lgtm, ship it

Docs and AI bundle integration need to be added first.

Hmm, super weird 🤔

And where is that $location-aiplatform.googleapi.com/... coming from?
Docs say it's just aiplatform as subdomain:

See https://console.cloud.google.com/vertex-ai/publishers/google/model-garden/gemini-2.5-flash-lite

@chr-hertel
It is actually weird considering I can see both the URLs in the documentation, one that you pointed out and another that I used. For instance:

1. If you head over to Api quickstart, you will see the URL that is used in the code. API_ENDPOINT basically refers to {REGION}-aiplatform.googleapis.com. I used the latter because it is easier for library users to set the location instead of the entire base URL.
2. In the api reference, which is what I mostly used, admittedly (or surprisingly), the page for the generateContent endpoint doesn't show the URL to access the api, but the one for Embeddings does. And it is exactly what I used. Please go to this for more details.
3. There are also other pages that have variations of the same URL.

P.S. I made a change now to remove the location from the start of the request URL for both text and embedding generation after verifying it works. It matches the URL that you referenced, but the location is still there in the middle.

and also with that endpoint change the examples vertexai/token-metadata.php and vertexai/toolcall.php raise errors for me:

Btw, code-wise we're good here, thanks for that! I just want to be able to run all examples locally to make sure all integrations are still working. And I'm not super deep into google cloud. is there something special that you configured in vertex? global region? any models or endpoints in action here?

@chr-hertel
All the examples work for me as they did earlier:

Changes I made:

Vertex AI:

1. Followed the instructions as mentioned here
2. Set the env var GOOGLE_CLOUD_PROJECT to the ID of the newly created project on GCloud, created specifically for this purpose (though an existing project should work well too with the right set of permissions/access, I think), and set the env var GOOGLE_CLOUD_LOCATION to us-central1.

Locally:

1. Initialized the gcloud CLI as mentioned in the aforementioned linked page.
2. Have been using platform/vendor/autoload.php directly inside the examples/bootstrap.php file right from the start.

@chr-hertel
Could you let me know if you were able to run the examples or if something still needs to be done here?

Code-wise all looks good to me - mostly depends on me to find the issue of testing. Not gonna happen this week tho, sorry.

@chr-hertel
Any update on this?

Could you let me know if you managed to give it a shot?

@chr-hertel is currently AFK for some days.

Oh ok.
Thanks for the update.

one thing i learned lately, that it fails due to the region - that was a good pointer of yours - so you could reproduce with switching to global - not sure how to deal with that tho - add a hint in docs?

@chr-hertel
Sure, why not!
I added a dedicated doc for Vertex AI that has this information, besides other information.

Thank you @junaidbinfarooq.
