alphainfo 1.0.3

Python client for alphainfo.io — Structural Regime Detection API

alphainfo

Python client for the alphainfo Structural Intelligence API.

Detect structural regime changes in time series — biomedical signals, financial markets, energy grids, seismic data, IoT sensors, and more. No model training required.

from alphainfo import AlphaInfo

client = AlphaInfo(api_key="ai_your_key")
result = client.analyze(signal=ecg_data, sampling_rate=360.0, domain="biomedical")

print(result.confidence_band)   # 'stable', 'transition', or 'unstable'
print(result.structural_score)  # 0.0 to 1.0
print(result.analysis_id)       # UUID for audit trail

Installation

pip install alphainfo

Requires Python 3.8+. Only dependency: httpx.

Quick Start

1. Get your API key

Sign up at alphainfo.io/register — free tier includes 50 analyses/month.

2. Analyze a signal

from alphainfo import AlphaInfo

client = AlphaInfo(api_key="ai_your_key")

# Any time series: ECG, market prices, sensor readings, power grid...
result = client.analyze(
    signal=[1.2, 1.3, 1.1, 2.8, 3.1, 3.0, ...],
    sampling_rate=250.0,
    domain="biomedical",
)

if result.change_detected:
    print(f"Regime change detected! Band: {result.confidence_band}")
    print(f"Structural score: {result.structural_score:.3f}")
    print(f"Audit ID: {result.analysis_id}")

3. Analyze market data

# The API fetches market data automatically
market = client.analyze_market("AAPL", interval="1d")
print(f"AAPL regime: {market.confidence_band}")
print(f"Score: {market.structural_score:.3f}")

4. Batch analysis

# Analyze up to 100 signals in one call
batch = client.analyze_batch(
    signals=[signal_1, signal_2, signal_3],
    sampling_rate=1000.0,
    domain="sensors",
)

for item in batch.results:
    if item.success:
        print(f"Signal {item.index}: {item.confidence_band} ({item.structural_score:.3f})")
    else:
        print(f"Signal {item.index}: error — {item.error}")

5. Multi-channel (vector) analysis

# Multi-lead ECG, multi-axis accelerometer, etc.
vector = client.analyze_vector(
    channels={
        "lead_I": ecg_lead_1,
        "lead_II": ecg_lead_2,
        "lead_III": ecg_lead_3,
    },
    sampling_rate=360.0,
    domain="biomedical",
)

print(f"Aggregated score: {vector.structural_score:.3f}")
for name, ch in vector.channels.items():
    print(f"  {name}: {ch.confidence_band}")

6. Audit trail

# Replay any past analysis
replay = client.audit_replay("550e8400-e29b-41d4-a716-446655440000")
print(f"Original score: {replay.output['structural_score']}")

# List recent analyses
history = client.audit_list(limit=10)
for entry in history:
    print(f"{entry.analysis_id} — {entry.structural_score}")

Async Support

from alphainfo import AsyncAlphaInfo

async with AsyncAlphaInfo(api_key="ai_your_key") as client:
    result = await client.analyze(signal=data, sampling_rate=250.0)
    market = await client.analyze_market("BTC-USD")

All methods available on AlphaInfo are also available on AsyncAlphaInfo.

Error Handling

from alphainfo import AlphaInfo, AuthError, RateLimitError, ValidationError

client = AlphaInfo(api_key="ai_your_key")

try:
    result = client.analyze(signal=data, sampling_rate=250.0)
except AuthError:
    print("Invalid API key")
except RateLimitError as e:
    print(f"Rate limited. Retry after {e.retry_after}s")
except ValidationError as e:
    print(f"Invalid input: {e.message}")

Exception hierarchy:

Exception	HTTP Code	When
AuthError	401	Invalid or missing API key
ValidationError	400, 413	Bad input or signal too large
RateLimitError	429	Quota or concurrency limit exceeded
NotFoundError	404	Analysis ID not found (audit)
APIError	5xx	Server error
TimeoutError	—	Request timed out after retries
NetworkError	—	Connection failed

All inherit from AlphaInfoError.

Configuration

client = AlphaInfo(
    api_key="ai_your_key",
    base_url="https://alphainfo.io",  # default
    timeout=30.0,                      # seconds (default)
    max_retries=3,                     # automatic retry on transient errors
)

The client automatically retries on:

• Network timeouts and connection errors
• HTTP 429 (rate limits) — respects Retry-After header
• HTTP 5xx (server errors)

Non-retryable errors (401, 400, 404) are raised immediately.

Rate Limit Info

result = client.analyze(signal=data, sampling_rate=250.0)
info = client.rate_limit_info
if info:
    print(f"Remaining: {info.remaining}/{info.limit}")
