SharpAPI (from $79 a month), SportsGameOdds (a fairOdds field) and Unabated (its own line on paid tiers) return no-vig prices, checked 15 Nov 2026. novigapi.com returns Novig's fair price, the two-sided mid of an exchange book, on every market, plus a keyless devig tool for any odds you send. (Source: [SharpAPI: pricing](https://sharpapi.io/pricing))

There are two ways to get a fair price: remove the margin from a sportsbook's two prices (devig), or read a market with no built-in margin, such as an exchange mid. The second needs no devig assumptions.

The devig tool below ran on 15 Nov 2026 with -150 / +130 and no key:

## Where novigapi.com falls short

> Our fair price is Novig's book only. A blend of several sharp books, as some feeds offer, is steadier on thin markets.

## Questions

### Which devig method is best?

There is no single best. Multiplicative is the common default; Shin and power push more of the margin onto longshots. /fair-price returns all four.

### Can I devig without a key?

Yes, with the devig tool on the novigapi.com MCP server, or the no-vig calculator page.
