You can find Vellum's complete API docs at docs.vellum.ai.

Installation

pip install --upgrade vellum-ai

Usage

import vellum
from vellum.client import Vellum


client = Vellum(api_key="YOUR_API_KEY")

result = client.generate(
    deployment_name="my-deployment",
    requests=[
        vellum.GenerateRequest(
            input_values={"question": "Can I get a refund?"})]
    )

print(result.text)

Async Client

import vellum
from vellum.client import AsyncVellum

raven = AsyncVellum(api_key="YOUR_API_KEY")

async def generate() -> str:
  result = client.generate(
    deployment_name="my-deployment",
    requests=[
        vellum.GenerateRequest(
            input_values={"question": "Can I get a refund?"})]
    )
  
  return result.text

Uploading documents

Documents can be uploaded to Vellum via either the UI or this API. Once uploaded and indexed, Vellum's Search allows you to perform semantic searches against them.

from vellum.client import Vellum

client = Vellum(api_key="YOUR_API_KEY")

with open("/path/to/your/file.txt", "rb") as file:
    result = client.documents.upload(
        # File to upload
        contents=file,
        # Document label
        label="Human-friendly label for your document",
        # The names of indexes that you'd like this document to be added to.
        add_to_index_names=["<your-index-name>"],
        # Optionally include a unique ID from your system to this document later.
        #   Useful if you want to perform updates later
        external_id="<your-index-name>",
        # Optionally include keywords to associate with the document that can be used in hybrid search
        keywords=[],
    )

print(result)

Beta status

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning the package version to a specific version in your pyproject.toml file. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

Contributing

While we value open-source contributions to this SDK, this library is generated programmatically. Additions made directly to this library would have to be moved over to our generation code, otherwise they would be overwritten upon the next generated release. Feel free to open a PR as a proof of concept, but know that we will not be able to merge it as-is. We suggest opening an issue first to discuss with us!

On the other hand, contributions to the README are always very welcome!
