Live Time Delay (LTD)

The Live Time Delay (LTD) API OpenAPI specification is available for download here. Explore the API endpoints here.

The Live Time Delay (LTD) API is an advanced machine learning-driven tool within Sportradar's Insight Tech Services. It provides real-time, personalised recommendations on whether to apply, skip, or increase the live time delay for a ticket placement request. This ensures that operators can reduce latency for trusted customers while automatically increasing delay for high-risk bets, leading to improved profitability, lower risk exposure, and enhanced player experience.

The LTD API builds on two core models:

• Live Time Delay Model (LTDM) – makes player-specific recommendations based on profiling and betting context.

• Event Data Latency (EDL) Model – provides event-level delay suggestions by simulating the impact of different LTD values.

What it does

The LTD API evaluates each live ticket request and returns:

• ltdModelSuggestion: Whether to "Skip", "Delay", or "N/A" the live time delay

• ltdSuggestion: The actual delay in seconds to be applied (based on coverage and player profile)

• ltdSuggestionEdl: Additional suggestion based on EDL model

The model takes into account:

• Player behaviour (e.g. Late Bet Score, Customer Confidence Factor)

• Event risk profile

• Ticket parameters (e.g. stake, market, current match status)

If the expected margin loss (EML) from skipping LTD is low, the delay may be skipped. Otherwise, standard or increased LTD will be enforced.

When it’s triggered

Call the LTD API:

• Upon every live ticket placement

• For in-play sports and eSports covered by MTS and Insight Tech Services

• To dynamically override default LTD based on ML-model recommendation

The API is designed to support real-time decision-making at the moment of bet placement.

Input requirements

The LTD API expects the Ticket v3.0 schema, used for either ticket-placement or ticket-inform operations.

Output schema

• ticketId: Unique ticket ID

• ltdModelSuggestion: One of "Skip", "Delay", or "N/A"

• ltdSuggestion: Delay in seconds (based on coverage and risk)

• ltdSuggestionEdl: Delay suggestion from EDL model in seconds

Interpretation guidance

• Use ltdModelSuggestion to determine whether LTD should be skipped or applied.

• Compare ltdSuggestion and ltdSuggestionEdl to evaluate latency trade-offs. These can be prioritised or merged based on business rules.

• High-risk players (e.g. high LBS, low sCCF) and new accounts are automatically restricted from skipping LTD.

• Large-stake tickets are also subject to mandatory LTD, regardless of model suggestion.

The LTD API complements broader player profiling efforts by applying AI logic at the exact moment of bet placement.
