Mock sample for your project: Asana API

Apptigent PowerTools Developer Edition is a powerful suite of API endpoints for custom applications running on any stack. Manipulate text, modify collections, format dates and times, convert currency, perform advanced mathematical calculations, shorten URL's, encode strings, convert text to speech, translate content into multiple languages, process images, and more. PowerTools is the ultimate developer toolkit.

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 a similarity key used to match with other similar company name data, including for purposes of deduplication, fuzzy matching, or merging of datasets. A much higher match rate will be achieved by matching on the algorithmically generated similarity key rather than the data itself.

Apicurio Registry is a datastore for standard event schemas and API designs. Apicurio Registry enables developers to manage and share the structure of their data using a REST interface. For example, client applications can dynamically push or pull the latest updates to or from the registry without needing to redeploy. Apicurio Registry also enables developers to create rules that govern how registry content can evolve over time. For example, this includes rules for content validation and version compatibility.
The Apicurio Registry REST API enables client applications to manage the artifacts in the registry. This API provides create, read, update, and delete operations for schema and API artifacts, rules, versions, and metadata.
The supported artifact types include:
Apache Avro schema
AsyncAPI specification
Google protocol buffers
GraphQL schema
JSON Schema
Kafka Connect schema
OpenAPI specification
Web Services Description Language
XML Schema Definition
Important: The Apicurio Registry REST API is available from https://MY-REGISTRY-URL/apis/registry/v2 by default. Therefore you must prefix all API operation paths with ../apis/registry/v2 in this case. For example: ../apis/registry/v2/ids/globalIds/{globalId}.

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.

Render Javascript driven pages, while we internally manage Headless Chrome and proxies for you.
Build a custom web scraper with our Visual point-and-click toolkit.
Scrape the most popular Search engines result pages (SERP).
Convert web pages to PDF and capture screenshots.
Authentication
Dataflow Kit API require you to sign up for an API key in order to use the API.
The API key can be found in the DFK Dashboard after free registration.
Pass a secret API Key to all API requests to the server as the api_key query parameter.

Sandbox API

The CircleCI API is a RESTful, fully-featured API that allows you to do almost anything in CircleCI.
You can access all information and trigger all actions.
The only thing we don’t provide access to is billing functions, which must be done from the CircleCI web UI.
