Each market counts once, however many leagues carry it. Other markets are the provider's own market labels that we have not matched to our market names yet. The extra book and league labels come straight from the provider and are not matched to our book and league names yet. These labels still count in the totals. The league index is the provider's own list of the leagues each book covers, with a market count per league. It names no markets, so a book there counts as carried in that league, and its counts are not in the market totals.
Live odds: yes, per the provider's docs.
A book or league that is missing here did not show up in the provider's catalog or in the events we sampled. It can still exist.
What Owls Insight Is
Owls Insight is a sports betting data API that bundles odds, player props, betting splits, live scores, and a historical closing-line archive into one feed. It covers US sportsbooks, offshore books, Las Vegas locals (Circa, Westgate, Wynn, South Point, Station Casinos), and prediction-market exchanges (Kalshi, Polymarket, Novig, ProphetX). REST and WebSocket delivery, with a free dashboard that includes a positive-EV scanner.
Two things set the coverage apart. First, it carries Pinnacle and bet365 player props, which are the two books that most aggregators struggle to deliver at the prop level. Second, the Las Vegas locals are in the feed. If your model prices against Circa or Westgate lines, you usually need a specialized source for those. Owls Insight puts them alongside the mainstream US books in one normalized schema.
Coverage and Features
Sports coverage spans the major US leagues (NBA, NFL, NHL, MLB, NCAAB, NCAAF, WNBA), international soccer, tennis, MMA, esports (CS2, Valorant, League of Legends, Dota 2), and a tail of niche sports: boxing, cricket, darts, handball, rugby, snooker, table tennis, volleyball, and aussie rules.
The sportsbook list includes:
- US majors: FanDuel, DraftKings, BetMGM, Caesars, Hard Rock.
- Sharp books: Pinnacle and PS3838, with a dedicated sharp realtime feed.
- Offshore: 1xBet, BetOnline, MyBookie.
- Las Vegas locals: Circa Sports, Westgate, Wynn, South Point, Station Casinos.
- Exchanges and prediction markets: Kalshi, Polymarket, Novig, ProphetX.
Market types include moneylines, spreads, totals, futures, same-game parlays, and player props. The historical archive stores closing lines for backtesting, and live scores are available on every paid plan, including cricket, darts, and table tennis. For more context on why closing lines matter, see our historical odds guide.
Owls Insight Pricing and the Free Tier
Five tiers, all published on the site:
- Free ($0/mo): account access and the EV scanner dashboard. No API request quota, so you can explore the dashboard and the data model before you commit.
- Bench ($9.99/mo): 10,000 requests/month, all books, raw per-book feeds (v2) over REST, with the WebSocket add-on available.
- Rookie ($24.99/mo): 75,000 requests/month. Adds player props and betting splits.
- MVP ($49.99/mo): 300,000 requests/month. Adds the sharp realtime feed from Pinnacle/PS3838 and the historical closing-line archive. Comes with a 3-day free trial.
- Hall of Fame ($200/mo): unlimited requests, WebSocket connection included. Enterprise-grade.
WebSocket access is included on Hall of Fame and available as a paid add-on for any other paid plan. The pricing undercuts most competitors at every tier. At $9.99 you get all books over REST, which is cheaper than many providers' entry plans. The MVP tier at $49.99 unlocks the historical archive and sharp feed, features that some APIs reserve for enterprise contracts.
The EV Scanner Dashboard
Owls Insight ships a browser-based EV scanner alongside the API. It ranks every selection by expected value across Kalshi, Polymarket, and the major sportsbooks, normalized to one board and sorted by edge. No code required to use it.
The dashboard also includes a Kalshi-settled simulated trader with a transparent record of every bet, settled on real Kalshi outcomes. That simulated track record gives you a way to evaluate the scanner's output before you feed it into your own tooling. For developers, the scanner is a quick sanity check: if the dashboard shows an edge on a selection, you can pull the same odds through the API and verify the math yourself.
Getting an API Key
Create an account on the Owls Insight register page with an email, Google or Discord. That link carries our referral, so a monthly plan gets 10% off for its first 3 months at checkout. One thing to know up front: a free account can sign in, but it can't create an API key. The key comes with a plan, from Bench at $9.99 a month, and you manage it in the dashboard (checked November 2026).
Want to test before you pay? The monthly MVP plan has a 3-day trial. It needs a card at checkout, it's one trial per person and per card, and cancelling inside the 3 days ends API access with no charge. Annual plans don't include it. REST calls send the key as Authorization: Bearer <key>, and the docs rule out x-api-key. The WebSocket takes it as apiKey in the Socket.IO query string.
A First Request in Python
This pulls the merged NBA board from GET /api/v1/nba/odds on https://api.owlsinsight.com. It's the same route and the same Bearer header that our own probe uses (checked November 2026), plus the docs' books filter to trim the answer to Pinnacle and FanDuel. Bench and every plan above it can call it.
import os
import requests
key = os.environ["OWLS_INSIGHT_API_KEY"]
resp = requests.get(
"https://api.owlsinsight.com/api/v1/nba/odds",
headers={"Authorization": f"Bearer {key}"},
params={"books": "pinnacle,fanduel"},
timeout=15,
)
resp.raise_for_status()
body = resp.json()
print("board age (s):", body["meta"]["freshness"]["ageSeconds"])
for book, events in body["data"].items():
for ev in events[:3]:
print(book, ev["away_team"], "at", ev["home_team"], ev["commence_time"])The data object maps each book to its own list of events with home_team, away_team, commence_time and a bookmakers array of markets and prices. meta.freshness.ageSeconds gives the board's age, and meta.freshness.stale flips to true past 90 seconds. Swap nba for nfl, soccer or cs2 and the shape stays the same.
Rate Limits, Docs and SDKs
On top of the monthly quota, each plan caps a key per minute and in flight: Bench allows 20 requests a minute with 1 running at a time, Rookie 120 with 5, MVP 400 with 15 and Hall of Fame 1,000 with 20 (checked November 2026). The monthly count resets on your billing date, not the 1st. Responses carry X-RateLimit-Remaining-Minute and X-RateLimit-Remaining-Month, and a 429 adds Retry-After in seconds. Go over the concurrency cap and the 429 comes at once, with no queue. WebSocket messages don't count against the REST quota.
Four official SDKs cover TypeScript (owls-insight-ts on npm), Python (owls-insight on PyPI), Go and Kotlin or Java on Maven Central. The docs publish an OpenAPI spec at /openapi.json, the changelog lives at /updates, and a status page tracks uptime. Owls also hosts an MCP server at api.owlsinsight.com/mcp (Streamable HTTP, Bearer key) for any paid plan; the docs call it beta. For help, email support@owlsinsight.com or ask in the Owls Insight Discord.
Who Owls Insight Is For
The combination of sharp books, Vegas locals, prediction markets, and props in one feed points at a few clear use cases:
- +EV and CLV bettors who price against Pinnacle and need closing lines to grade their bets afterward.
- Props modelers who want Pinnacle and bet365 props alongside DraftKings and FanDuel in the same schema.
- Vegas-aware tools that need Circa, Westgate, or South Point lines. These books rarely appear in mainstream odds APIs.
- Prediction-market traders comparing Kalshi and Polymarket pricing against traditional sportsbook odds.
- Budget-conscious developers who want sharp odds and historical data without a $200+/month starting price.
The sportsbook count is focused rather than exhaustive, covering the books that matter for sharp pricing rather than every regional soft book. If you need 300+ books in one call, Owls Insight pairs well with a broad aggregator from the sports odds API directory: the aggregator brings the breadth, and Owls Insight brings the sharp books, Vegas locals and props.
How It Compares
Most odds APIs pick a lane: broad aggregation (hundreds of books, mainstream markets) or narrow specialization (one sharp source, low latency). Owls Insight sits between the two. The book count is modest compared to the 300+ aggregators, but the book selection is deliberate: Pinnacle, bet365, the US majors, Vegas locals, and exchanges. That mix covers the books that quantitative bettors actually reference.
The pricing is aggressive. At $49.99/month you get sharp realtime, historical closing lines, and 300K requests, a feature set that costs $200+ at several competitors. The trade-off is that the sportsbook list is curated rather than exhaustive, and the product is younger than some established providers. The team is active in the SportsAPIs Discord and ships updates frequently, which is a good sign for a newer entrant but also means the API surface is still evolving.
Verdict
Owls Insight fills a gap that the market left open: sharp odds, Vegas locals, prediction markets, and player props in one API at a price that does not assume you have a funded operation. The free EV scanner shows moneylines with no login, and the 3-day MVP trial lets you test the API at no charge if you cancel in time. The historical archive on the MVP plan at $49.99 is hard to match at that price point.
Check the free EV scanner, then start the 3-day MVP trial and pull a few endpoints to see if the book and sport coverage fits your model. If Pinnacle props and Vegas locals are in your requirements, this is one of the few feeds that delivers both.
Our Take
What stood out when we vetted Owls Insight for the directory:
- 39 books in one feed, including Pinnacle, bet365, DraftKings, FanDuel and BetMGM, with main lines across all of them
- WebSocket push for instant line moves, not polling
- Pinnacle and bet365 player props, the two books most providers cannot deliver
- Priced as a cheaper alternative to the established odds APIs, with a free tier to try first
Clean main lines across all books and the WebSocket does what it claims. Good props coverage on some very hard to find books. The team ships fast and is one of the most active in the Discord.
