✨ Features

🚢 Ships with clients for the following APIs:

OpenAI:

• Chat Completions (nimbro_api.openai.ChatCompletions)
• Embeddings (nimbro_api.openai.Embeddings)
• Images (nimbro_api.openai.Images)
• Speech (nimbro_api.openai.Speech)
• Transcriptions (nimbro_api.openai.Transcriptions)
• Translations (nimbro_api.openai.Translations)

NimbRo Vision Servers:

• Describe Anything Model (nimbro_api.nimbro_vision_servers.Dam)
• Florence-2 (nimbro_api.nimbro_vision_servers.Florence2)
• Kosmos-2 (nimbro_api.nimbro_vision_servers.Kosmos2)
• MM-Grounding-DINO and LLMDet (nimbro_api.nimbro_vision_servers.MmGroundingDino)
• Segment Anything Model 2 real-time (nimbro_api.nimbro_vision_servers.Sam2Realtime)

Miscellaneous:

• No-as-a-Service (nimbro_api.misc.No)
• VLM-GIST (nimbro_api.misc.VlmGist)

🪧 All clients feature:

• Standardized interfaces
• Sensible default settings
• Monitoring of operation success
• Configurable retry behavior and timeouts
• Extensive documentation, logging, and tests

🪧 In addition, some clients feature:

• Response caching
• Response healing
• Batching of large requests
• API generalization across providers

⚙️ Global settings and utilities are exposed at the package level.

🛠️ Custom clients can be implemented using the nimbro_api.Client and nimbro_api.ClientBase classes.

🚀 Quick Start

Install this package:

pip install nimbro-api

Set the API key for the provider you want to use (e.g. OPENROUTER_API_KEY, OPENAI_API_KEY, VLLM_API_KEY):

export OPENROUTER_API_KEY='supersecretkey'

Create and use a ChatCompletions client:

import nimbro_api
# nimbro_api.set_api_key(name="OPENROUTER_API_KEY", key="supersecretkey") # alternatively, set API key here
client = nimbro_api.openai.ChatCompletions(endpoint="OpenRouter", model="google/gemini-3-flash-preview")
success, message, response = client.prompt(text="Tell me a joke!")
