Bottom line: OddsPapi is a strong odds-only esports feed with a genuine free tier. EsportsOdds bundles CS2 match, player and team data with a single de-vigged line in one payload, self-serve at $99/month.
The short version
OddsPapi is a genuinely good developer-first odds API: a free tier, wide bookmaker coverage, clean docs, and both a REST and a WebSocket feed. If what you need is raw odds to build a comparison, arbitrage or model-input tool, it is a strong, low-friction choice.
The difference is scope. OddsPapi is odds only: by its own description it ships no player or team statistics. EsportsOdds is a CS2 data-and-line bundle: match, player, team and tournament data plus a single de-vigged market line, from one self-serve key at a flat $99/month. If you want the number and the data behind it without stitching two vendors together, that is the reason to look here.
Who looks for an OddsPapi alternative
- Builders who need stats, not just prices (a media table, a fantasy feed, a match preview) where odds alone aren't enough.
- CS2-focused teams who want depth in one title rather than a broad multi-sport odds feed.
- Products that want one clean, neutral line to display or model against, rather than raw per-book prices to reconcile themselves.

Where OddsPapi genuinely wins
A fair comparison leads with what the other product does well, and OddsPapi has real strengths.
A free tier. OddsPapi offers a free plan with no card required, and it is unusually generous: wide bookmaker coverage, and even historical odds that many providers paywall. As a developer on-ramp that is genuinely good, and EsportsOdds does not match it there: our only free route is a 7-day trial that requires a card up front and carries an allowance of 1,000 requests across the whole trial. If evaluating without a card matters to you, that difference is real and it favours them. One thing to read before you build on it: OddsPapi's terms state you "may not resell, repackage, or redistribute [its] data as a standalone product." That is a standard restriction rather than an unusual one, but if redistribution is the point of your product, check it against your plans early.
Bookmaker breadth. OddsPapi advertises coverage across a large number of bookmakers (300+ by its own count), among the widest published catalogues of any developer-accessible odds API. If your product's whole purpose is comparing many books' prices, that breadth is a real advantage EsportsOdds does not try to match.
Developer experience. Simple key-based auth, JSON, versioned endpoints, honest docs, and both a REST API and a WebSocket feed on paid tiers. It is a clean, low-friction product.
EsportsOdds is not trying to out-breadth OddsPapi on raw odds, and it is not cheaper than free. It is a different product for a different job.
The bundle, not just a feed
OddsPapi prices lines across many books and hands them to you. If you also need the data behind those lines (the match, the roster, the tournament, the player stats), OddsPapi doesn't ship it, and points you to a separate stats vendor to add on.
EsportsOdds returns both from one key: a CS2 match's teams, players and tournament and its market line. For a media tool or a fantasy product that is one integration instead of two, and one bill instead of two, with the line already joined to the same IDs as the data around it.
Where OddsPapi's product is built around per-book prices, EsportsOdds serves a single de-vigged market line — a market-implied win probability combined from multiple bookmakers and exchanges, with the margin removed and no individual book named or priced. That is a deliberate design and compliance choice. Both approaches are legitimate: if you want raw prices from many named books, OddsPapi is built for it; if you want one neutral number plus the CS2 data around it, EsportsOdds is.
The de-vig is verifiable rather than a marketing phrase. Across every live market the two sides of a line sum to exactly 100%, because the margin is already out:
// GET /v1/cs2/odds - one row per outcome, illustrative prices; the sum is the point
{ "outcome_key": "team_a", "price": 1.80, "source": "eo_market" } // 1 / 1.80 = 55.6%
{ "outcome_key": "team_b", "price": 2.25, "source": "eo_market" } // 1 / 2.25 = 44.4%
// 55.6% + 44.4% = 100.0%
The maths, and why removing the margin matters, is worked through in de-vigging fair odds.
OddsPapi is odds only: great for raw, multi-book prices, self-serve, with a strong free tier. EsportsOdds bundles CS2 match, player and team data with a single de-vigged market line — one key, one clean number, no per-book prices, $99/month flat.
Pricing and access
Both are self-serve with no sales call. OddsPapi leads with a free tier and then moves to usage-based paid plans, with the WebSocket feed on paid (its pricing is a usage calculator). EsportsOdds is a single flat $99/month for 20,000 requests, every endpoint included, with a 7-day trial (1,000 requests) to start.
The honest framing: if a free tier is your deciding factor, OddsPapi wins that line. EsportsOdds competes on the bundle and CS2 depth, not on being the cheapest raw-odds source.
Who should choose OddsPapi
Choose OddsPapi if you want broad, self-serve odds, especially many bookmakers' prices for comparison, arbitrage or closing-line work, and you don't need structured stats alongside them. Its free tier and book breadth make it a strong fit for that job.
Who should choose EsportsOdds
Choose EsportsOdds if you are building on CS2 and want the data and a market line in one place: match, player, team and tournament data plus a de-vigged line, self-serve, at a flat $99/month. It is one integration where an odds-only feed plus a stats vendor would be two.
Frequently asked questions
Does OddsPapi include CS2 stats or just odds?
Odds only. OddsPapi states it ships no player or team statistics. EsportsOdds bundles CS2 match, player, team and tournament data with its market line in one key.
Does EsportsOdds show odds from many bookmakers?
No, by design. EsportsOdds serves a single de-vigged market line (a market-implied win probability with the margin removed), and never publishes per-book prices or bookmaker names. If you specifically need many named books' prices, an odds-comparison feed like OddsPapi is the right tool.
Is EsportsOdds cheaper than OddsPapi?
Not on raw price: OddsPapi has a free tier and EsportsOdds does not (it has a 7-day trial with 1,000 requests, then $99/month flat). EsportsOdds competes on the CS2 data-and-line bundle.
Can I use EsportsOdds and OddsPapi together?
Yes. Some teams use EsportsOdds for CS2 match, player and team data plus a clean line, and an odds-comparison feed like OddsPapi where they specifically need many books' raw prices. If you only need one, choose by whether your product shows the data around the line (EsportsOdds) or just compares prices (OddsPapi).
