Mock sample for your project: Snyk API

This API provides area code information for a given telephone area code.

User Recommendation Engine and Chat Network

This API provides validation information for email addresses to aid in deliverability. Syntax, existence of mail servers, and other tests are run to ensure delivery. Additional demographics are provided for the email address as well, including identifying generic, vulgar, education, government, or other entity type email addresses.

The Postman API allows you to programmatically access data stored in Postman account with ease.
The easiest way to get started with the API is to click the fork button to fork this collection to your own workspace and use Postman to send requests.
Overview
You need a valid API Key to send requests to the API endpoints. You can get your key from the integrations dashboard.
The API has an access rate limit applied to it.
The Postman API will only respond to secured communication done over HTTPS. HTTP requests will be sent a 301 redirect to corresponding HTTPS resources.
Response to every request is sent in JSON format. In case the API request results in an error, it is represented by an "error": {} key in the JSON response.
The request method (verb) determines the nature of action you intend to perform. A request made using the GET method implies that you want to fetch something from Postman, and POST implies you want to save something new to Postman.
The API calls will respond with appropriate HTTP status codes for all requests. Within Postman Client, when a response is received, the status code is highlighted and is accompanied by a help text that indicates the possible meaning of the response code. A 200 OK indicates all went well, while 4XX or 5XX response codes indicate an error from the requesting client or our API servers respectively.
Individual resources in your Postman Account is accessible using its unique id (uid). The uid is a simple concatenation of the resource owner's user-id and the resource-id. For example, a collection's uid is {{ownerid}}-{{collectionid}}.
Authentication
An API Key is required to be sent as part of every request to the Postman API, in the form of an X-Api-Key request header.
> If you do not have an API Key, you can easily generate one by heading over to the Postman Integrations Dashboard.
An API Key tells our API server that the request it received came from you. Everything that you have access to in Postman is accessible with an API Key that is generated by you.
For ease of use inside Postman, you could store your API key in an environment variable called postmanapikey and this Collection will automatically use it to make API calls.
API Key related error response
If an API Key is missing, malformed, or invalid, you will receive a 401 Unauthorised response code and the following JSON response:
Support
For help regarding accessing the Postman API, feel free to discuss it in our Discourse Community. You can also drop in a line at [email protected].
In the event you receive a 503 response from our servers, it implies that we have hit an unexpected spike in API access traffic and would usually be operational within the next 5 minutes. If the outage persists, or your receive any other form of 5XX error, kindly let us know.
Terms of Use
For information on API terms of use and privacy, refer to our terms at http://postman.com/legal/terms/ and our privacy policy at https://www.postman.com/legal/privacy-policy/.
API Reference

Airbyte Configuration API
https://airbyte.io.
This API is a collection of HTTP RPC-style methods. While it is not a REST API, those familiar with REST should find the conventions of this API recognizable.
Here are some conventions that this API follows:
All endpoints are http POST methods.
All endpoints accept data via application/json request bodies. The API does not accept any data via query params.
The naming convention for endpoints is: localhost:8000/{VERSION}/{METHODFAMILY}/{METHODNAME} e.g. localhost:8000/v1/connections/create.
For all update methods, the whole object must be passed in, even the fields that did not change.
Change Management:
The major version of the API endpoint can be determined / specified in the URL localhost:8080/v1/connections/create
Minor version bumps will be invisible to the end user. The user cannot specify minor versions in requests.
All backwards incompatible changes will happen in major version bumps. We will not make backwards incompatible changes in minor version bumps. Examples of non-breaking changes (includes but not limited to...):
Adding fields to request or response bodies.
Adding new HTTP endpoints.

Introduction
Api2Pdf is a powerful PDF generation API with no rate limits or file size constraints. Api2Pdf runs on AWS Lambda, a serverless architecture powered by Amazon to scale to millions of requests while being up to 90% cheaper than alternatives. Supports wkhtmltopdf, Headless Chrome, LibreOffice, and PDF Merge. You can also generate barcodes with ZXING (Zebra Crossing).
SDKs & Client Libraries
We've made a number of open source libraries available for the API
Python: https://github.com/api2pdf/api2pdf.python
.NET: https://github.com/api2pdf/api2pdf.dotnet
Nodejs: https://github.com/api2pdf/api2pdf.node
PHP: https://github.com/Api2Pdf/api2pdf.php
Ruby: (Coming soon)
Authorization
Create an account at portal.api2pdf.com to get an API key.
Authorize your API calls
GET requests, include apikey=YOUR-API-KEY as a query string parameter
POST requests, add Authorization to your header.
For more advanced usage and settings, see the API specification below.

This API provides a similarity key used to match with other similar full name data when data fields are parsed into first name and last name components, including for purposes of deduplication, fuzzy matching, or merging of datasets. A much higher match rate will be achieved by matching on the similarity key rather than the data itself. This API is for full name data where first and last name are in separate fields. Use the Full Name Similarity Key API for first and last name data that are in the same field.

This API provides area code information for a given telephone number.
