Event-level context for related markets.

Each record retains its source event ID, so clients can review the lead move beside every related outcome.

Output

One event-level record.

Keep the lead move and its related shifts together instead of returning disconnected records for the same event.

Important boundary: sibling records provide event grouping and co-movement context. OddsQ does not label them as arbitrage, guarantee tradeability, or promise an execution edge.

Use cases.

01 / NEWSROOMS

Newsroom monitoring

Monitor qualified shifts, pull a source URL, and use sibling context to write one accurate event-level update instead of duplicating outcomes.

02 / RESEARCH

Historical research

Query retained observations with explicit timestamps and probability units. Join market records through stable source and event identifiers.

03 / BUILDERS

Dashboards and agents

Use REST for scheduled pulls, SSE for an open signal feed, or webhooks when your application should react only to configured thresholds.

04 / OPERATIONS

Filtered alerts

Filter by category and movement size, verify signed callbacks, and retain the signal, evidence, and event context in your own workflow.

Architecture Note

OddsQ provides normalized market data, live signals, and webhook infrastructure. Order execution and financial settlement take place directly on underlying source venues.
