Predkit — Orders — execution

What is predkit?

predkit’s API reference separates live routes from planned ones. The live surface covers market metadata, quotes, venue-dependent ladders, matched pairs, arbitrage signals, maker candidates and wallet rankings. Account reads, order execution and Copilot API routes are marked planned, despite broader automation language on the pricing page.

Who it is for

  • Developers building multi-venue scanners
  • Researchers comparing settlement-equivalent pairs
  • Market makers evaluating candidate pools and depth

  • Three edge measures

    Compare gross, executable and settlement-adjusted gaps.

  • Structural alerts

    Read mint/merge, categorical, conditional and time-decomposition detections.

    Our take on predkit

    Normalized records, explicit venue freshness and resumable streams make the read-only API useful for integrations. Book-depth classifications and feature-status labels must be respected; order execution is not available.
