Quick start

from talyxion import Talyxion

client = Talyxion(api_key="tk_...")  # or set TALYXION_API_KEY

# Daily trading signals
page = client.signals.list(date="2026-04-27", asset_class="crypto", min_conviction=0.7)
for sig in page.items:
    print(sig.ticker, sig.side, sig.conviction)

# Ticker snapshot
info = client.ticker("VIC").info()
print(info.latest_signal.entry_price, info.stats.win_rate)

# Rates terminal
snapshot = client.rates.snapshot()
ten_year = client.rates.series("DGS10")

# Run an alpha simulation and stream progress
for event in client.stream.sim_progress(task_id):
    print(event.progress, event.message)
    if event.status in ("done", "error"):
        break

Authentication

Pass your API key via constructor or the TALYXION_API_KEY env var. Keys are issued from the Talyxion dashboard and require an api or institutional subscription tier.
