Chromia Console API with Swagger UI

Chromia Console Client

A Python client library for interacting with the Chromia Console Vector Database API. This client provides a simple and type-safe way to manage vector collections, perform similarity searches, and work with embeddings.

Installation

pip install de_console_client

Quick Start

from de_console_client import Configuration, ApiClient, ChromiaVectorDBApi
from de_console_client.models import VectorCollection

# 1. Configure the client
configuration = Configuration(
    host='https://chromia-console.chromia.dev',
    brid='YOUR_BLOCKCHAIN_RID',
    network='mainnet',  # or 'testnet' or 'https://node0.testnet.chromia.com'
    chromia_api_key='YOUR_API_KEY'
)

# 2. Create the API client
with ApiClient(configuration) as api_client:
    client = ChromiaVectorDBApi(api_client)
    
    # 3. Create a collection
    collection = VectorCollection(
        name='my_first_collection',
        dimension=384,  # Vector dimension for embeddings
        index='hnsw_cosine',
        query_max_vector=10,
        store_batch_size=100
    )
    client.add_collection(collection)
    
    # 4. Store some text as vector embeddings (batch operation)
    client.create_vector_embedding_batch(
        'my_first_collection',
        [
            'The quick brown fox jumps over the lazy dog',
            'Chromia is a relational blockchain platform',
            'Vector databases enable semantic search'
        ]
    )
    
    # 5. Search using text query
    search_results = client.search_objects(
        collection='my_first_collection',
        body='tell me about Chromia',
        max_vectors=2       # return top 2 results
    )
    
    print('Search results:', search_results.payloads)

Configuration

The Configuration object accepts the following parameters:

Parameter	Type	Required	Description
host	str	Yes	Base URL of the Chromia Console API
brid	str	Yes	Blockchain RID (Identifier)
network	str	Yes	Network name (e.g., 'mainnet', 'testnet') or url
chromia_api_key	str	Yes	API key for authentication

Environment Variables

You can use environment variables to configure the client:

import os
from de_console_client import Configuration

configuration = Configuration(
    host=os.getenv('CHROMIA_CONSOLE_BASE_PATH'),
    brid=os.getenv('BRID'),
    network=os.getenv('NETWORK', 'mainnet'),
    chromia_api_key=os.getenv('API_KEY')
)

Response Types

TransactionResultBody

All write operations return a TransactionResultBody:

{
    'tx_rid': str,         # Transaction ID
    'status': str,         # 'confirmed', 'waiting', 'pending', or 'rejected'
    'reject_reason': str   # Only present if status is 'rejected' (optional)
}

GetClosestResponse

Search operations return a GetClosestResponse:

{
    'payloads': [str]      # Array of matched payloads
}

PayloadDistance

Distance-aware searches return List[PayloadDistance]:

{
    'text': str,           # Payload text
    'distance': float      # Distance from query vector
}

Error Handling

The client uses standard Python exceptions. Handle errors using try-except:

from de_console_client import ApiClient, ChromiaVectorDBApi, Configuration
from de_console_client.rest import ApiException

configuration = Configuration(
    host='https://chromia-console.chromia.dev',
    brid='YOUR_BLOCKCHAIN_RID',
    network='mainnet',
    chromia_api_key='YOUR_API_KEY'
)

try:
    with ApiClient(configuration) as api_client:
        client = ChromiaVectorDBApi(api_client)
        response = client.create_vector(
            'my_collection',
            vector_request
        )
        print('Success:', response)
except ApiException as e:
    # API-specific error occurred
    print(f'API Exception: {e.status}')
    print(f'Reason: {e.reason}')
    print(f'Body: {e.body}')
except Exception as e:
    # General error occurred
    print(f'Error: {str(e)}')
