What Prop Line (BYOK) is for

Prop Line (BYOK) lets an AI assistant read your own Prop Line data through the Prop Line API with a key you supply (PropLine API key). Read-only: 12 tools (list_sports, list_events, list_odds, get_event_odds, list_event_markets, get_event_best_line, get_event_expected_value, list_futures, list_scores, get_event_line_movement, get_event_context, search_players). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.prop-line.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Prop Line. Prop Line and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which sports does PropLine cover?"
• "What MLB games are coming up?"
• "What are the moneyline odds for today's MLB games at DraftKings?"
• "What are the player prop lines for event 12345 at FanDuel?"
• "Which markets are offered for event 12345?"
• "Which book pays the most on the Yankees moneyline in event 12345?"

What it does

• list_sports: List the sports covered with their keys and whether they are active (the keys are used by the other tools).
• list_events: List upcoming and live events of a sport with teams, start time and live flag (no prices).
• list_odds: List events of a sport with odds per bookmaker for the chosen markets (game lines by default). Large answers are cut off, so narrow by bookmakers.
• get_event_odds: Get one event's odds, including player prop markets such as pitcher strikeouts or points, per bookmaker.
• list_event_markets: List the market keys available for one event, to fill the markets filter of the odds tools.
• get_event_best_line: Get the best available price per side for each market line of an event and which books offer it. The free plan sees prices blanked.
• get_event_expected_value: Compare every book's price with a no-vig fair line for an event and show the expected value in percent for each outcome.
• list_futures: List futures and outright markets of a sport (for example championship winner) with prices per bookmaker.
• list_scores: List recent and live scores of a sport for the last few days.
• get_event_line_movement: Show how an event's lines moved and which markets saw steam (many books moving the same way).
• get_event_context: Get game context for an event: venue, roof, probable pitchers, lineup status, umpire and weather (baseball events).
• search_players: Search players of a sport by name to get the names used by the player history endpoints.

BYOK key

You bring your own Prop Line PropLine API key (https://prop-line.com/dashboard). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.prop-line.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

What it is not

Prop Line (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Prop Line (BYOK) is. Prop Line (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Prop Line data: Read sports events, game odds, player props, best lines, expected value and scores from many sportsbooks with your own PropLine key. You bring your own Prop Line PropLine API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Prop Line call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.prop-line.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Prop Line rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Prop Line receives. The request we make on your behalf, including the key and the arguments, under Prop Line's own terms and privacy policy. Prop Line acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Prop Line gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Prop Line data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Prop Line (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Prop Line at any time to end all access.

Children. Prop Line (BYOK) is a general-audience service operated by the adult using the assistant, under Prop Line's own age rules.

Changes. We will post changes here with a new effective date.
