Spreads/totals line arb — GET /v1/arb/lines

Line-matched arbitrage on spreads and totals: backs the two opposing sides at complementary lines across books. Returns the best complementary pair per event/market with a guaranteed-profit (is_arb) flag; is_middle marks overlapping lines where both sides can win.

Requires X-API-Key 3 credits

Request

curl 'https://api.puntersedge.online/v1/arb/lines' \
  -H 'X-API-Key: YOUR_KEY'

Parameters

Name	In	Type	Required	Description
`sport_key`	query	string	no	Filter by sport e.g. afl, nrl
`maxAgeMinutes`	query	integer	no	Exclude bookmaker markets older than this many minutes. Same bound and default as /v1/sports/{sport_key}/odds, so an arb can never be built on a price that endpoint refuses to show.
`min_profit_pct`	query	number	no	Min guaranteed profit % (0 = also show the best line comparison when not an arb)
