Series, event, market, and contract model
Document the current provider behavior, required permissions, environment differences, failure cases, and evidence before treating this capability as production-ready.
EVENT-CONTRACT RESEARCH
Kalshi Prediction Trader API

Independent platform overview
How to evaluate this Trader API
A developer-focused research page for evaluating Kalshi-related event-contract data and trading workflows without implying partnership or endorsement.
TraderAPI.com does not represent this platform and does not imply an official partnership. This page organizes engineering questions so a team can compare documentation, sandbox behavior, account requirements, and operational controls using its own evidence.
Begin by writing the exact market-data, account, or order workflow the application needs. Confirm current product names, eligibility, permissions, pricing, rate limits, and regional availability directly with official sources. Treat every unverified feature as an open question rather than a promise.

Due diligence
Questions for the proof of concept
- Which objects define the series, event, market, and outcomes?
- How are price units, quantities, and payout values represented?
- Where are resolution rules and clarifications exposed?
- How should clients detect streaming gaps and rebuild state?
- Which account, eligibility, and permission requirements apply?
Test normal activity and failure states. Include invalid instruments, unavailable data, permission errors, throttling, session expiry, disconnects, uncertain order submissions, duplicate events, and state reconciliation. Record raw responses with secrets removed.
Architecture pattern
Keep the provider behind an internal adapter
Expose a provider-neutral model to the rest of the application. The adapter can translate instruments, requests, errors, stream events, and order states while preserving the raw provider identifiers needed for support and reconciliation. This boundary reduces migration cost and keeps strategy code from depending on undocumented behavior.
Place credential storage, authorization, risk checks, idempotency, monitoring, and audit logs outside the platform-specific client. A provider SDK can simplify transport, but it does not replace application controls.
Production readiness means the team can explain how the integration behaves when data is missing, requests time out, and local state disagrees with the provider.
