Grade bets against the close (CLV)
propline_grade_clvHobby+ endpoint. Grades PLACED bets against their closing lines. Closing line value is the only durable proxy for whether a bettor has edge: did the price they took beat the number the market settled on? Send the bets and each comes back with its closing price, the de-vigged closing fair probability, CLV, and — once the game settles — the graded resolution and actual stat value, plus a portfolio summary. Stateless: nothing is stored. TWO CLV numbers are returned deliberately. clv_pct is price-vs-price: familiar and quotable, but VIG-BLIND, so it flatters a bet taken on the juicy side of a wide market. ev_vs_close_pct scores the price against the DE-VIGGED close and is the honest one — report that one when the user asks whether they got value. The de-vig anchors to the SHARPEST book quoting that line at close (fair_source), not the book they bet at, because de-vigging their own book always returns a negative number (they paid its hold). Bets whose event has not started carry closing_is_final=false, are counted in summary.pending, and are EXCLUDED from the summary averages: before kickoff the 'closing' price is just the latest price, so CLV is ~0 by construction — do not present those as results. Matching is fail-closed: a bet that cannot be pinned to exactly one stored outcome returns matched=false with an unmatched_reason instead of a wrong match, so surface those rows rather than silently dropping them. Max 500 bets per request. Free tier returns structure with every number nulled.

| Name | Required | Description | Default |
|---|---|---|---|
| bets | Yes | Placed bets to grade. selection is the subject: player name for a prop, team name for a game line. | |
| devig | No | How the closing anchor's vig is removed before closing_fair_prob / ev_vs_close_pct. 'multiplicative' (default) or 'shin' (loads the overround onto the longshot). Same vocabulary as propline_get_event_ev; echoed as devig_method. |
