Get Pinnacle closing lines via API for CLV

Answer: call GET /v1/closing/{eventId} (or /v1/closing?date=YYYY-MM-DD) with your API key, read the market's no-vig fair price at close, then CLV = price_taken / closing_fair − 1. Closing-line history is on Builder (€99/mo) and above. Full tracker: CLV guide.

Compute CLV in Python#

import os, requests

KEY = os.environ["PINNFEED_KEY"]
BASE = "https://pinnfeed.io/v1"
event_id, market_key, side, taken = 1640229582, "s;0;m", "home", 2.10

r = requests.get(f"{BASE}/closing/{event_id}", headers={"x-api-key": KEY}, timeout=10)
r.raise_for_status()
m = next(x["market"] for x in r.json()["markets"] if x["market"]["key"] == market_key)
fair = next(o["fair"] for o in m["outcomes"] if o["name"] == side)
clv = taken / fair - 1
print(f"took {taken}, closed fair {fair:.3f}, CLV {clv:+.2%}")

Questions people ask#

Should I use raw close or fair close?#

Use fair (no-vig). Beating a raw price that still contains Pinnacle's margin overstates edge. PinnFeed exposes both.

When is the close captured?#

When the event starts: the last prematch price per market, with capturedAt.

Is this educational content for adults?#

Yes (18+). CLV is a statistical concept, not a tip or a guaranteed edge.
