Odds API for Parlay Builders

A multi and same-game-multi builder API: pull every market as a leg (props, alt lines, game markets), normalise via oddID, and compute combined odds.

A multi (parlay) builder needs every market a user could add as a leg, priced by every book, in one normalised shape. SockOdds returns 1,192 markets — game lines, props, alt lines — under one oddID grammar with decimal prices ready to multiply, plus the same-game-multi lanes the Australian books run.

Why build your multi builder on SockOdds

Every leg in one shape. Lines, totals, head to head, props and alternates share the oddID grammar.
Decimal prices, ready to multiply. byBookmaker[*].decimal — no conversion step.
Same-game-multi lanes. betfocus__sgm_only, mintbet__sgm_only, dabble__sgm_only and picklebet__sgm_only price SGM legs separately.
Per-leg deeplinks. links.bookmakers and links.betslip.
Fair prices to sanity-check the multi. fairOdds per leg on Base and above.

How a multi builder works with our data

Pull the legs a user can add

One events call per league; every market in odds is a candidate leg.

Compute the combined price

Multiply the chosen legs' decimal at the chosen book; see the parlay calculator example.

Handle same-game multis correctly

Legs from the same event are correlated; use the SGM lanes' prices where a book runs them rather than multiplying independent prices.

Deeplink each leg

Send the user to the book with the event link.

Frequently asked questions

What is a parlay API?

A feed of every market that can be a leg, normalised so a builder can combine them. Australians call it a multi.

Can I build same-game multis?

Yes — use the SGM lanes' prices where a book runs them; independent multiplication over-prices correlated legs.

How do I calculate combined odds?

Multiply each leg's decimal price.

What markets can be legs?

Any market in the event's odds object.

Can I deeplink a multi to a bookmaker?

To the event; bet-slip pre-fill depends on the book.

Which sports are supported?

All 12.
