Python

Native PyO3 bindings over the Rust core. Construct a Shazam from a JSON spec, then drive it with command(json) -> json — index first, then match.

pip install wickra-shazam

import json
from wickra_shazam import Shazam

spec = json.dumps({
    "features": [{"kind": "indicator", "name": "Rsi", "params": [14]},
                 {"kind": "price", "field": "close"}],
    "window": 10,
    "normalize": "z_score",
    "metric": "cosine",
})

shazam = Shazam(spec)
shazam.command(json.dumps({"cmd": "index", "history": history}))
report = json.loads(shazam.command(json.dumps({"cmd": "match", "current": current, "k": 5})))
for m in report["matches"]:
    print(m["ts"], m["similarity"])
