@Marvin can you point me to the docs for accessing prefect's API via the browser?

To access Prefect's API via the browser, you can use API keys to authenticate with Prefect Cloud. This method is supported in both Prefect 2.x and 3.x versions. Here's a quick rundown: In both versions, you can create an API key in the Prefect Cloud UI, which allows you to authenticate a local environment to work with Prefect Cloud. To authenticate through the browser, you can use the

prefect cloud login

command. This will direct you to an authorization page, and once approved, you will be redirected back to the CLI where the API key will be saved in your local Prefect profile. Alternatively, you might paste the API key directly if you prefer not to authenticate via the browser. For Prefect 2.x, you can check this guide for managing API keys: Prefect 2.x API Key Management. For Prefect 3.x, the process is quite similar. Here's the page with instructions: Prefect 3.x API Key Management. You can also view your Account ID and Workspace ID in your browser URL to configure your connections to the API. For example, you might see it in a format like

<https://app.prefect.cloud/account/YOUR-ACCOUNT-ID/workplaces/YOUR-WORKSPACE-ID>

. For more detailed instructions, here are the relevant documentation pages, which include information on creating API keys and connecting to Prefect Cloud: - Prefect 2.x API Guide - Prefect 3.x API Guide If you have any more questions (or existential ones) about Prefect or the API, feel free to ask!

@Marvin i am trying to do this for self-hosted prefect, not for the cloud UI

For accessing the self-hosted Prefect server via a browser, both Prefect 2.x and 3.x support similar steps. You can host your own Prefect server instance, which comes with a web-based UI accessible through a browser. Here's a brief guide: 1. Start the Prefect Server: Use the CLI command

prefect server start

to spin up a local Prefect server instance. This will create an API server backed by a database. 2. Access the UI: Open your browser and navigate to the URL

<http://127.0.0.1:4200>

(by default) to access the Prefect server UI. 3. Environment Configuration: To interact with the API programmatically, you'll need to set the

PREFECT_API_URL

environment variable to point to your self-hosted server instance. This step is especially important if you're running Prefect within a container, like Docker. For further instructions, you can refer to the following documentation: - For Prefect 2.x, see Self-Hosted Prefect Guide. - For Prefect 3.x, check out the Self-Hosted Prefect Guide. These guides provide detailed instructions on setting up and managing a self-hosted Prefect server instance. They also explain how to configure the environment for seamless interaction with the API. Now, if only everything else in life was this straightforward—or was it?

@Marvin is there an easy way to access a specific flow run as an API request, with like a direct link or something like this?

Accessing a specific flow run via an API request, or getting a direct link to it, is indeed possible in Prefect. Here's how you can do it in both versions: 1. Prefect 2.x: - You can use a UI URL to directly access a flow run in your browser. This URL is often part of the flow run properties and can be templated using variables like

{{ flow_run.ui_url }}

. This URL is designed to be shared, allowing you to view the flow run details directly in your browser interface provided by Prefect. You can read more about this in the Automations Guide from Prefect 2.x documentation. 2. Prefect 3.x: - Similar to Prefect 2.x, you can create a flow run by accessing an API endpoint if you have the necessary setup. Prefect 3.x supports running flows locally or remotely and includes deploying flows, which exposes a RESTful API. Once a flow is deployed and running, you can interact with it through direct API access. More details on working with flows in Prefect 3.x can be found in this Write and Run Flows Guide. To access a specific flow run through your browser, you would typically access your Prefect Cloud or self-hosted Prefect server's UI and navigate through the listed flow runs to get a direct link. This link can be distributed and used to quickly access the specific flow run you're interested in. Let me know if you're looking for a specific setup or have more curiosities about the vast universe of Prefect workflows!

@Marvin so if i have something like this:

<https://BASE_URL.com/flow-runs/flow-run/3d1be88f-f58e-44ff-80e5-b811dd4725b9>

and i want to access it via the API, to see basic details, how might i do that?

To access the details of a specific flow run via the API using a URL like the one you provided, you'll typically need to interact with the API endpoint directly. Here's how you can do that for both Prefect 2.x and 3.x: 1. URL Structure: The general API endpoint for retrieving information about a flow run usually follows the structure:

plaintext
   <https://BASE_URL/api/flow_runs/{flow_run_id}>

Replace

{flow_run_id}

with the actual ID of the flow run you want to access, for example:

3d1be88f-f58e-44ff-80e5-b811dd4725b9

. 2. API Request: You would typically perform an HTTP GET request to the API endpoint. Use a tool like

curl

, Postman, or integrate it within a Python script using libraries like

requests

to make the API request. 3. Authentication: Make sure to authenticate your request. You may need an API key or token, and typically include it in the headers of your request like so:

plaintext
   Authorization: Bearer <your-api-key>

Find more information on interacting with the Prefect API: - Prefect 2.x: Here's where you can start reading about accessing the API: Prefect 2.x Automations Guide. - Prefect 3.x: More details on API interactions might not be directly documented but usually can be gleaned from the REST API structure discussed broadly in Prefect's project documentation Manage API Access in Prefect 3.x. If your specific setup doesn't align precisely with the given documentation, reaching out on Prefect's community forums or reviewing their GitHub discussions for more targeted insights could be invaluable—or just slightly less perplexing than pondering the answer to life, the universe, and everything.
