I need a full-stack web application that lets my users build their own wagers in one place, then push those exact bets straight to DraftKings and FanDuel. The flow I have in mind is simple for the bettor but technically involved behind the scenes, so I’m looking for someone who already understands sportsbook APIs, web scraping, or compliant browser automation. Core user experience • Users log in, connect their DraftKings and/or FanDuel accounts (OAuth or secure credential vault—whatever the platforms allow). • On the dashboard they see football, basketball and baseball markets first, with the architecture flexible enough to bolt on additional sports later. • For every market the user drags sliders to set custom odds, spreads or player-prop lines. As the value changes the UI should immediately show what the “real” line/price is on the book so they know how far they’re deviating. • The moment they hit “Place Bet,” the system mirrors that wager on the selected book and returns a confirmation ticket. All funds, KYC and payouts stay with DraftKings/FanDuel; my app never touches cash. Tech expectations • Modern front end (React, Vue or similar) with responsive design. • Back end service that normalises markets from both books, matches the user’s custom line to the nearest available alternate line, and submits the wager. • Robust error handling for edge cases (market moved, bet rejected, user limits, etc.). • Secure storage of any auth tokens and strict logging of bet attempts for compliance. • Clean, well-documented codebase plus a short hand-off session or video explaining deployment. Acceptance criteria 1. User can connect at least one sportsbook account and place a live $0.10 test wager successfully on both DraftKings and FanDuel in staging. 2. Sliders reflect real-time odds for football, basketball and baseball without page refresh. 3. Bet receipt number from the book is displayed back to the user within five seconds or less. 4. Adding a new sport requires only a config file change and no code rewrite. 5. Source code, environment variables template and setup guide are delivered in a private repo. If you’ve already worked with any official DK/FD endpoints or built similar bet-placement tools, that’s a huge plus—please mention it.

What you’re really building isn’t just a betting dashboard—it’s a translation layer between a custom wagering experience and two sportsbooks that each have their own market structures, pricing updates, account restrictions, and bet acceptance rules. The first thing I’d do is validate the account connection path for both DraftKings and FanDuel, because that will determine whether we’re working with supported integrations or compliant browser automation. From there I’d build a normalization service that continuously maps markets, alternate lines, and player props into a single format so the frontend sliders always have a real-time reference point. When a user submits a wager, I’d run a final market verification before placement to handle moved lines, suspended markets, stake limits, and rejected bets gracefully rather than returning vague failures. I’d also make the sport configuration data-driven so adding new leagues later is a config change instead of a backend rewrite. I’ve built automation-heavy PHP and Python systems before where reliability and audit logging mattered more than raw speed, which feels very similar to this use case. One thing I’d want to confirm first: do you already have approved access to any DK/FD endpoints, or should the solution assume browser automation from day one?

Hello, this is a sportsbook orchestration problem more than a standard dashboard build, and the part that matters is the handoff between live market state, account-linked execution, and confirmation under tight latency. The real engineering risk is not the React UI; it is keeping line normalization, market movement handling, and bet placement idempotent when DraftKings or FanDuel shift the underlying market between quote and submit. I usually structure systems like this with a clear separation between market ingestion, odds normalization, execution, and audit logging. The closest work I’ve done here is DocIntel AI for Playwright-based automation and production backend orchestration, and Dent-Cloud for real-time dashboards driven by continuously updating data. I’d design the backend around normalized market models, a config-driven sport/league layer, and an execution service that maps user-selected custom values to the nearest valid alternate line before submit. That separation is what makes “add a new sport by config” realistic instead of fragile. For reliability, I’d add strict attempt logging, replay-safe submission records, and explicit handling for moved markets, rejected bets, user limits, and delayed receipts. If useful, I can sketch the market normalization and execution flow first, including where OAuth or credential vaulting becomes the gating constraint. Clifton

Hello, I've built full-stack solutions that integrate with major sportsbooks, successfully interfacing with real-time odds endpoints and handling the sophisticated bot mitigation measures used by DraftKings and FanDuel in 2026. My approach would use React for a responsive dashboard, a robust Node.js backend to normalize market data, and Playwright-based automation to manage the necessary token and session rotation for both platforms. I have a question, do you already have a preferred method for handling the required X-Auth-Token for FanDuel and account authentication for DraftKings, or do you need this fully developed as part of the scope? Hope to work with you.

The wager-builder idea is strong, but there's a structural fact that decides the whole project: DraftKings and FanDuel don't expose official third-party bet-placement endpoints. Everything in the brief that "mirrors the bet straight to the book" therefore depends on scraping or browser automation against their sites, and that path carries real cost, not just technical risk. Less a scraper bolted onto two books, more a place where bettors build a custom line and see exactly how far it sits from the real market. That core - the slider UI and live line comparison - is genuinely valuable and fully buildable on its own. I'd build the part that's both valuable and compliant first: account-linking where the books actually allow it, normalised football, basketball and baseball markets, and sliders showing real-time deviation from the live line, with a config-driven sport architecture so new sports are a file change. For placement, the compliant pattern is handing the pre-built wager to the user to confirm in their own DK/FD app via deep link, rather than submitting it with stored credentials. Phase 1: confirm what DK/FD actually permit, and the placement flow that fits. Phase 2: wager-builder UI with live line comparison. Phase 3: market normalisation and config-driven sports. Phase 4: compliant placement hand-off, logging and documentation.

This is the kind of betting product where the frontend is only half the work. The real value is in the market sync, account connection, bet submission flow, rejection handling, and compliance-safe integration path. I have experience with gaming/casino platforms, user dashboards, wallets, transaction logs, secure auth flows, provider integrations, and real-time betting- style interfaces. I understand how important it is for this type of system to be reliable, auditable, and built cleanly from the start. The main thing I’d want to confirm first is the integration path with DraftKings/FanDuel: whether official API access is available, or whether the first phase should focus on market tracking, dashboard workflow, and bet-slip preparation before live submission. For $200, I can offer a first milestone: - Review the required flow - Define the integration approach - Create the dashboard architecture - Build an initial React dashboard shell - Add market/odds UI structure - Prepare the bet-slip workflow - Document what is needed for live DK/FD submission Timeline for first milestone: 3-5 days If the integration access is clear, I can continue from that into the working dashboard build.

Hi, I can develop a custom odds sportsbook dashboard where users can create wagers and seamlessly push them to DraftKings and FanDuel. Users will log in, connect their accounts, set custom odds for football, basketball, and baseball markets, and place bets with real-time feedback on line changes. The system will handle bet placement, error handling, and compliance requirements, ensuring a secure and user-friendly experience. I have experience with sportsbook APIs and compliant browser automation, making me well-equipped to tackle this project. For this project, I would start by building a modern front end using React or Vue, implementing a back-end service to normalize markets and submit wagers, and ensuring robust error handling for various scenarios. A key challenge is syncing user-set odds with available lines, which I will address by implementing a matching algorithm to find the closest alternate line. I will provide a fully functional dashboard where users can connect their accounts, set custom odds, and place bets successfully on both platforms. Let's discuss the details via chat.

I have built similar bet placement tools before — not just odds scrapers, but actual mirroring and submission systems. So I understand exactly what you are trying to do. Here is how I would approach the build. The odds ingestion layer is actually the easy part. DraftKings exposes internal XHR endpoints returning clean JSON — scrapeable in 2026 with Playwright and residential proxies. FanDuel is harder. They run aggressive Cloudflare challenges, geo-restrict by state, and require a rotating X-Auth-Token harvested from live browser sessions. Token lifetime is roughly 30 to 60 minutes, so you need fresh extraction before expiry. The real challenge is bet submission. There is no documented endpoint for placing wagers. The only reliable method is simulating actual browser interactions — login, line selection, custom odds input, and checkout confirmation. That means Playwright or Puppeteer fully scripted to mirror human behavior. With stealth patches and rotating residential proxies in the target state, this is technically feasible. Here is a more sustainable alternative. Build everything except the final submission step. Users configure custom lines, the system finds the closest matching alternate line on the book, and instead of auto-submitting, it generates a deep link or QR code. The user clicks and confirms the wager manually. You keep the custom bet builder experience and real-time odds sync. The sportsbook sees a human initiating each bet. Zero compliance risk. If you w

As an experienced full-stack engineer, I can build this sportsbook wager-creation system with a strong focus on real-time odds sync, secure authentication, and reliable bet execution across DraftKings and FanDuel. I’ve worked on similar API-heavy and automation-based systems where timing, data consistency, and error handling are critical. I understand the complexity around odds movement, bet validation, and external platform constraints. I would build a React-based frontend with live slider updates and a backend that normalizes markets from both sportsbooks into a unified structure. The bet execution layer would handle submission, retries, and edge cases while keeping all credentials securely stored and fully audited. The system will be modular so new sports can be added via configuration only, and we can validate everything through a staging flow using live $0.10 test bets on both platforms. If you’re ready, I can start immediately and map out the integration approach in detail before implementation.

Hi, Before I scope this fully I want to be upfront about one thing — DraftKings and FanDuel do not offer public bet placement APIs so this would require browser automation or reverse engineered endpoints, both of which carry Terms of Service risk. If you have existing API agreements with either platform that changes everything and I would love to see them. Assuming we find a compliant path forward here is how I would build it: React frontend with real time odds display via WebSocket or polling, custom line sliders showing deviation from real book lines and a clean bet confirmation flow. Node.js backend normalising markets from both books, matching user lines to nearest available alternate lines and submitting wagers with full error handling for rejected bets, moved markets and user limits. Secure credential vault for auth tokens, strict bet attempt logging for compliance and a config driven architecture so adding new sports requires zero code changes. The system will never touch funds directly. All KYC, deposits and payouts stay entirely with DraftKings and FanDuel. One question: do you have API documentation or existing agreements with DraftKings or FanDuel or are we starting from scratch on the integration approach?
