# Spreads/totals line arb

`GET /v1/arb/lines`

## Request

- Base URL: `https://api.puntersedge.online`
- URL: `https://api.puntersedge.online/v1/arb/lines`
- Auth: API key in header `X-API-Key`

Cost: 3 credits. 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.

## Query parameters

- `sport_key` string: Filter by sport e.g. afl, nrl
- `maxAgeMinutes` integer: 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` number: Min guaranteed profit % (0 = also show the best line comparison when not an arb)

- `X-API-Key` string
- `X-RapidAPI-Proxy-Secret` string
