expiration date.
Versioning
You may request a different version of the API by including an Accept header in your request with the following format: Accept:application/vnd.thetvdb.v$VERSION. This documentation automatically uses the version seen at the top and bottom of the page.
