Lambda_Zero

Lambda_Zero is a unified platform for scientific machine learning, providing the newest Nexa models for predictions in biology (protein structure), astrophysics (stellar properties), and material science (material properties). Access these models via a simple REST API, with results returned in JSON format including predictions and confidence scores (0-100%).

Quick Start

Prerequisites

• Python 3.9+
• An API key (still in dev coming soon)
• requests library (pip install requests)

Example: Protein Structure Prediction

Predict the secondary structure of a protein sequence:

import requests

response = requests.post(
    "https://api.scimlhub.com/v1/bio/predict",
    headers={"X-API-Key": "your_api_key"},
    json={"sequence": "MAKQVKL"}
)

result = response.json()
print(result)
# Output: {"prediction": "H", "confidence": 80.56}

Example: Stellar Property Prediction

Estimate a star's mass:

response = requests.post(
    "https://api.scimlhub.com/v1/astro/predict",
    headers={"X-API-Key": "your_api_key"},
    json={
        "temp": 5778,  # Kelvin
        "luminosity": 1.0,  # Solar luminosity
        "metallicity": 0.0  # [Fe/H]
    }
)

result = response.json()
print(f"Stellar Mass: {result['prediction']} Solar masses")
print(f"Confidence: {result['confidence']}%")
# Output: {"prediction": 1.0, "confidence": 97.49}

Example: Material Property Prediction

Predict a material's band gap:

response = requests.post(
    "https://api.scimlhub.com/v1/materials/predict",
    headers={"X-API-Key": "your_api_key"},
    json={"structure": "POSCAR data string"}
)

result = response.json()
print(f"Band Gap: {result['prediction']} eV")
print(f"Confidence: {result['confidence']}%")
# Output: {"prediction": 2.5, "confidence": 98.5}
